The material colors in the corona vfb do not match the color of the actual material. If I try to change the color management from OCIO to Gamma workflow, 3ds Max crashes. Why is the material in the vfb not matching the actual color it is supposed to be and how do I fix this? I also tried a final production render and the color does not match using that either. I have tried it with ACIS OT turned on and off and this makes no diference. What am I missing?
When rendered in Corona, materials are affected by scene lighting, bounced light, reflections, etc. So a texture will almost never look the same in the Windows picture viewer / Photoshop as when rendered with Corona. If I misunderstood your problem, can you please share some images showing the original textures and how they look when rendered?
Also, 3ds Max shouldn’t crash when switching between color management modes, but unfortunately I don’t think it’s related to Corona. Perhaps reinstalling 3ds Max would help.
