I’ve run a 20 million tris mesh through ZB to clean up, now have a ZRemeshed Subtool which won’t unwrap in UV Master, read that messed up polys hiding inside (non-manifold geometry) can explain this behavior, to use AutoGroup to isolate the manifold geo from the non-manifold, then zap each Polygroup individually. In my case AutoGroup produces but a single Polygroup, but Split reveals 170+ Subtools with messed up polys. I’d like to avoid setting anything individually for all these, tried simply selecting the main mesh Subtool and running UV Master, alas without success. It gets stuck uncutting the the first of 13 parts. Any thoughts how best to address this mess? Thanks in advance.
