Colors are off when appliying same material for 2 models

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.

Look at the curtain colors from here

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.
