Problem with ft-UVPass // can't get a clean UV map to work
on Aug 21, 2018 at 2:10:24 am

Hi everyone,

I'm having big trouble with the free ft-UVPass plugin.
Eventually I'll have to re-texture 42 flag animation inside After Effects (deadline is tight so it's not feasible to render 42 animations from Cinema 4D).

Now I've put out a still image from the Material UVW pass from Cinema 4D and no matter what I do I can't get the texture in AE to map properly.
Even with just something simple like a primitive plane as a model in CInema 4D.

Please find my project file under the link below, hopefully someone knows how to tackle this.
Many thanks in advance!

I wasn't able to load the AE project for some reason (different version perhaps). But the usual gotcha for most people is that you have to interpret the UV pass element in the project panel and go to the Color Management tab and choose preserve RGB. You also must work in a 16 bit or higher comp.

[Steve Bentley] "I wasn't able to load the AE project for some reason (different version perhaps). But the usual gotcha for most people is that you have to interpret the UV pass element in the project panel and go to the Color Management tab and choose preserve RGB."

I opened the project, and this is exactly the problem.

The color management engine attempts to preserve the appearance of color across spaces by transforming the color values from the source space to the working space. But UV material passes contain data, not image; it's not the appearance of color, but rather the literal values that we need. "Preserve RGB" tells the color management engine to keep the values (even though the colors will not "look" wrong). Bad for an image pass, but critical for a data pass.
