Scripting Fusion 5

Date Expression In Text+ ?

Sun, 13 May 2012 06:46:11 +0000

Is it possible to create an expression in the text node that prints the current date

I tried
Text(os.date)

Doesn't work having no luck figuring this out.

Thanks

Lua -> Python ... Function Equivalent

Tue, 10 Apr 2012 09:17:06 +0000

Hi there,

I started an adaption of Isaac Guenard's Render Manager Status LUA script to python in order to add some features. The definiton of the render manager in his script goes like

master = fusion:GetPrefs()["Global"]["Network"]["ServerName"] -- returns the  name of your render manager
if master == "" then master = "localhost" end
remote = Fusion(master, 10, nil, "RenderManager")

Anyone an idea how the third line would go in python?

Attached the original LUA script (which is quite usefull by the way)

Comp Is Loading

Wed, 14 Mar 2012 18:03:27 +0000

Is there a way to check this? Im writing a metrics script that runs through a bunch of comps in a batch folder. I open the script from an unsaved new comp. It launches everything fine and for a smaller comp I can just add a wait time of 2-4 seconds, but it doesn't work for every comp obviously, and I would much rather a way to tell if fusion is loading a comp. I was hoping IsRendering would help, but not so much. im really looking to make a

while fusion:IsLoading do
wait (2)
end

or something like that. just some time of break that is based on whether or not the comp has finished loading. Thanks in advance guys!!

Corner Pin - Key Corners With A Script

Fri, 02 Mar 2012 23:02:27 +0000

I want to write a script which would set key on all corners of a corner positioner. I tried to do it like this:

cpns = comp.GetToolList( True, "CornerPositioner" ).values()
currenttime = comp.GetAttrs()['COMPN_CurrentTime']	
for cpn in cpns:
	pos = cpn.TopLeft[ currenttime ]
	if cpn.TopLeft.GetAttrs()['INPB_Connected']:
		cpn.TopLeft[ currenttime ] = {1:pos[1.0], 2:pos[2.0], 3:0}
	else:
		cpn.TopLeft = comp.Path({})

	pos = cpn.TopRight[ currenttime ]
	if cpn.TopRight.GetAttrs()['INPB_Connected']:
		cpn.TopRight[ currenttime ] = {1:pos[1.0], 2:pos[2.0], 3:0}
	else:
		cpn.TopRight = comp.Path({})

	pos = cpn.BottomLeft[ currenttime ]
	if cpn.BottomLeft.GetAttrs()['INPB_Connected']:
		cpn.BottomLeft[ currenttime ] = {1:pos[1.0], 2:pos[2.0], 3:0}
	else:
		cpn.BottomLeft = comp.Path({})

	pos = cpn.BottomRight[ currenttime ]
	if cpn.BottomRight.GetAttrs()['INPB_Connected']:
		cpn.BottomRight[ currenttime ] = {1:pos[1.0], 2:pos[2.0], 3:0}
	else:
		cpn.BottomRight = comp.Path({})

	cpn.Refresh()

Unfortunatelly, after I run this script, corner positioner fails to update. I'm not sure if I'm calling "Path" the right way. Any suggestions?

Peyeon - How Do I Call Script From Outside Of Fusion?

Thu, 23 Feb 2012 00:06:00 +0000

hi

i managed to connect to existing comp in fusion using peyeon. i can access comp attributes, tools etc. my question is, how do i call python script? lets assume my script is named example.py and it is located in scripts/comp directory. i connect to fusion like this:

import PeyeonScript as eyeon
fusion = eyeon.scriptapp("Fusion")
cmp = fusion.GetCurrentComp()

what's next? how do i run my example.py script?

No Python

Wed, 18 Jan 2012 16:54:46 +0000

i get a strange problem, only on 2 of 7 maschines i have the LUA and Py3 Button in the Console Tab in Fu6.3 ?! So only this maschines can access our python-scripts. why python didnt work on the others. I installed python 3.2 and Peyeonscript with no effect. I reinstalled fusion... with no effect.
Suggestions?

Custom Information Within Exr Files Possible?

Wed, 11 Jan 2012 18:37:05 +0000

Hi Guys,
I wonder whether it is possible to write some custom data into an exr file when it is rendered from 3DS MAX and then read this data within fusion in order to do some automated tasks?

One practical example:
If you are familiar with stereoscopic workflows you might have come across the annoying issue that a very wide field of view (or wide eye separation) skewes the resulting left and right images in a way which shows a huge vertical (!) difference of objects in the image. The closer to the left or right side of each image the bigger is the vertical difference.
Luckily one could counter balance this by putting a simple DVE after the loader in fusion. This is what I usually do.
But rather than adjusting it always manually it would be nice to just read the FOV value of the camera (out of the exr file) and apply the DVE with the appropriate settings with a script.

Does that make sense?
And more importantly: Does anyone know a solution?

Thanks a lot!
Uli

Assimilate Scratch To Fusion?

Is Eyeon or any script guru working on a script to go from Scratch to Fusion??
Apparently Nuke has one.

The Old Wirelesslink

Tue, 06 Dec 2011 21:43:30 +0000

Can it be rewritten so that whenever you copy/paste a WirelessLink fuse, it keeps its input? It's because of the ImageControl Input Control used, I guess as similar behavior can be seen when copy/pasting a BG "From Image" gradient. Pretty annoying.

A FileControl keeps its setting.

Lowtech Stereo Workflow

Tue, 06 Dec 2011 13:20:52 +0000

Well, I want to have a simple yet flexible stereo workflow that I can use for a shortfilm that will kick off soon.

Stuff I did: rewrote the Switch fuse to something that maintains DOD and has just two inputs for Left and Right footage that I can switch between using a checkbox. There is one Master Switch, renamed in the comp accordingly with a comment added to it to make clear it is a "Master." Then then are multiple copies of that same Fuse, renamed to indicate these are slaves, with a twist: the checkbox control is controlled by an expression making it look at the state of the Master Switch fuse and copying it. Comments clearly indicate these as being "Slaves." Finally, a Saver with a comment that says "SwitchMe"

I want to add en event that, when saving, looks through the nodes in the comp, search for a Master Switch first, check to see which input is being used--left or right--then look for a Saver with a "SwitchMe" comment and change the path and filename according to the footage used.

Pretty lowtech, using the comp variable, fixed filenames, no versions and using settings preset in the Saver node itself, in the comp.

This is the scriptlib I wrote, but it already bugs out on line 3. "attempt to index a globel 'ev' (a nil value)" No clue what the problem is.

ev = AddEventSuite("Composition")
function ev:OnSave(event)
local toollist=comp:GetToolList()
for i, tool in toollist do
  if tool.TOOLS_RegID == "StereoSwitch" then
   print("Found a StereoSwitch")
   if tool.Comments == "Master" then
	print("It's a Master")
	if tool.SwitchInput == 1 then
	 print("Switch is set to Right")
	 eye = "right"
	else
	 eye = "left"
	 print("Switch is set to Left")
	end
   end
  end
end
for i, tool in toollist do
  if tool.TOOLS_RegID == "Saver" then
   print("Found a Saver")
   if tool.Comments == "SwitchMe" then
	print("This one needs to be switched")
	if eye == "Left" then
	 print("Setting path to Left")
	 tool.Clip = "Comp:\left\Stereo.0000.jpg"
	else
	 print("Setting path to Right")
	 tool.Clip = "Comp:\right\Stereo.0000.jpg"
	end
   end
  end
end
end

Checkbox Control In A Fuse

Sun, 04 Dec 2011 19:45:08 +0000

If I toggle a checkbox control on a fuse node, how can I make it change the tile and/or text color of the node itself? It's just a visual assist and not something really important, but I just would like to know if and how it can be done.

Performing Basic Operations On Image Channels In A Fuse

Wed, 30 Nov 2011 09:43:37 +0000

Doing plenty of multi-pass compositing you end up with lots of addition, multiplication, division and subtraction operations in your comp. I've always been doing this with a Channel Boolean, experimented with custom tools too (try inverting with a boolean and Ct and compare the results.)

What is the most efficient way of doing this? Would making a basic fuse that just does one of those operations be the most efficient? A Ct? Or stick to the old Boolean?

Looking at this link:

http://www.vfxpedia.com/index.php?title=Eyeon:Script/Reference/Applications/Fuse/Classes/Image/ChannelOpOf

I'd love to turn those examples in a working fuse, but I didn't manage to do it yet. I realize this is basic fuse stuff, but I must be missing something. If maybe a kind soul would make for instance a "Plus" fuse using this snippet, I could be on my way.

img_out = img_bg:ChannelOpOf("Add", img_fg, { R = "Fg.R", G = "Fg.G", B = "Fg.B", A = "Fg.A" })

Thanks in advance.

Listing Node/macro Inputs?

Tue, 22 Nov 2011 02:29:11 +0000

Hi fellow Fusion users!
Is there a way through EyeonScript to list the inputs on nodes/macros?

e.g. VectorMotionBlur has available input connections, Input, Vectors, and EffectMask.
I can only find GetInputs() which lists all attributes on the node...
This is a problem because I have some macros with many uniquely named inputs.

Cheers,
Jorx

High/low Prode Tool

Mon, 21 Nov 2011 23:19:21 +0000

Hey Guys!!

Im a new member here, Ive been using Fusion in feature production for about 2 years now and have been quietly lurking, but now I need to ask for your help

I am trying to make a tool to go through a sequence and and return the high and low values of the red channel. So instead of probing a single frame of setting up a reference, I want the tool to go through the entire sequence find the overall high and the overall low, then use those values in a BC to clamp or fit my values down.

I have been messing around with ways to do it with nodes in fusion and package a macro, but i cannot seem to find an automated way, and I do not know enough about lua or fusions scripting to get it right.

I have a decent ammount of experience in Houdini, Maya, and PRman, so I have been using what I know from them to come up with what I want to accomplish in script.

Mind you I know this is in correct and it does not work what so ever. I only wrote this to try and layout a pplan of what I needed it to do and how I would do it in onther contexts.

CurrentNode.Input1=Input
Input.GlobalIn=F1
Input.globalOut=F2
Time=Fit01(F1,F2,0,1)
High.F=Input.R1.High
High=0
X=0
Low.F=Input.R1.Low
Low=0
Y=0

If(Time=0, High.F=High, High.F=X)

If(X>High, X=High, High=High)

Print `High`

If(Time=0, Low.F=Low, Low.F=Y)

If(Y
Print `Low`

again it is not in any particular language, kind of a VEX/PRman morph style, but what I am trying to say is.

I need to take the frame range from the Input 1 of the tool, fit that to a normalized range of 0-1. Then, If we are at Time 0 (first frame of the range), then that value will be stored as the high and low values, if not the current value will be compared to the stored high or low, and so on.

At this point I am stumped. I have made a few versions of the tool that use reference frames and you can take an educated guess at the frames that will have the highest or lowest value, however it is not accurate enough, and I am to go about it that way I might as well simply look at the viewer and input the value into a BC.

If anyone has any advice, input, flaming, yelling, constructive criticisms, not so constructive criticisms, or suggestions I would trully appreciate it. TIA!

Ontooladded Eventscript Workaround

Sat, 19 Nov 2011 04:22:26 +0000

The eventscript at vfxpedia is an example of how to implement an OnToolAdded eventscript by using OnActivateTool.
It makes use of metadata for new comps and activated loaders (for the first time = created).

Works with dropping files from the explorer, toolbar loader creation, bins etc.
Doesn't work on old opened comps, else you would end up creating tools on each loader you select.

Moving The Polyline Or Mask Pivot Point

Mon, 14 Nov 2011 19:48:05 +0000

Hi,

Is there any way of moving a polyline mask pivot point (center) by script? For example moving the center point for a whole group of polymask nodes while keeping all polyline points in the same place.

I found an old topic with more or less the same question http://www.pigsfly.c...?showtopic=4193 but copying the settings, modifying every point XY value and pasting it back is not a very smart solution.

I know, that holding the M key while dragging the center point will keep the polyline in place. Another solution would be the point editor (E key) menu that offers a nice offset function for a point or group of points.

Am I missing something essential here?

Python Import Problem: Parent Module Not Found

Sat, 12 Nov 2011 11:58:55 +0000

Hi,

I was just doing some first steps with Python. I have this import directive in a comp script:

from xml.dom.minidom import parse

and although the code further down seems to be working, I get this error message from Fusion:

C:/Users/Public/Documents/eyeon/Fusion/Scripts/Comp/Import XML Subtitles.py:8: RuntimeWarning: Parent module 'C:/Users/Public/Documents/eyeon/Fusion/Scripts/Comp/Import XML Subtitles' not found while handling absolute import
  from xml.dom.minidom import parse

I changed the import to

import xml.dom.minidom

and the error is gone (and everything still works). Afterwards, I changed the line back to the first version and the error message doesn't come up again until I restart Fusion. What's going on? What's the right way to do this?

Get Current Settings

Fri, 21 Oct 2011 13:01:31 +0000

Hey there Folks!

I was just wondering if it´s possible to get the Attributes from a selected slot ( S1, S2, S3.. etc under the tool name bar )

I know how to get the slot name by using >> slot = Background.GetCurrentSettings()
..now how to get for example the "Color" on the Background tool on that Slot?

thanx.

Using The Dist3D Function

Thu, 20 Oct 2011 11:41:03 +0000

Hi!

I'm trying to calculate the distance between a camera and a 3d locator using the dist3d() function inside an expression modifier (http://www.vfxpedia....iers/Expression).
Unfortunately I cannot get it to work. Here's my full expression code:

dist3d(point_sharp:GetValue("Transform3DOp.Translate.X"),point_sharp:GetValue("Transform3DOp.Translate.Y"),point_sharp:GetValue("Transform3DOp.Translate.Z"),cam_render_baked:GetValue("Transform3DOp.Translate.Z")*.1,cam_render_baked:GetValue("Transform3DOp.Translate.Y")*.1,cam_render_baked:GetValue("Transform3DOp.Translate.X")*.1)

I also tried this one, it didn't work either:

dist3d(point_sharp.Transform3DOp.Translate.X,point_sharp.Transform3DOp.Translate.Y,point_sharp.Transform3DOp.Translate.Z,cam_render_baked.Transform3DOp.Translate.X*.1,cam_render_baked.Transform3DOp.Translate.Y*.1,cam_render_baked.Transform3DOp.Translate.Z*.1)

I tried dist3d(0,0,0,1,1,1) and there was a correct result, but my version just outputs 0.

Can someone please give me a hint on whats wrong with my expression?
Thank you!

regards,
Henning

Compname In Text Tool - Script

Wed, 12 Oct 2011 15:09:47 +0000

Hi everyone,

I'm trying to create a TextTool in my Python script. This TextTool should contain the "CompName" modifier so that it produces the current comp name. Of course I could read the name via the comp.GetAttrs()["COMPS_FileName"] function, but then the fusion comp wouldn't change the text tool by itself every time I save a new version of the flow (e.g. from "Flowv01.comp" to "Flow_v02.comp".
Is there a way that I can write the comp name into an expression? -> text_tool.SetExpression(Text("comp_name_var_here"))

Best regards

Forgetful Wireless Node

Wed, 07 Sep 2011 15:50:31 +0000

Hello,

is it only me or is the fact that copied and pasted wireless forget their Input annoying anyone else?

We use some wireless up to 20 times in a comp and it's annoying to get the input over and over again. I don't understand why this happens in the first place? What's the benefit?

Is there a solution other than copying it as Instance (which causes other problems)

Thanks Chris

Scan Folder Issue

Tue, 30 Aug 2011 14:50:35 +0000

Hi everybody,
I'm trying to search for a file in the comp directory via script. I know the name of the file and of course the comp path.
Now: i'm using readdir() to look in the path, but maybe i don't know how to use it correctly because i can easly find out a list of folders and go through it, but i want to automatically look in the comp main folder and subfolders, until the maximum depth for any of them, to see if my file is already there. Wrong approach?

All this stuff is meant to be part of a script to relocate sources that are not in the right place(comp path).

Thanks in advance

Getting Glview Objects List Or Glview Object Of Active View

Wed, 24 Aug 2011 07:53:57 +0000

I want to enable Buffer LUT on some of my viewers. I can do this for right or left view using comp.CurrentFrame.RightView and comp.CurrentFrame.LeftView objects. But how do I refer to my floating views? How do I get their names?
Second thing - Is there a way to refer only to active view?

3D Space Input Size ?

Tue, 23 Aug 2011 08:54:43 +0000

Hi Group,

is there a way for a 3D tool to get Input's Width / Height , especially for Image Plane?
I am trying to create a simple 5x5 locator set-up for Bicubics (with the technique mentioned here: http://www.pigsfly.com/forums/index.php?showtopic=7009 ) and i'd like to get them equally distributed based on Input (ImagePlane or Shape3D_Plane). I can get it hardcoded with Shape3D_Plane, but with my humble skills i don't know how to achieve it with ImagePlane3D.

also is there a way to get AE's equivalent of "=value" in SimpleExpression ?

i.e. i want to have Locator3D.Translate.X = ImagePlane3D.Tanslate.X + Locator's own X value - to have Locator translated when i move ImagePlane and also to be able to move Locator separately, with its handles in 3D view. I know a can get it with Calculation modifier, however having 5x5x3 mods for such set-up is a bit messy.

thx in advance

Placing New Tool In Last Clicked Position

Thu, 28 Jul 2011 10:48:41 +0000

I want the 'M' key to create a 'Merge' node right where I clicked in the flow. I've created a simple script:
fusion = Fusion()
composition = fusion:GetCurrentComp()
composition:AddTool("Merge")
placed it in Scripts:Tool folder and mapped it to 'M' key. Unfortunately the tool doesn't want to show where I clicked but it jumps to 'zero' position. When I choose tool from applications menu everything is ok - new tool is placed just where I clicked.
What am I doing wrong?

Read Renderer Mode

Tue, 19 Jul 2011 12:08:53 +0000

Hello everyone,

I'm trying to search my comp for any 3d renderers that are running in OpenGL mode so that i can submit it to our renderfarm manager with a certain machine limit.

When I try to read the found tools using this:

renderer_used= comp:GetToolList(false, "Renderer3D")
for i = 1, table.getn(renderer_used) do
	renderer_type = renderer_used[i].RendererType
        print(renderer_type)

I only get this response:
"Input (0x3F9B3CB0) [App: 'Fusion' on 127.0.0.1, UUID: 24ae7fef-4d97-4c02-aa6b-2fed5a255e4e]"
I don't know how to turn this into a value that I can compare to anything.
Is there any way that I can read a string that says "RendererOpenGL" like it says in the flow file?

Frame Saved Script - Write Into Txt-File

Mon, 18 Jul 2011 15:40:32 +0000

what i want :

a simple Frame Saved Script , which put some Infomrations in a Text-file per Frame.

1. Comp-name
2. current Framenumber
3. maschine - name

Quote

log = io.open("y:\\Fusion\\renderlog.txt","a")
log:write("\n ttt3")
log:close()

so far... but if i want to add the comp-name like in my "changesavername" -script

"compName=string.gsub(comp:GetAttrs().COMPS_Name, "%.comp", "")" i only get:

[string "compName=string.gsub(comp:GetAttrs().COMPS_..."]:1: attempt to call method 'GetAttrs' (a nil value) ???

and how i can get the computer-name ?

Modify Script To Load Fbx Sequence So That I Can Move It In Timeline?

Tue, 12 Jul 2011 05:01:16 +0000

I've got a very primitive script that when copied into the 'Frame Render Script' area of an FBX mesh, will allow me to play an FBX sequence like (Elmer_000.fbx, Elmer_001.fbx, etc.)

MyPadding=3
MyFrameNum=string.format("%0"..MyPadding.."d", time)
ImportFile="D:\\ElmerFusionFBX\\Elmer_"..MyFrameNum.. ".fbx"

Currently, I've got to set Fusion's ending frame to the highest number in the FBX sequence.

Thinking ahead, I'd like to be able to move the FBX mesh around in the timeline, and certainly not be limited as to what I can put into the ending frame number for Fusion.

Any thoughts on how I can create a script with a bit more flexibility - that knows that I've moved it in the timeline, but will always start with the first Fbx file(xxx _000.FBX), and ... maybe, be able to read the directory and SEE for itself what the highest FBX sequence number is?

I'd like to be able to just give it a folder name and the 'name' of the sequence, and have it work, where ever I put it.

BTW - I'm agnostic as to scripting language. If Python is the way to go, I'll go in that direction.

I currently program in C# but have used Pascal, C, C++ and even 6800 and z80 assembly language (which probably really dates me). But, I've never coded for Fusion.

Thanks!!!

Passthrough Saver By Expression / Script

Wed, 29 Jun 2011 12:56:45 +0000

Dear Forum,

in my Flow i used the 8-Switcher-Macro, (http://vfxpedia.com/index.php?title=Settings_and_Macros/Switch8er_Description)
to setup a complex composite. with simple expressions
i switch tool-branches automatically based on the switcher value. (COLOR_SELECTOR.Input1) is my trigger.
e.g.
COLOR_SELECTOR.Input1 - 0 = red CC
COLOR_SELECTOR.Input1 - 1 = blue CC
COLOR_SELECTOR.Input1 - 2 = green CC

at least i wanted to switch 6 different savers on&off,
not by frame range, but by the switcher value.

i tried Frame/Start/End Render Scripts

if COLOR_SELECTOR.Input1 == 0 then
Saver0:SetAttrs({TOOLB_PassThrough = false}) 
print ("PASSTHROUGH OFF")
else
Saver0:SetAttrs({TOOLB_PassThrough = true})
print ("passthrough on")
end

Even with the right loop/print result, "passthrough on", the saver keeps writing files....

can anyone give me a hint ?
how i can correctly pass through a savernode
based on a given value of another node ?
is it the right way to put these script into the savers' (e.g. start/end) scripts-window ?

thanks in advance,
marc

How To Read Out Loader Depth?

Metadata

Mon, 27 Jun 2011 09:42:44 +0000

Hi all,

Simple question... I have this in a fuse to read the metadata of the Fuse's input and dump the values.

local img = InImage:GetValue(req)

metadata = img.Metadata

dump(img.Metadata)

I get this back

table: 09593D58
	screenWindowWidth = 1
	comment = mycomment
	order = C { r g b } A
	Filename = Y:\filepath\P1_allMattes_285.exr
	screenWindowCenter = table: 09593D28
		1 = 0
		2 = 0

Is this the only metadata that Fusion can read from an EXR? I have put in other fields like Artist and Hostname but they do not appear. I'm still looking for an app that will read the metadata from the EXR independently to be sure it's actually there (XNview won't load the file) so I thought I'd fire the question while I was looking.

Cheers

J

PS.. it's an EXR straight out of Houdini, I haven't tried to add the metadata through any other app.

EDIT: This is more a Houdini problem I think as I can of course read all arbitrary metadata I supply to an EXR via Fusion but it's worth asking in case there's a houdini bod out there

"unfinished Capture" - Can't Look For "(" In A String?

Sun, 06 Mar 2011 05:08:10 +0000

from the console:

> string.find("(as)df", ")")
> string.find("(as)df", "(")
[string "string.find("(as)df", "(")"]:1: unfinished capture

why would fusion be able to search for ")" but not "("? in the documentation, it says "\" is the only escape character? i've tried all kinds of variations, like "\(" or having the character in a variable and using that variable instead... nothing.

does anybody here know what's up with that? i don't need it for my current script any more but it would be good to know for the future.

Setting 3D Controls Values With Intool Scripts

Sun, 23 Jan 2011 16:25:45 +0000

Hello!

It's pretty straight forward to set any parameters just entering a Name = Value in the Frame Render Script field.
But it doesn't work for compound parameter names like those being used in 3D tools (e.g. pEmitter).

"Number = 5" will work whilst "SphereRgn.Translate.X = 5" won't, although it works in simple expressions.

What is the syntax?

Inheriting Translation Link Transform Node

Thu, 06 Jan 2011 22:04:58 +0000

Hi and a Happy new year,

I am working on a plugin where i need to inherit a traslation from one offset control (as 'automatic' bounding box pivot) to another one (as the user hand offset).
i tryied several things, digging in the input.h and standardcontrol.h, where i found a nice ACP_center for the anglecontrol that let him inherit translation from another another node.
I am currently using a SetSource inside the process function which makes the process to run endlessly. That a solution, but not the good one.

Does someone have any ideas, or the transform node source code ?

Thanks,

Updated Script: Destabilize Transform

Thu, 16 Dec 2010 13:20:33 +0000

Hi,

on vfxpedia, Gringo suggested to make the destabilize transform tool script work with more than just Xf nodes. I have extended the script a bit but it would need some testing before I'll upload it to vfxpedia. Basically, it should work with masks, the grid warp, the Text+ tool and everything that has a center or angle control. It will auto-detect what's available and display the proper checkboxes.

However, I had to change the way the script operates. Previously, it would connect to the STABLE positions and use the "invert transform" feature found in Xf tools. Since this doesn't work for other tools, I had to connect to the tracker's UNSTABLE values now. I don't know if that gets you different results or why this was done in the first place (maybe a remnant from DF 4?). Would be nice to get some feedback :-)

Here it is:

3D-Coat Applink For Fusion

Wed, 17 Nov 2010 20:33:13 +0000

Hi guys and gals! I am working on new script for Fusion, utilizing AppLink functionality available in 3D-Coat since version 3.5. Last week i have released Luxology modo version of AppLink script - info and download available here: http://www.3d-coat.com/forum/index.php?showtopic=6945
Video:
Download: http://www.multiupload.com/8T27YUMBBP

In short, it should be simple UI with 2 buttons and drop-down list, you should be able to output 3D geometry from fusion to 3D-Coat, edit UV's and paint textures (normals, displacement, specular and diffuse), then bring it back to fusion's 3D environment. UI is very simple as i said (and as you can see in the video of modo version): import and export buttons + drop-down list to get user's input of export type (so 3D-Coat would know what you want to do with imported file), like UV, Per-Pixel painting etc.

My problem is that i am not very advanced fusion user in general and never scripted anything for fusion (even though it should change now, new fusion's 3D/shaders/rendering abilities looks simply fantastic and it's the main reason we have decided to make AppLink for fusion before Nuke version, Nuke can't do some of the things on 3D/shaders side that fusion can do). It's very hard to find any python scripting for fusion info, i can't find even one working example of python script for fusion with GUI ! So i'd ask my questions here with hope to get answers from you guys

1) GUI - what should i use? Can i use AskUser to create GUI with 2 buttons and drop-down list which will pass user input to the script? Is there some nice example of GUI made using AskUser? Or should i use something like Tkinter, PyQt or WxPython?

2) I am frustrated a bit with Python versions and Peyeon... I want to use Python 2.6 x86, not 3.1 x64, so i should use PeyeonScript-6.1.win32-py2.6, correct? But the question is - can i trigger python script from fusion to be executed in external Python 2.6 interpreter and not in internal (or external) Python 3.1 interpreter? If so, how can i do it, can someone please show me example of such a script, which will be executed in 2.6 interpreter when triggered from inside fusion?

Thanks in advance, i'd probably have some more question in the future. Hope that AppLink would be quite useful for fusion users, especially considering new Fusion 6.1 features (3D, shaders, Hardware render).

Matrix4 Method Syntax And Usage

Fri, 12 Nov 2010 12:30:28 +0000

Hello

I am trying to manipulate a matrix written in the metadata.

Sofar I can access the values via:

local r11 = result.Metadata.worldToCamera[1]

Then I thought why not using the Matrix4 function to perform operations?

create an empty Matrix4
copy the data in there,
use matrix operations
and create a new matrix in the metadata, to make it readable.

I thought the Matrix4 Object works like this

local mt = Matrix4{}

then by

mt[1] = r11

I can copy my data in there (that might work dont know how to chekc that)

then I thought

mt:Inverse()

should do the trick to give me the inverted matrix

finally I am writting that out in the EXR Header...

newmetadata[m_md] = mt

but I get this error:
Unsupported type for custom data!
Any ideas how to convert that back in the end ?

When I create a matrix the "normal" way

local mt = {}
for i=1,4 do
for j=1,4 do
mt[(i-1)*4 + j] = 0
end

I can copy data in there, write it in the exr header, but not perform any Matrix4 operation....
so maybe someone has a clue how to overcome that.
I even tried using the matrix.lua library from luaforge.... but that caused other problems and other errors...

Cheers

Need Help In Scripting..

Wed, 10 Nov 2010 19:27:22 +0000

Hi All,

I was recently trying to make a script which will help me to switch through the settings(S1, S2,.. till S6) of all tools present in the comp. I have made the script, and using that(with help of a dropdown optionbox) I can switch settings of the whole comp.

now I want to hide that settings button from all the tools present in the comp, as its hidden in Loaders. So that, nobody can manually change any individual tool's settings. can we do it? I'm not a pro in scripting, plz guide me on this matter.

thanks,

Vector2, Vector3F Method Syntax

Thu, 04 Nov 2010 15:15:36 +0000

Anyone knows the syntax for Vector2 or Vector3f.

In fusion 5.3
a = Vector2/3f (1,2,3)

a.Distance() -- fusion crashes
a.Length() -- fusion crashes
a.Normalize() -- fusion crashes

Is there any way to get Distance between 2 vector2/3(as 2/3d coord), length, or normalized Vector ?

Thanks

Fuse Particle Creation In Particle Operator Not Emitter

Wed, 03 Nov 2010 08:56:30 +0000

Hi,

I am using Fusion 5.31.78 so fuse particle are enabled.

My goal is to add extra particle in empty screen space (between original particles created by an emitter).

I followed the few sample code i was able to find : "Particle Emitter Test.fuse" "pFromFile-obj.Fuse", and i succeed in creating extra particle in an operator, but...
they are not modified by the next operators (a turbulence in my test), and they do not seem to be really added to the particle entity.
Do you have any clue here, or a sample piece of code ?

Maybe some of you know how the particlegroup works and can give me some tips. let's say how to unify them in one piece ? to simplify the access to the particle (i am using part:GetGroup(j):GetParticle(i))?
What Particles(req.SourceImage,self.iD) is referring to ?
Can i use something else that 'self.ID'?

Isn't it a better idea to merge the emitter and the modifier(which add extra particles) to resolve that ?

Any help would be greatly appreciated.

thanks,
Xavier

Scripting-Bug When Animating Inputs?

Sun, 31 Oct 2010 19:46:19 +0000

Hi,

having done a bit of Fusion scripting until now, I feel a bit stupid about this... but I can't find out how to animate inputs properly. If I create, for example, a transform tool....

"Transform1.Center = XYPath({})" works as expected. But if I don't call ".Center" directly, but store the input reference in another variable, this doesn't work anymore. For example, save this as a tool script and run it on a transform tool. It should animate the "Center" coordinates with an XYPath:

controls = {}
inps = tool:GetInputList()
   for i, inp in inps do
      if inp:GetAttrs().INPS_DataType == "Point" then
         table.insert(controls, inp)
  end
end

-- doesn't work:
controls[1][TIME_UNDEFINED] = XYPath({})

The input isn't animated. The code above, however, is based on the Import Boujou Track example script, which means the script shouldn't work! I can't test it because I lack a boujou file, but can anybody get this to work?

By the way, the "Animate 3D Parameters" tool script is using a different technique to animate an input that works. If you add this line to the script above:

controls[1]:ConnectTo(XYPath())

the input gets animated as expected.

I'm about to submit this to bugs@ but I'd like to know if somebody can confirm this bug. I'm running Fusion 6.1 build 697.

Opencl Fuses?

Fuse Memory Management

Sun, 17 Oct 2010 08:52:12 +0000

For the Fuse I'm currently writing, I've taken a lot of inspiration from eyeon's example fuses. However, I'm still unclear as to how memory management should be handled. Do I have to set all temporary images I have created in the Process() function to nil at the end? When do I call collectgarbage()?

The Frame Average Fuse has this piece of code in case nothing is to be done to the input image:

local img = InImage:GetValue(req)
OutImage:Set(req, img)
img = nil

It differs from the Null Fuse, which doesn't set img to nil but instead has img:Use() in it:

�

local img = InImage:GetValue(req)
img:Use()
OutImage:Set(req, img)

cheers

Edl Import

Wed, 22 Sep 2010 20:03:23 +0000

Hi,
I'm a new user. I tried to make a post yesterday, but it didn't make it?!?

I'm tying to import an EDL into fusion. I've tried different formats from both Premiere Pro CS5, and Generation(!). The EDLs don't import properly. With research, I've found that fusion only supports DPS EDLs. I've tried, without success, to find a sample DPS EDL...

So, I'm writing an eyeonscript to import EDLs. Parsing the .edl is easy, but I'm having trouble applying the attributes to a loader.
I'd like to either create a loader AND set its attributes, or create a loader and then set its attributes. Basically, I want to "paste settings" on the loader I've created.

I do not have very much experience with LUA or eyeonscript.

Why doesn't this work:

composition:Lock()
LDR = Loader({Clip = location})
LDR:SetAttrs({TOOLNT_Clip_Start = "69"})\
composition:Unlock()

If this is a common question, or there's a readily available answer in the forum, sorry. Please point me in the right direction.
Thanks.

Edl Import

Tue, 21 Sep 2010 16:40:25 +0000

Hi,
Fusion's EDL Import feature isn't working correctly with any of the EDLs I've tried (from Generation(!) and Premiere CS5). Examining the documentation, I've found that only DPS EDLs are supported (I've also spent a long time trying to find a DPS EDL for reference...no luck).
So I'm writing a script to parse a Premiere Pro EDL and create loaders and dissolves.

How can I create a loader and set attributes in one step? Specifically, how can I create a loader and set length, trim in, trim out, global in , and global out?

I tried to create a loader from a clip and then SetAttrs on the loader. Like:

LDR = Loader({Clip = MyCLip})
LDR:SetAttrs({TOOLIT_Clip_TrimIn = "69"})

This doesn't work. I want to basically "paste settings" on a tool.
Any advice would be appreciated. If this is a common topic or there's an obvious answer already posted, just point me in the right direction!

Render End Script After Network Rendering Finished

Thu, 09 Sep 2010 23:39:45 +0000

Hi guys,

Pretty simple and straight forward task.
When we leave the office in the evening, we set the farm to render the comps. In the morning, we have to convert all the frames into AVI's in order to use it in the edit suite.
This is obviously an unnecessary step because we have clever LUA (or Python) who could take care of this automatically.

And we don't want to apply the script manually to all the comps in the rendermanager via "end render script". It should automatically convert ALL comps rendered on the farm.

There must be a script out there for this. If not.... I'll give it a go....
Can someone point me in the right direction or at least make me aware of any traps when dealing with the render manager via scripting? Never did that before.
I.E.: how to apply a standard "render end script" on the network via script?

Thanks a lot!
Uli

Fuse Quastions

Fri, 03 Sep 2010 10:54:47 +0000

i try to teaching the fuses..
a`m looking in to blur.fuse, and find this:

function Process(req) 
	local img = InImage:GetValue(req)
	local blur_x = InBlurX:GetValue(req).Value / 720
	local locked = (InLockXY:GetValue(req).Value > 0.5)
	
	if locked == true then 
		blur_y = blur_x
	else
		blur_y = InBlurY:GetValue(req).Value / 720
	end

why we did division by 720 ?

thanx.

Upd:
on VFXpedia page there is little bit another example:

img:Blur(result, {
		BLUR_Type = "Gaussian", 
		BLUR_Red = 1,
		BLUR_Green = 1,
		BLUR_Blue = 1,
		BLUR_XSize = blur_strength/img.Width, 
		BLUR_YSize = blur_strength/img.Width,
		})

so, i can imagine that blur fuse, which built in Fusion distributive - suppose that input image width = 720 ?

Image Name Of Current Frame

Thu, 02 Sep 2010 07:52:08 +0000

This script could be buggy and it misses Looping, TrimOut, HoldLast Frame, Reverse, Clip Lists and Proxies but for the other attributes it should work (GlobalIn, TrimIn, HoldFirst ...)
I've written it step by step and commented so you can play around with the source.
It will output the frame and image name of "Loader1" in this case. You can adapt it to go through all loaders or the selected as you wish.

If there is a convenient way of doing this it should be here one day:

Fuse Loader?

Pastesettings

Fri, 20 Aug 2010 10:03:50 +0000

Once more, I try to find a way to duplicate something that can be done by hand in a comp by script.
I know there is CopySettings and I can use Paste to duplicate tools, or use SaveSettings to a file and then load them onto a tool but how can I recreate "Paste Settings" without some file created?
Do I have to feed the Clipboard content into a GetInputList from the target tool or is there some way to use Paste to work with a tool?

While I'm on that topic, I have a .setting file that I apply to script created Savers with LoadSettings and while it sets the Output Format (OpenEXR) and Process Mode correctly, the Format settings (Compression etc.) don't get applied. When the Savers are already there and I run the script again to apply the Settings from the file again, everything is fine.
Is that normal behaviour and I should use wait(1) and then apply the settings again?

Ok, found a working combo that sets the Clip AND the right settings:

R_Saver = comp:AddTool("Saver",RM+2,yM+3)
R_Saver.Clip = RFN
R_Saver:LoadSettings(CBPath.."_Saver.setting")
R_Saver:SetAttrs({TOOLS_Name = "R_Saver", TOOLB_NameSet = true})
R_Saver.Clip = RFN

For now, I'm using SaveSettings to a temp file and load it on my new camera. I don't want to keep the transformation though (imported fbx)

camera_L.Transform3DOp.Translate.X = 0

doesn't work and before I try to delete the Transform entries in the temp file by script, is there any way to Remove the linked animation or set the Tranlation Group to default? Once again, things the context menu can do just fine but if I wanted to do things manually, I wouldn't script them.

Ok, I don't know why it didn't work before (I tried nil and 0) but

LCam.Transformation.Translate.X = nil
LCam.Transformation.Translate.X = 0

works to cut the connection and then setting it to zero.

Fuse Performance Question

Thu, 12 Aug 2010 10:18:11 +0000

Hey

I am trying to do something like a soft clip in Fusion that all values above a certain threshold become "log"ed (the log function)... that all works well.. then my teammate said why not put it into a fuse? So I tried to copy that function in a fuse, but the fuse is much slower :-(
I guess it is the way I wrote it and thought maybe you guys have some improvement ideas (regarding the fuse). Here is what I did in the custom tool
if(r1>n2, log(r1)*n1+1, r1) (for each channel respectivly) -it still has the downside if the threshold is smaller then 1.0 that the log function produces negative values... but we just want to lower all values above 1.0 so that doesnt matter for the moment.

I just guess as fuses are "scriptable" nodes there are doomed to be slower compared to the c++ code from the custom tool... but maybe you have some ideas on that... maybe opencl would be a way...

Cheers

Fusion Lua Events Converted To Python

Sun, 01 Aug 2010 00:45:33 +0000

Since it is very difficult to find information about python scripting in fusion, I'm dropping some questions, hoping for some answers:

1) How can I use the event handlers in Python scripts. It is possible to, i.e., convert this script to python:

while composition == nil do
 
end
 
globals.ev = AddEventSuite("Composition")
 
function ev:OnStartRender(event)
 
        local toollist=comp:GetToolList(false, "Saver")
 
	for i, tool in toollist do
 
		if tool.Input:GetConnectedOutput() then
			self:Default(event)
		else
			-- report the problem
			msg = "The saver named ".. tool:GetAttrs().TOOLS_Name .. " is not connected to any other tools.\n\n"
			msg = msg.."Select OK to continue anyway, or Cancel to exit."
			
			ret = comp:AskUser("Warning: Orphan Savers!", {
				{"Warning", Name = "Warning", "Text", ReadOnly = true, Lines = 5, Wrap = true, Default = msg},
				})
			
			if ret then
				self:Default(event)
			end
		end
        end
end

2) Can the python script be saved as .py in stead of .scriptlib ??
3) Is there more documentation about python in fusion besides the single example on VfxPedia?
4) Is it possible to call a Python script from within a LUA eyeonscript?

A Very Basic But Small Loader Renaming Script For Stereo Footage

Tue, 20 Jul 2010 15:40:47 +0000

I'm just learning this stuff and this is probably already existing somewhere more or less (though a search here for "rename loaders" scored meager results), I wanted to post this script for more experienced scripters to glance at and hit me with a rolled up newspaper for any redundancies/inefficies/risks/omittances. Maybe someone could even get some use out of this or modify it for their own uses.
It's not doing anything great but I plan to have other scripts referring to loaders by these names, that should clean up all other tools by a lot and make them very readable and scene independent.

--Rename Loaders for stereo footage by Simon Isenberg

loaderlist = eyeon.GetLoaders(composition)
 
for i, tool in loaderlist do
    if tool:GetAttrs()["TOOLST_Clip_Name"] then
        for j = 1, table.getn(tool:GetAttrs()["TOOLST_Clip_Name"]) do
			local eyestart,eyeend = string.find(tool:GetAttrs()["TOOLST_Clip_Name"][j], "_L_")
			if not eyestart then eyestart,eyeend = string.find(tool:GetAttrs()["TOOLST_Clip_Name"][j], "_R_") end
			if eyestart then
				local truncname = string.sub( tool:GetAttrs()["TOOLST_Clip_Name"][j],eyestart+1,string.len(tool:GetAttrs()["TOOLST_Clip_Name"][j])-9 )
				print("Loaded Clip: "..tool:GetAttrs()["TOOLST_Clip_Name"][j])
				print("Renamed Loader: "..truncname)
				tool:SetAttrs({TOOLS_Name = truncname, TOOLB_NameSet = true})
			else
				tool:SetAttrs({TOOLS_Name = "", TOOLB_NameSet = false})
				print("--> Loader doesn't match criteria: "..tool:GetAttrs()["TOOLST_Clip_Name"][j])
			end
        end
    end
end

Some thoughts/concerns I have about this so far:

-Throwing away the last 9 characters of the ClipName only works as intended for _####.XYZ so it's a bit inflexible but since that's all the footage I expect, I happily dispensed with looking for file extension and number patterns, if needed they can easily be implemented anyway.

-I couldn't get it to only look for _L_ and _R_, so it looks for any upper case letter inbetween two underscores. That could of course spell trouble if there is a version _G_ of a scene or somesuch. I tried to make my own char-set but[_L_]* looks for any underscores or L, not the exact construct. Is there a way to only look for exactly _L_ or _R_ I'm not aware of?
I could make it two lines, look for _L_ in the first and a second line "if not eyestart" that looks for _R_, which works but is hardly elegant and just seems redundant.

-It resets Loadernames that lose their correctly named stereo footage but only when the user runs the script. Any thoughts about having it run on an event like OnActivateTool? Not all comps might be for stereo and there isn't really a reason to run it for every tool that get's selected.I could check and break if the activated tool is not a loader but since it fires at the start of someone manipulating a loader instead of after the manipulation is done, it kind of defeats the purpose. Maybe I'm jsut too caught up in efficiency and with today's computing power, nobody cares for scripts running every frame/every tool activation. For now, I'm trusting our compositing department (not even a handful including me at the moment) to use the script consciously when they want to.

-x,y = string.find... since I only need/want x, can I omit y somehow or send it to nirvana without taking up a variable?

-I went back and forth between assigning truncname or just keeping the string.sub() in it's place. The latter makes the lines somewhat hard to read but again, saves some resources, especially if you kill the print feedback. Anyone has something to say about the usage of variables vs methods?
Personally, I don't even like the "attrs = GetAttrs()" people are using as it obfuscates what's going on (especially hidden brackets) and doesn't save that much typing. On that matter, anyone got around crafting an auto-complete set for eyeonscript yet?

Disclaimer: Sorry for my long, capsulated and convoluted sentences, I think like this. It's a mystery to myself how I am even interested in writing short and neat code. I hope someone reads this wall of text anyway and has some thoughts about this, seeing how dead the scripting part of this forum is, I don't have high hopes but it already helped me writing my thoughts down and I can link to this when I discuss it with people.

How To Set Loader Trim Value Via Script?

Mon, 12 Jul 2010 11:20:48 +0000

Hello everybody,

I try to set some Loader Values, and have problem with the Table Values
I can set the Clip Name with:

loader = Loader1
loader.Clip = "test.mov"

And I can set the Loader Name with:

loader:SetAttrs({TOOLS_Name = "testLoader"})

Now I try to set some table Values like TrimIn and Out

But: loader:SetAttrs({TOOLIT_Clip_TrimIn = 5}) won�t work,
and loader:SetAttrs({TOOLIT_Clip_TrimIn[1] = 5}) throw a syntay error.

So my question is: How to set TableValues with eyeonScript??

Thanks Friedrich

Fuses And Access To Fusion Classes

Fri, 09 Jul 2010 09:19:13 +0000

Hey

I was trying to access Fusion Classes from a fuse !?!?!
Is that possible at all ?
Or can fuses just process what ever can be transported on an image stream ?

@ eyeon: Is there a place where clearly is stated where which language with what abilities can access what inside fusion ???
Where can I access fusion classes ?
-scripts, expressions, fuses, just console...
Can Fuses be written in Python now ???
Stuff works in the console, then it is different in the framerender scripts, then normal scripts, fuses ?!?! and expressions....

Python: How To Use Askuser() Correctly

Mon, 05 Jul 2010 11:07:52 +0000

Hi,

I'm trying to convert some of our Inhouse Eyeonscripts to Python, now that Fusion 6.1 supports it and I wanted to learn it anyway
I'm having a problem with the AskUser() function.
In eyeonscript, it expects to get an input dialog table like this: {"InputName", Name = "input please", "InputType", Options = options_var, Default = 0}
I've read that python handles tables like this one (with "key" and "value" entries) as "dictionaries", but in this special case the values "InputName" and "InputType" don't need (or must not have) any key. Is there any solution for this in python dictionary objects? Is it that in python dictionary object every value needs a key? How can I create a valid input table for the AskUser function in python?

Thanks and best regards,

Dirk

How To Highlight Changed Parameter

Wed, 30 Jun 2010 15:36:26 +0000

Hi fusioneers,
In ColorCorrection node, I was wondering how to identify if any parameter in any of the tabs, have been modified.
Like if a parameter, suppose reds, are modified but that too in the mids or shadows; is there a quick or better way to identify without actually clicking and opening each section or subsection. This task is very tedious specially when the comp has lots of CC nodes.
Like there is a script online, which highlights any animated node, Is there a script to highlight or identify a change in default parameter of any given node?

many thanks ...

Sequences In Folder

Wed, 23 Jun 2010 09:34:36 +0000

Hi,

Not been doing much scripting lately so incredibly rusty I know LUA can't list folder contents, at least without some 3rd party modules so I'm asking what is the a good way of doing so?

All I need is to search a folder for arbitrarily named sequences and create loaders for them. I could write a Python script to do the listing but I thought I'd check if anyone has other ideas as I actually don't know Python.... yet!

If Python is the way, can I launch Python scripts from LUA in a similar way to using os.execute for DOS shell commands?

And yes, I'm still on Fusion 5.21 with 6 coming too late for the current project :/

Thanks

Select Upstream?

Wed, 12 May 2010 18:53:10 +0000

Hi!

Is there any way to easily find/select the tools upstream of the currently selected tool? I've googled and read through the scripting docs and VFXPedia, but haven't found anything that seems to apply or work -- I tried the FlowView:SelectUpstream(), but it's not documented and it doesn't seem to do anything (although it doesn't error either...).

The following is my bash at it, but it's crushingly slow (probably because it has to do a GetAttrs() for every input of every tool that it finds). It also doesn't select mask inputs, but that could be fixed... I would be very grateful to know about any speedups or better code you might have to hand. We're working with very large comps (1600+ tools) so performance is important.

-- In the "upstream" function, I get the inputs of the currently
-- selected tool, then discover which are "Image" inputs. If it's an
-- image, I get the tool connected to it, then call upstream on
-- _that_. Eventually, all dependencies should have been visited and
-- recorded as {toolname = tool} pairs in the found table, which is
-- passed down the line as needed.

function upstream(found, which)
local inputs = which:GetInputList()
for i = 1, table.getn(inputs) do
local input = inputs[i]
local a = inputs[i]:GetAttrs()
print(" - "..a.INPS_Name)
if "Image" == a.INPS_DataType then
local o = input:GetConnectedOutput()
if o then -- Might be nil if nothing connected.
local t = o:GetTool()
local ta = t:GetAttrs()
found[ta.TOOLS_Name] = t

upstream(found, t)
end
end
end

-- return found
end

-- Start work here.

composition:Lock() -- Lock the composition so user can't modify it.

print("Printing found attributes as we go.")

sources = {} -- Table of source tools.
upstream(sources, tool)

-- Print a list of the tools I found.
print("Source tools found:") dump(sources)

-- Now I clear out the current selection and select the tools I found.
flow = composition.CurrentFrame.FlowView
flow:Select()
for k, v in sources do flow:Select(v) end

composition:Unlock()

i am working on a stereo rig in fusion. I use expression and the frame render script.
My rig works well, but when i make a render or a preview, the scripted element don't refresh on each frame, they keep the value where i launch the render.
Someone have an idea on how correct this bug?
I am working with fusion 5.3 build 55

thanks

Scripting Resources

Mon, 10 May 2010 15:11:56 +0000

Hello peeps,

as far as passive knowledge goes I generally understand how scripts are built but I'm wondering what the best way to actively learn the syntax and structure is.
I believe that to learn effectively from how other people's scripts I still need to study the basic operations.
Is there a resource which explains the various logical operators and actions as well as the syntax and lexicon step by step?

I have the impression that VFXpedia doesn't do this broadly enough. Am I right?

thanks

Sticky Front Projection

Fri, 07 May 2010 22:09:13 +0000

Well, whenever I have to project a single frame from a tracked sequence, I start by copying the tracked camera and deleting all the keyframes except for the one I want. Then I duplicate the loader and isolate the corresponding frame (trim in and out, set it to loop) or use a timestretcher with a fixed value instead. It's okay for one frame, but sometimes I end up projecting through several cameras to patch up different parts of the image. So I would like to do it in a more elegant and faster way.

I tried to explain what I want to do in the screenshot attached (there is no real working flow yet.) I hope it makes sense?

Set Keysframes On Gridwarp

Sun, 18 Apr 2010 16:21:02 +0000

Hi
Does anyone know how to set keyframes on GridWarp via script.
For example I want to use 3x3 grid. I create GridWarp1 node in the flow, configure it to have 3x3 cells, then I type in

GridWarp1.DstGridChange = BezierSpline
GridWarp1.DstGridChange[comp.CurrentTime+1] = 1 --(I don't really know what value it has to have)
GridWarp1.DstGridChange[comp.CurrentTime+2] = 2

and I'll get 3 keyframes.

But when I go through keyframes, they all have 8x8 grid in the viewer but show 3x3 frame in the GridWarp's GUI.

Eyeonscript Help Monoflowtostereo

Sun, 18 Apr 2010 07:18:14 +0000

Hey All,
I need to take about 100 flows that are mono and do a simple Instance Node and replace loaders to create a Stereo Flow. It sounded simple enough... I can script in Python and have tried to tackle eyeonscript to get the basics. I can't get it working for me. So if there are any eyeonscript guru's that could give me some pointers or tips...
I have tried to parse the .comp file and have found it to be a monster task with all of the inputs and outputs reconnecting with a "instance" flow. I know that Fusion 6.1 will come with Python support but I have no idea when that will come and I need to be finished in 3 months. So, any help would be much appreciated. Also if anyone has any other ideas maybe generations has some functionality I don't know about...

hi,

can i use "if ... then... " f.e. in the pCustom Tool ? and how?

i can define variables in pCustom tool , f.e. in the "setup"-tab?

Accessing The Comments Field?

Mon, 15 Mar 2010 11:45:56 +0000

Hi,

in the console (of Fusion6), I can get a tool's comments with the line:

print( MyTool.Comments[TIME_UNDEFINED])

from what I get the text string of the comments field.

I tried the same whithin "MyTool", writing in the FrameRenderScript field:

print(Comments[TIME_UNDEFINED])

which returns me: nil

or

print(Comments)

which returns me the connected node: Text <026D6EF8>

How do I access the comments text string using a toolscript?

Addtool Problem

Thu, 25 Feb 2010 12:50:35 +0000

Hey

I´m currently fiddeling around with a script created custom tool. Everything works fine exept the correct placing.

> TRIGGER = comp:AddTool("Custom", 1, 1)
> = TRIGGER
Custom Tool (0x000000001D48B3D0) ...

-> everything is ok. I can adress the node like expected ... but it is spawned on 1,1 position

> TRIGGER2 = comp:AddTool("Custom", -32768, -32768)
> = TRIGGER2
nil

-> ok, now the node is created on the right spot (using the auto-positioning coordinates), but I can´t adress it anymore.

Am I missing something? Thanks in advance.

Fusion Units Conversion

Tue, 19 Jan 2010 10:28:35 +0000

Hi

We try to create a script which need a relation between the 2d unit of a merge (from 0 to 1, which is a percentage of the picture) and the 3d unit.
In fact we'll have to replace some picture by other one which are the same but cropped in a different size (and not in the center). SOme of these picture are on 3d layer. As it is more difficult to adjust the position on a 3d layer (to compare the 2 picture to make them fit perfectly), what we want to develop is to make a script that use the position value of a 2d merge (used to fit the 2 pictures) and then convert this values in the 3d view to the 3d position of the image plane.
But as the 2d unit is a percentage and the 3d more an absolute value we have to make a conversion with a formula. The problem is that the 3d unit seems to change depending of the size of the source picture.
Does someone know how to have a real value in the 3d view, how to do this conversion ? Or maybe something already exist ?

I hope I was clear

thanks

Poor Man's 3Dpoint

Sat, 26 Dec 2009 12:17:11 +0000

Hi forum,

If you have a correctly tracked scene and you want to find the position of a particular pixel in 3D space you can use a feature in Nuke called 3DPoint. Don't think of it as a pixel per se, a more practical example would be a window's top right corner for instance.

I'm not really a Nuke user and I have my own little way of getting the right coordinates, using a 3D application. What I do is, I create a long line that is parented to the camera, pivots around the cam's nodal point and aims towards a marker object that I use to visually select the pixel I'm after while looking through the tracked camera and with the footage viewed in the background.

I go to the first frame of the sequence and move the marker in position and create a key, then I go to the last frame and again put it in position and create another key.

I then clone that line two times (I only created two keys in the previous step,) go to frame one and remove this first clone from the rig, so that it's on it's own, no longer parented to the camera and no longer aiming automatically to the marker. But in doing so, I baked position and rotation so visually you shouldn't see a difference between the baked version and the original line that's still part of the rig.

Then I do the same with the last keyframe, this time using the second clone.

Finally I move a null / helper / locator along one of the baked lines until I've found the intersection of those two baked lines, and those (world) coordinates gives you the correct 3D position.

Basically, projecting a line out from the camera, you know that the 3D feature lies somewhere along that line and by projecting through multiple images, I can find the 3D position of that feature.

Now, I'm happy with this little trick but imagine doing this for a lot of points, and it's a huge timesaver to be able to do this in Fusion straightaway. Would it be possible to do this using a script? Maybe something like that already exists? Thanks in advance!

How To Get The Resolution Of The Input Of A Macro?

Wed, 16 Dec 2009 11:22:09 +0000

Hi guys,
Krokodove's Beams tool is very slow. So what I usually do to speed up things is this:
I put a Rsz before the Beams to quarter the resolution. Then I apply the Beam and quadruple the resolution afterwards. Then I merge it back onto the original image.
This speeds up the beams quite a lot.

Now I want to put all this in a macro.
Therefore I have to know the resolution of the macro's input.
Because if the image I want to apply the beams to is 1024x576 the first Resizer should set itself to 256x144.
But if it is 1920x1080 the Rsz should be 480x270.

Any thoughts on that?

Cheers

Frame Render Script

Wed, 16 Dec 2009 01:26:05 +0000

Hi,

Can someone point me in the right direction. I have a comp that renders 7 different sized Quicktime files. I'd like to add a Frame Render Script to the 8th Saver that makes a proper sized thumbnail .jpg. I want the .jpg saver to save just one frame which I have chosen as the thumb, and not render the rest of the seq.

I looked in the FU5 scripting manual, but didn't see any examples that I could cobble from...
Thanks.

Macro From Script

Thu, 03 Dec 2009 10:08:31 +0000

Hi,

I've got a fuse problem so I'll need to use a macro instead. I was wondering how to drop that macro into the flow using a script? I got:

Quote

You'll need a table containing the tools to be grouped. This can be done manually, by loading a .setting file, or by using the comp:CopySettings() function. Then, create the GroupOperator tables and plug the tools table into that

from

http://vfxpedia.com/index.php?title=Useful_Scripts

I'm not sure I fully understand it but, is it possible to get the script to read the macro.settings file and 'copy' it into a table to be used by comp:Paste

Any head start on this would be appreciated beacause I'm kinda scratching my head over this at the moment

Cheers

Fuses And Crashing

Thu, 03 Dec 2009 09:59:47 +0000

Hi,

A vague question but... Is there any reason having multiple fuses (the same one) in a comp would cause fusion to crash?

My fuse takes in 5 or so image inputs (wirelessly) and does a bunch of compositing ops and outputs the result image?

It's fine if you step through the flow but if you were to open the comp and view the last node in the flow Fusion bombs out. This happens in FU5.21 and 5.3 but not in 6. Going to 6 is not an option.

I was just wondering if there were any known issues. If not I'll post the Fuse to Eyeon and see if I'm doing anything stupid within the fuse itself.

Cheers

Does anyone know how to set the Channel for a view, for example, right view, to Alpha , or Depth, or Color, etc., from script.

I tried the following, not work:

b_view.View.Channel=3 -- TO Alpha
composition:SetData(Prefs.Comp.Views.Right.Channel, 3)
composition.Views.Right.Channel =3
b_view.Channel=3

Thanks for any help.

360� Rotation

Sat, 28 Nov 2009 11:48:08 +0000

Hi all,
I have 3 Points: P1; P2; PM. PM have an Position Script that move it to the middle from P1 and P2:

Point X= (p1x+p2x)/2
Point Y= (p1y+p2y)/2

p1x and p1y is the centre from P1
p2x and p2y is P2

And p3x and p3y have expression: Point(P1.Center.X+0.2, P1.Center.Y)

Now I want that PM rotate correctly when I move P1 or P2, see the Picture. My Number Out Expression for the rotation is this:

acos(((p2x-p1x)*(p3x-p1x)+(p2y-p1y)*(p3y-p1y))/(sqrt((p3x-p1x)^2+(p3y-p1y)^2)*sqrt((p2x-p1x)^2+(p2y-p1y)^2)))

This works fine, but only for 180�, then the PM Rotation flip/reverse from 180� to 0�.

You have a idea what I can do?

Command Line Launch And Wait For Fusion

Thu, 26 Nov 2009 13:53:14 +0000

Hey,

Another embarrassingly simple query. I have this test script:

fuEXE = "U:\\applications\\fusion\\521\\Fusion.exe"
fusion = Fusion("localhost")
if fusion == nil then
	os.execute(fuEXE)
else
	print("Fusion already open fool!")
end

print("I'm now ready to do stuff!")

which is fine if Fusion is open and I can then start to open comps and run scripts. However, when fusion isn't open the script seems to stall during/after Fusion is launched.

What is the protocol to do this? All I want is to be able to open Fusion if not open and then do stuff

Script To Convert Footage On The Fly (I.e. Tga To Avi)?

Tue, 24 Nov 2009 13:40:08 +0000

Hi everyone,

Years ago I wrote a little script in DF4.
It was pretty basic.
It just converted a given folder (with tga or whatever footage files) into a differnet type i.e. AVI or MOV or TIFF.
Then I made a few registry entries and I had a convenient rightclick menu in Windows Explorer to convert a whole folder (and subfolders) on the fly.

Before I start to rewrite this script in Fu6, I would like to know if someone did something similar already and if he/she would like to share it?

All the script did was picking a pre setup flow with exactly ONE Loader and ONE Saver (and whatever additional tools inbetween) and simply exchanged the footage path and target file(s). It changed the flow length accordingly and started rendering.

If noone did that already or simply doesn't like to share - what do you guys think of such a script?
Any useful? Shall I rewrite asap, or no interest at all?

If someone thinks this is great and he/she wants to dig into it, I'd be happy to share my old "*.dfscript" files.

Any other ideas? What else should be in this script?

cheers

Looking For A Complete List Of Error/exit Codes

Mon, 23 Nov 2009 20:49:37 +0000

Hi

I was searching a list of all error or exit codes for Fusion 5.31.74

The only thing i found is thoses codes, found here :

http://vfxpedia.com/index.php?title=Eyeon:Manual/Network_Rendering/Console_Slave

The ConsoleSlave produces a numeric exit code when it completes, which can be checked in a batch file or by a third-party render manager. The following exit codes are common:

* 0 means that the render or other operation completed successfully, and ConsoleSlave exited normally.
* 10 means there was a problem with rendering the comp (see the render log for details), or that the process was interrupted by a CTRL-C signal.
* 20 means there was some problem with the startup - DLLs may be missing, or a problem with a plugin was encountered, or there was a problem obtaining a licence. Check the console slave's output, or re-run it with the /verbose switch for more information.

But it seems to me that there is more than only 3 exit codes ?

Am i right or wrong ?

Thanks

[Fuse] Particle Color And Image

Wed, 18 Nov 2009 16:59:08 +0000

Hi,

I'm just looking at the ParticleEmitterTest.fuse and I want to cannibalize it to create a simple image based particle emitter. I have two questions really. How are the particles coloured when the 'UseColor from Region' is set and how can I colour the particles based on p.position?

What I don't understand is what Pixel() is in:

if clrsrc == 1 then
   pix = Pixel()
end

and, most things like position are set thus:

p.Position = Vector3f(1, 10, 10)

Heyho...

I�m trying to get my head around fusion scripting for the last couple of days and I�m stumbled upon a little problem.

Can it be, that the AskUser PathBrowse field let you only point to a file (exactly the same as the FileBrowse field does) and not to a directory-path as its name intends, or is it just me and my simple logic that tricks me here..

I�m running F6.0 build 511 and working on a little saver-setup-automation script.

Hey,

I know I can run functions from external scripts with dofile() but is it possible implement a similar library to the eyeon.scriptlib? I don't see any examples where external lua libraries are called (plenty of C libraries thoug ) or where I could set any environment variable within Fusion.

I have tried to create a new user.scriptlib file and dump it into the root as as helpfile suggests but is there anything special I need to declare beyond the functions to get it to work coz right now i can't call any functions from within it.

Fuse - If No Input

Fri, 13 Nov 2009 14:32:55 +0000

Hi,

I'm not sure how to detect if an input has no erm.. input

say I have an image input:

InImageSpec = self:AddInput("Specular", "Specular", {
		LINKID_DataType = "Image",
		INPID_InputControl = "ImageControl",
		})

if I try to use InImageSpec and there is no input for it then the fuse fails. I'm pretty sure the fuse fails whether or not InImageSpec is used in the fuse. So, is there any way of outputing a default value if there is no input specified?

Check If A "end Render Script" Is Finished.

Fri, 13 Nov 2009 00:41:17 +0000

Hi,
I need to query Fusion to find out if it has finished rendering AND all the End Render scripts have returned. The comp:IsRendering() returns false as soon as Fusion rendered all the frames but before the End Render scripts have finished. A work around I'm doing now is to generate a temp file before the render starts and remove it as the last command in the End Render script, but its not a very pretty solution.

I'm using the executebg('command', true) in the End Render script, so Fusion does wait for the process finish, I just don't know how to query Fusion about it. It's a low resource process that takes a couple of minutes, so checking CPU/RAM doesn't work either.

Anyone know of a way to ask Fusion if a processes that Fusion has started is still running?

Reading External File

Fri, 16 Oct 2009 18:25:29 +0000

Hi
I am pretty new to Lua but I've done some scripting in fusion already but nothing big. The help file for this topic I found pretty skimpy so I require your help. I have a text file that looks something like this

1324.5 322.5 324.5 34.4 90.0 90.0 45.0
114.5 325.5 524.5 32.4 90.0 90.0 45.0
...

the basic idea is to read a file line by line and extract each number to a variable. first three numbers in a line are xyz position next is xyz rotation and the last is an extra parameter. Any help would be appreciated. Thanks in advance.

Create Regular User Interface In Fusion Environment, No Flow Chart.

Wed, 14 Oct 2009 19:31:43 +0000

Is it possible to create new buttons on fusion interface with function of the tools provided by Fusion or some Macros created by yourself?

Besides that, is it possible to not using the drap and drop, and the flow chart. Instead, just function like regular GUI, when click on some button , can go to some window directly to do the operation, like selecting region of interest, picking the color of a pixel, or , the result directly appears in some window?

Also, is it possible to have four windows in Fusion, i.e., one is the original picture, the second is the one displaying region of interest selected, the third one is the temporary picture working on, the fourth one is the final picture?

Abs To Relative Paths Script

Tue, 13 Oct 2009 17:05:35 +0000

I always thought there was a script to do this already but.....from the wishlist

Quote

* New It would be great to have a script Relative_Paths.eyeonscript which would convert absolute paths in loaders and savers to relative ones.

The algorithm is pretty simple.
For example, the composition is stored in D:\Work\Project\Scene\Composites\Shot\Scene-Shot_v01.comp and a source clip is D:\Work\Project\Scene\Scans\Shot\2048x1556\000000.dpx
The script would compare the two paths, find the common part (D:\Work\Project\Scene\) and change it to Comp: (Comp:Composites\Shot\Scene-Shot_v01.comp), then everything after ":" followed by a slash in the composition path would be changed to ".." (Comp:..\..\Scene-Shot_v01.comp).
After that, the rest of the clip's path would be added after the last slash (Comp:..\..\Scans\Shot\2048x1556\000000.dpx).
It should be a comp script to be able to change all the paths in a composition or the paths in selected nodes optionally.--Gringo 09:23, 25 September 2009 (EDT)

I made an initial look into this and came up with one for loaders (atm). Unfortunately when you change the clip name it changes the global in/out values too but I can fix that later with moveClip or something.

not finished...

Intool Scripts Not Working

Wed, 30 Sep 2009 23:42:02 +0000

Hi,
I need a InTool script to fetch me some comp attributes, just like I would in the console with:

=composition:GetAttrs().COMPN_RenderStartTime

I would like to in the InTool script of a tool do:

f5 = Fusion()
composition = f5:GetCurrentComp()
renderStart = composition:GetAttrs().COMPN_RenderStartTime

.. similar to the example on page 18 in the Fusion5 script manual.

Currently everything is failing,
Fusion() returns: attempt to call global 'Fusion' (a nil value)
comp returns a reference to a composite object, but GetAttrs() returns attempt to call method 'GetAttrs' (a nil value)
fu return a refernce to a unknown object, but :GetCurrentComp() doesnt work.

Since its says it supposed to work in the manual I would like to figure out how to fix it, anyone have any ideas what I'm doing wrong here or a workaround?

Cheers
Christoffer Hulusjö

Edit:
After some more digging I found out that the InTool way seems to be to fetch it by doing comp.Name, comp.RenderStart, etc.. Which to me seems weird, instead of the way in the script manual where it would work the same as in the console. (comp.Name will not work in the console for example) Is there any documentation about this?

Fusion Minimum Value Scripting

Wed, 30 Sep 2009 15:46:57 +0000

Hey guys,

I'm attaching a blend from another node to the blend in the current node. I'm doing this by using the simple add expression function and dragging the cursor to the blend. this is fine, except it is too heavy. I can add "-.1" to the expression giving me good results, however when the blend is 0, the expression makes it -0.1. I am not familiar with Lua, and I can't come up with, or find a solution to make the expression have a minimum value. How can i clamp this?

On another note, fusion 6 users should be a aware, that locking tracking information usually causes everything attached to break at some point.

thanks for your help!

More Freebies

Wed, 23 Sep 2009 07:58:07 +0000

Hi folks,

got another couple of freebies for you to play with.

I added 2 view shader fuses for Fusion 6:

hos_HSV_VS, just a simple test, allows you to view HSV or H,S and V seperately (mapped to all RGB channels).

hos_SimpleSpatialTonemapper_VS, a fuse that allows you to tone map your view window based on the simple spatial tone mapping algorithm by K.K. Biswas and Sumanta Pattanaik.
I'll be compiling this one as a separate node as well with some added extras.

There's now also a separate page that lists all the plugins/scripts/macros/fuses in one go for easy download (no need to dig through the entire blog), since i haven't posted everything i wrote in here, this might be nice starting point.

have fun with 'm

Using Python When 2 Fusion Are Open

Tue, 22 Sep 2009 19:59:56 +0000

Hi

I cannot access, from python, the comps on fusion if they are loaded from a second fusion application running.

Is there a way to avoid that issue, since i cant force the artists to have only one copy of fusion running

Thanks

Python Questions

Mon, 21 Sep 2009 10:08:39 +0000

Some questions about python interface in fusion:

1. Is python 3.1 supportet? If yes how could I load the DLL, because I always get an error when starting a script in 3.1 "DLL could not be found"
2. If you have a template with different Loaders, that have to be changed by the script. Would you do text replacement in this case or would you load the comp, change it by script and then send it to the render manager?
3. Must the fusion application always run to use python script or is there also a non GUI support?

Best regards

Multiple Comp File Editing

Thu, 17 Sep 2009 12:31:51 +0000

Hey,

I was wondering what the best way to batch process a whole bunch of comps is. I'm thinking simply changing saver settings at the moment. I've thought about parsing them all as txt files but that somehow feels a bit inelegant so maybe there are some other ways?

Sorry to be a bit vague but it's something i *may* end up doing rather than something ASAP so I've not dedicated much brainpower to it yet

Python Questions

Thu, 17 Sep 2009 12:28:36 +0000

Hi, I just start with python programming in Fusion and just want to know some basics as well as strategic decisions regarding scripting:

1. I have a template (finished Fusion Project) where I just have to cahnge the clips in loaders and savers. What would be the best choice, to just replace the text of the clip names in the projet file or to do this by a script? It could be, that the clip length will change as well as the length of the rendering. Txt replacement is quite easy in python and also there would be not so many failures if a script may fail.
Also starting the renderin in the render manager could be easier, but what would you prefer?

2. Render manager: Is it possible to control the render manager completely like pause, stop, move up and down render job, get current render list.
Do internal scripts like the "Run Command" do also work and which engine (computer) will execute the command?

3. I want to use python 3.1 and not 2.5. Does this also work? I want to use some additional features of 3.1 and it will cause al lot of trouble and work if it will not work

4. Does the acual python API also work with 6.0 version or do I have to wait?

Best regards

Python Questions

Thu, 17 Sep 2009 09:55:56 +0000

Hi,
I have to perpare a external control of Fusion Rendering and just want to know some things about the python interface to fusion.
1. Is it possible to use the actual 3.1 version Python for scripting? I need some of the new features in Python, that are not included in the 2.5 version.
2. Render Manager: I have a template, with some file input an one file outputs. I have to change the clip names in input and output. Is it better to change it in the texfile with text replacement and just send the finished file to the render manager or will it be better to change the input and outputs by scripting and then send it to the render manager by python scripting?
3. Render manager control: is it possible to control the render manager by python scripting?

Thanks for the answers

Input Switcher Fuse

Wed, 16 Sep 2009 14:11:32 +0000

Ok, to begin with, I've never done any Fusion/Fuse scripting, so this will not be an optimized or efficient script I believe..

I've written a Fuse which basically Switches between 4 input streams using a simple if then else structure. Now the problem here is that lets say i have only 3 inputs connected and the 4th input is empty, the Fuse fails. I can see a simple logic but unable to find the right way out... This is sort of like the Switcher in Houdini. In fusion, for simple 2 stream switching one can always use a Dissolve but our specific requirement was a 4 input switch. And the idea is to just switch inputs, not animate or blend over time.

This works if all 4 inputs are connected.

FuRegisterClass("Switcher", CT_Tool, {
	REGS_Name = "Switcher",
	REGS_Category = "Fuses\\eyeon",
	REGS_OpIconString = "Swtch",
	REGS_OpDescription = "Switcher",
	REG_OpNoMask = true,
	REG_NoBlendCtrls = true,
	REG_NoObjMatCtrls = true,
	REG_NoMotionBlurCtrls = true,
	})

function Create()
	InImage = self:AddInput("Input1", "Input1", {
		LINKID_DataType = "Image",
		LINK_Main = 1,
		})
	In2Image = self:AddInput("Input2", "Input2", {
		LINKID_DataType = "Image",
		LINK_Main = 2,
		})
	In3Image = self:AddInput("Input3", "Input3", {
		LINKID_DataType = "Image",
		LINK_Main = 3,
		})
	In4Image = self:AddInput("Input4", "Input4", {
		LINKID_DataType = "Image",
		LINK_Main = 4,
		})
	InSwitch = self:AddInput("Switch", "Switch", {
		LINKID_DataType = "Number",
		INPID_InputControl = "MultiButtonControl",
		INP_Default = 0,
		{MBTNC_AddButton = "1", 		MBTNCD_ButtonWidth = 1, },
		{MBTNC_AddButton = "2", 	MBTNCD_ButtonWidth = 1, },
		{MBTNC_AddButton = "3", 	MBTNCD_ButtonWidth = 1, },
		{MBTNC_AddButton = "4", 	MBTNCD_ButtonWidth = 1, },
		})
	OutImage = self:AddOutput("Output", "Output", {
		LINKID_DataType = "Image",
		LINK_Main = 1,
		})				
end

function Process(req) 
	local switch = InSwitch:GetValue(req).Value
	if switch == 0 then
		local img = InImage:GetValue(req)
		img:Use()
		OutImage:Set(req, img)
	else 
	if switch == 1 then
		local img2 = In2Image:GetValue(req)
		img2:Use()
		OutImage:Set(req,img2)
	else
	if switch == 2 then
		local img3 = In3Image:GetValue(req)
		img3:Use()
		OutImage:Set(req,img3)
	else
	if switch == 3 then
		local img4 = In4Image:GetValue(req)
		img4:Use()
		OutImage:Set(req,img4)
				end
			end
		end
	end
end

Where exactly am I going wrong here ??

Thanks,

Hello,

I am new to this forum as well as fusion scripting. What is wrong with the following code.
When i execute this i am getting the following error *** attempt to call global `checkPassDirectoryAndLoadContents' (a nil value) *** and I am unable to view it in the particular viewer i am defining.

Can anybody tell me....

Thanks...

The code is

mydirname = "Ambient"
ambloader = checkPassDirectoryAndLoadContents (bgpasspath, bgambdirname)
print (bgambloader)

-- This function reads the contents of the given pass directory
-- loads the footage if presents

Evaluation Of A String

Wed, 02 Sep 2009 09:33:46 +0000

Hello!

I'm trying to compose a variable name out of string fragments and need to turn the string into the variable value.

Here is an abstract example I've tried to implement:

ScanTtl = Loader1.GlobalOut-Loader1.GlobalIn+1
Go = "Scan".."Ttl"
StyledText = lua.eval(Go)

lua.eval doesn't work.

Variables state:
ScanTtl = 48
Go = "ScanTtl"

I'd like to call Go and get 48. Is it possible?

hi everybody,

i want to add a custom user control to a script-generated tool. i have added a merge like that

myMerge = Merge({Background = myBackground.Output, Foreground = myForeground.Output, ApplyMode = "Screen"})
myMerge:SetAttrs({TOOLS_Name = "Mrg_" .. myMergeName .. "_screen"})

and i want to let's say add a custom slider control to this merge within the script. how can i do that?

Scripting In Learning Edition

Thu, 27 Aug 2009 17:47:15 +0000

Are there any known bugs/restrictions in the learning edition (build 447) when it comes to scripting?

The simple command

a = Blur()

returns an error�

[string "a = Blur()"]:1: attempt to call global 'Blur' (a nil value)

although the node is created in the flow view.

Copy Dod

Tue, 25 Aug 2009 15:39:10 +0000

hi there,
just noticed that few macros here don't work in Fu6 because of wrong DoD usage. Like expanding matte and using MatteControl to Combine Alpha - Copy for replacing matte keeps bg DoD.

So I'm trying to make node to copy DoD from one tool to another. From release notes for Fusion 6.0 Build 440 it looks like DoD scripting is supported:
- Added DoD support to Output�s GetValue() scripting function�s attrs.
- Added GetDoD() scripting function to Output.

typing to concole
a,b = Text1.Output:GetValue(1.0)
==b
returns DoD as a table, anyone knows how to use it in simple expression or InTool script?

thanks

Getting Styledtext Content

Thu, 20 Aug 2009 07:29:10 +0000

Hi!

I can easily get the value of any tool's attribute in a frame render
script in order to use it as a text e.g.
StyledText = Merge1.Blend

But I couldn't manage to get contents of a Text.StyledText or other
"text edit" fields in such a manner.
StyledText = Text1.StyledText doesn't work

Is it possible at all?

Tracker Node

Sun, 19 Jul 2009 11:11:23 +0000

Hi there

I have some difficulties with the "Track Forward From Current Time" Tracker node function.

When i click the appropriate button everything works like it should.
When I try to activate the same function by code such as

trname.TrackForwardFromCurrentTime = 1

("trname" is the nodes actual TOOLS_Name attribute)

I get following results: "Render started at Sun 12:56PM (Range: -1000000000 to 550)"
And nothing seems to happen (only the end range is OK).

Is it even possible to trigger the tracking function by script?

Best regards

Update Output From Frame Render Script Without Changing Current Frame Of The Comp?

Wed, 08 Jul 2009 19:57:19 +0000

I'm displaying values from an xform with a frame render script in a text node � la

StyledText=Transform4.Angle

At the moment the values in the text node only update when I scrub through the timeline and not on the fly when I change the values in the xform.

Is there a way of updating on the fly without changing the current frame of the comp?

Thanks in advance.

Size Of Text String

Tue, 07 Jul 2009 09:01:40 +0000

Sorry if this is a newbie script question, but I've searched around for a couple of days for this.

I want to size a bar behind some text, to the same length as the text. How do I get the width of the text in an expression and use it to resize the X size of the bar? Or do I need to use a script to do this. I'm reading names and need to match the size to the input text width.

Thanks

Import Ascii Tracking Data ?

Sun, 05 Jul 2009 01:55:08 +0000

I have AE and Mocha for AE....
needless to say mocha can at times be a kick ass tracker.

is there a script available to import tracking data that was intended for ae...
(i know the full version of mocha has Fusion export...but i just have the cheapo AE version)

or if not, where would one start to write a script to import keyframes based on ASCII text
thanks

here is an example of ascii data from mocha

Value From A Tool?

Tue, 30 Jun 2009 10:49:35 +0000

import PeyeonScript as eyeon

fu = eyeon.scriptapp("Fusion")
comp = fu.NewComp()

mynoise = comp.FastNoise({ 'Detail': 1337 })

#Does not "work"
print mynoise['Detail']
print mynoise.Detail
print mynoise.Detail.GetAttrs()

How do i get a value from a tool, i can't figure it out ?

Handling Source Footage

Tue, 30 Jun 2009 10:12:47 +0000

hey all
anyone know of a handy script, or even some hidden functionality in DF itself, to add footage into a flow from a remote location and automatically have it cache to a local temp folder?

Cordinates From A Tool

Thu, 25 Jun 2009 22:19:29 +0000

I can't get this to work with PeyeonScript (it prints the cordination of a selected tool):

Normal working script:

flow = comp.CurrentFrame.FlowView
for i, t in comp:GetToolList(true) do
	print (flow:GetPos(t))

end

PeyeonScript not working:

import PeyeonScript as eyeon

fu = eyeon.scriptapp("Fusion")
comp = fu.GetCurrentComp()
flow = comp.CurrentFrame.FlowView
t = comp.GetToolList(True)[1.0]
print flow.GetPos(t)

I get an error saying:

---
File: PeyeonScript.cpp
Line: 434
Condition: False
Multiple Returns
---

I have tried this in Fusion 5.3 build 55 and Fusion 6, with Python 2.5.

* Btw, Anyone know how to get the cordinates of the Mouse Cursor in the FlowView ?

Precise Color Selection For Object Id

Wed, 24 Jun 2009 11:24:41 +0000

Hi,

I'm looking to make a tool (script/macro) which can select a precise rgb value and convert it to alpha.

The idea is to render from Maya a pass which contains several precise rgb code without antialiasing and be able to select each color by entering its rgb code.

I don't know if someone has already done that, but it can be interesting because you can have many object in only one pass.

I tried with the custom tool but obviously I need more knowledge about scripting/expression that I have right now.

Thanks for your help

Hos Pixel Mapper Plug-in Update

Mon, 22 Jun 2009 14:20:57 +0000

Hey folks,

here's an update to the HoS_PixelMapper plug-in, in case anyone is using it.

http://www.svenneve.com/?p=247

Next update will add the ability to have a mirror mode along the black, duplcate and wrap edge modes.

Fuse Graident Control

Sun, 07 Jun 2009 11:05:11 +0000

Hey,

I want to query the colour at a particular position on a gradient control.

Actually, is there any documentation or examples of using a gradient control in a fuse? I can get one to appear, but not get any meaningful values from it.

Cheers,

Gradient Control In Fuse

Fri, 05 Jun 2009 17:56:05 +0000

Hey,

I have added a gradient contol to my fuse script:

	InR = self:AddInput("grad", "grad", {
		LINKID_DataType = "Gradient",
		INPID_InputControl = "GradientControl",
		INP_Integer = true,
		INP_Default = 1.0,
		ICD_Width = 1.0,
		})

Which apears no probs. Now, I need to query what the color value of the gradient is at a point. Eg, it's a gradient from black to white, the middle point (say .5 if it's a normalised value) would be grey.

Any ideas?

I just read:
http://www.pigsfly.com/forums/index.php?sh...071&hl=fuse
Which didn't fill me with confidance. Surly if it's a documented feature, it can acutally be used!

Cheers,

Lua Cross Product?

Wed, 27 May 2009 14:04:58 +0000

Does anyone know if there's a cross product function in Fusions scripting (for a prototyping Fuse)

I can't seem to find any, i found some info on the lua-users wiki (http://lua-users.org/wiki/PointAndComplex), but it seems i need to import a classes system and overload the default operators, not sure this is possible (or that i understand it for that matter.)

Anyone ever run into this before and has some experience with it?

Hos Pixel Mapper

Wed, 27 May 2009 13:35:17 +0000

This is what i have been working on this weekend, trying to figure out the SDK and subsampling, learning it by creating a plug-in that duplicates and adds some features to the Deep Pixel Texture plugin

Hope someone has some use for it, despite it being 'somewhat' obsolete

Maya 2dmvtoxik Render Pass To Rsmb Normalized Pass Plug-in

Wed, 13 May 2009 22:29:15 +0000

Here's a link to our Maya 2D Motion Vector (2dMVToxik) to ReelSmart Motion Blur plug-in.

Basically it normalizes the new 2d Motion Vector passes that Maya since version 2009 supports, making the use for La Maison's lm2Dmv obsolete.

Bug In Copy To Clipboard?

Thu, 07 May 2009 23:10:09 +0000

heyho,

if i do

pasting = comp:Copy(comp:GetToolList())

dump(fusion:GetClipboard())

it seems that fusion doesn't copy all tools to the clipboard. from my test it does not copy:

3d camera
3d projector
all particles tools

is this a bug or did i something the wrong way?

(copying the tools with ctrl+c and the pasting/dumping per script works correct)

Import/merge A .setting Or .comp File Into Another Comp?

Fri, 17 Apr 2009 09:27:19 +0000

Hi,

Scripting against an interactive session of Fusion, I can:

-Opened filehandle and read .setting file in as text
-eyeon.setclipboard to this text
-clear the current selection through the FlowView
-comp:Paste()
-comp:GetToolList(true) to retrieve the nodes just pasted in
-connect these nodes into my comp as needed

Is there any way to achieve the same result when scripting against RenderNode or ConsoleSlave. As far as I can tell attempting to access FlowView or Comp:Paste() without a GUI causes Fusion to crash. (Admittedly, it makes sense that these are unavailable. )

We are trying to make Groups of nodes for per-shot Color Corrections that we can dynamically drop into script-controlled Renders on the farm.

Any suggestions you can make would be much appreciated!

Thanks,
Paul Hudson
