Lens Distortion STMap
Posted: Tue Apr 10, 2018 4:31 pm
Hi, I'm having trouble trying to figure out a method to share Lens Distortion values between Fusion and Nuke.
I'm a tracking artist. I can track a shot in 3DEqualizer, export the lens_distortion data from 3DE to Fusion and have it work. But I need to be able to create distortion maps (STMaps in Nuke) to share between the programs so that my Nuke users can undistort / redistort their elements to match what's being done in Fusion.
Fusion has an option to export a distortion map in the lensDistort node. But it wants to export a swirl. I need it to export a ramped UV style red/green/yellow exr image instead that contains the same values so we can use it as an STMap in nuke.
I've messed around with the texture nodes, and displacement nodes, and trying to add expressions in channels but I don't know enough about Fusion to make this work properly. And nothing I've found online seems to work.
Any ideas / advice / examples would be greatly appreciated. FWIW I'm using the Free version of Fusion9. Thanks everyone.
