Has anyone worked out how to use the distortion, calculated by Syntheyes, with the Fusion Lens Distortion?

[PeKi7i]

there is macro on vfxpedia

[PeKi7i]

or script for lensdistortion tool

[Dietmar]

Thanks.
But I can't find a way to get an UV Distortion map out of Syntheye.

I've written a script that converts the Syntheyes distortion coefficient to a 3D Equalizer value (maybe that's what PeKi7i meant): http://www.vfxpedia....r_Syntheyes.zip
I hope Fusion gains Syntheyes support in the next version. After all, PFTrack has already been added. But maybe an email to requests@ eyeonline won't hurt :-)

I went the UV map route once as well. You need to create a UV map at the right size in Fusion and then replace your image sequence in Syntheyes with it. Export it as float and bring it back into Fusion... but it's a convoluted workflow, it needs the right settings for the Displace tool (which might break in proxy mode), needs special care if an undistorted image has a different size than the original plate et cetera...

Thanks, I will contact support for syntheyes support too!!

Tilt has a post with a graphic showing more info about his script here:

Just sent my request to Eyeon about SynthEyes

BTW - DigitalTutors has a SynthEyes/Fusion course that I've just watched which is pretty useful for getting up to speed on SynthEyes/Fusion integration.

He didn't use Fusion's fog for the shot, but rather a 2D EXR sequence, which seemed to give him a lot of control, but ... I'd be curious about using the fog tool (as he had a depth pass).

Some of the course objects are in Modo format, but the author was nice enough to convert them to Lightwave for me, and I expect he'd do the same for OBJ/3ds/etc.

Thanks, fore the tips!
I normally had been using the syntheye workflow. But saving the undistorted image sequences and distort them after compositing, is something I would like to avoid!
It is better to all the distortion stuff in one compositing without an extra "generation" of the material.

Hi... one very basic question (sorry!)  How do I use SynthEyes lens distortion script in Fusion?  I copied the script file in Utility folder under script.  I can see it when I go to Fusion / File / Script.  Now what?  Thanks.  Alkesh.

[Tilt]

It's a tool script so it goes into the Scripts\Tools folder. Then you need to right-click on a LensDistort node and select it from the scripts menu.

[Alkesh]

Thanks, Tilt.  So I moved the file to Tool folder.  Now I see it when I right click LensDistortion node under script.  But nothing happens when I select it.  Could it be the version of py in which the file was written vs the one I have in the machine as issue? I have Fusion 6.4 latest built (1111).

[Alkesh]

ps: I am running Py 2.7.

[Alkesh]

Also, I just noticed the following error in Console when I right click LensDistortion and try to select "LensDistort for Syntheyes.py" from script.  Not sure what it means:

Traceback (most recent call last):
File "<string>", line 1, in <module>
File "C:/Users/Public/Documents/eyeon/Fusion/Scripts/Tool/LensDistort for Syntheyes.py", line 61
print e
^

[Tilt]

It doesn't even pop up a dialog box? hm....

I'm running 2.7.1 myself.  I have no idea what that error might indicate. There *might* be a warning about "import math" when you first start the script but that doesn't abort the script and it won't show up again when you run it again.

You could try to replace "print e" (almost the last line in the script) with the word "pass" and then see what happens.

Can you check if you have also Python 3.1 installed and if your Preference->Script->Python is set to 2.7.

If something like print e is an error it looks as if python 3.x is used as the print statement was replaced with a print function (which needs brackets).

Cheers,
