Chaos Corona for 3ds Max > [Max] I need help!
OCIO / ACEScg
mrsacan:
Hi guys
I'm used to work on gamma 2.2 workflow and I don't use OCIO. Recently I installed 3ds Max 2025 and it says gamma 2.2 setting is legacy so I wanted to start work with OCIO (because legacy usually means at some point it's going to become obsolete and not supported), but first of all I can't get colors right (corona bitmap).
I attached some screenshots. I tried different color spaces, but it's always different.
I checked some old topics and this link : https://support.chaos.com/hc/en-us/articles/20474209561617-Color-Color-space-and-Color-Management-Basics
But I didn't able to see a solution/workflow.
I can still use gamma workflow and do my job, but I want to learn how can I setup OCIO / ACEScg correctly. Is it possible or not etc.

Hi,
Which version of Corona are you using?
There were related fixes which should be in latest Corona 12 Update 2 release candidate. If possible, please try with it.
I suppose your veneer texture has nothing special and should be with sRGB primaries.
maru:
RGB primaries set to "auto" should give you the correct results.

My last screenshot is set to auto, maybe I'm missing something else in another screen/option?
