Dears,
I’m using V.ray on 3ds max 2023 with ACEScg but colors too saturated, so how I can get correct picked color in acescg ? and please I’m not technical so talk with me in simple statements and clear steps.
** when I change Display Correction to Gamma 2.2 and look at “VRayDiffuseFilter”, color become correct, so I don’t know what I can do to get correct colors in ACEScg workflow **
Final Result :
with my best wishes for success 
Any Idea Please 
Hi, I am not a MAX and neither a VRAY user.
But, it looks like that there are two things happening:
A non ACES gamma 2.2 view transform looks simply different to the ACES RRT&ODT or any other view transform.
The 3D-scene RGB value of 1 is mapped to 0.81198 in the sRGB ODT. I wrote a bit about this topic on my blog (1.2. Linear Ramps – Brylka – TooDee – PanicPost)
Blender for example does not convert picked color values from sRGB to ACEScg. You have to do this by yourself. Otherwise you might end up with too saturated colours. I linked another article from my blog directly here on ACESCentral.com (Understanding Gamut with ACES & Blender)
I hope this helps.
thanks for replay
i used ACEScg Color Value and it’s become correct result so you mean the problem in convert image inside V.ray because i can’t do anything in this process, you can read doc :

Based on the above, i have two question :
