If I’m happy with a procedural mask from smoothness, and I have UVs laid out, why am I getting textures from mask that look sort of correct but are full of dark polygon-shaped artifacts?
It seems to be related to decimation master not preserving a good enough approximation of the original UV layout in the reduced polygon set.
If I re-UV master the problem is much better. I was hoping not to have to do that, though.
Do you have pictures of the problem/UVs?
Screenshots please, so we can see for ourselves.
