In the latest version of d5 which i updated, I have same 3d model duplicated and i applied same material for both but 1 model’s color is off(Lighter faded material). Looks like a bug. I tried doing all the things i can. Looks like this happens for fabric materials.
You mean these two, right? It’s weird. Did you import the model or sync it? Can you send the 2 curtains model to us for troubleshooting? If you can reproduce this issue and record a video, it will help a lot.
