I might have sent a wrong screenshot at some point, and did not test it enough (like at all), see if you can update the material loop:
Looking at this now, it may not be the best way to handle it. But again, I’m not sure what you’re going to use it for so it’s hard to advise, really. If I find the time at the end of the week, I can have a deeper look at this and try to replicate something similar to your picture.
Is this what you want or is this just a refence image?
