ACES display problems

[Jonathan Lutjens]

I've been searching for a solution to this problem and haven't found anything. I'm hoping someone here can help. Pics are attached.

Working on a video and the setup is as follows:

-Footage from Alexa 35 (ProRes 4444)

-Renders from C4D octane (working in sRGB linear, octane set to ACES cg, exporting ACES cg EXRs)

-occasional sRGB images

-Compositing in AE set to ACEScg, 32-bit

-Windows 10 pro, latest version of AE

I can't figure out why different comps are showing color differently. The main composition where I'm animating looks correct (or at least the way we want it to look). The Main composition, within which this "scene" comp sits looks overly dark and contrasted. The pre-comp used inside of the animation pre-comp also looks overly contrasted. I can't get any settings to change this. Turning off 3D cameras, changing bit depth, interpreting footage differently.  Anyone else experiencing this? Do I have some setting somewhere incorrect? Is there an issue with my card (RTX 3080Ti)?

Thanks for the feedback!

It is possible you are hitting a known (and soon to be fixed) bug in the intial OCIO implementation.
Could you try this quick workaround and see if it resolves the color difference between Comps?

For each Comp in your Project, go to the Composition Panel and switch the Display Color Space to None, and then switch it back to the setting you intended.

Does this resolve the color difference issue?

Thanks, Paul. Yes that did fix the display problem!

Hopefully the next update will get that sorted out.

I'm glad we solved it!

It's already fixed in the current AE Beta release. Will be shipping soon.
