Color Management in Max 2025 / Vray 7 : Missmatch between VFB and saved PNG/JPG

[mind_palace]

I am continuing to have issues with the colors in the VFB not matching the actual saved JPG/PNG. It looks to clearly be a color management issue. I have tried to do my due diligence in searching the forum but haven't found a solution.

• I am a general vray user. I do not "need" any specific color matching workflow or precision for my purposes, although I am happy to use one if it makes sense. I usually just rely on defaults. I DO need to be able to reliably save my renderings as images without a lot of post-production.
• I am using Vray 7 and Max 2025
• When I render, everything looks fine in the VFB which makes me thing there is no issue on the material side. As soon as I go to save a png or jpg, the image gets very dark, or very washed out. This looks to my eyes like a gamma issue.
• I have tried just about every combination of settings I can think of in both the VFB and in Max's Color Management dialog. Attached are screenshots of my default settings, and a comparison of the same image which looks fine in VFB but unusable as a png.

Thank you!

Have you tried enabling the "Save in image" option in the VFB display correction settings?

Appreciate the response 3DZver. That certainly helped. I'm still getting darker shadows in the png than the frame buffer but guessing that might be a symptom of the png just not holding as much data?

There's also an issue (already fixed in the latest stable builds) when using the 3ds Max Color Management Render Output Defaults. To get matching results, those options should be set to "No conversion" along with the VFB OCIO Layer's "Save in Image".

Great - that seems to have worked. Thank you both!
