Corona 12 Update 1 (Hotfix 1), 3ds Max 2025
The problem still exists, are there any possible solutions?
I'm attaching a detailed example:
New empty scene in OCIO color mode, neutral-lut.png file loaded as raw placed into the scene as environment map in screen mode.

As you can see, this is not just a lack of saturation, it is a color distortion, especially strong in the red channel.
