[Feature Request] UV islands, merge small clusters to neighbouring islands

[kwhali]

Automap UV feature is fantastic, very impressive results in testing. Only issue similar to other automap softwares is small islands, sometimes these are single triangles.

This usually seems to be because algorithm does not take into account size, only other metrics like angles? A min triangle or cluster radius would help. This could be separate from automap and just another uv tool that looks over existing seams/islands and merges/welds small island to neighbouring ones.

This is useful for avoid many islands on small noisy areas of mesh. Maybe it will need some cuts and islands in areas like this, however main advantage of automatic uv feature for me is making UV islands of the bigger broader shapes/volumes. Provides a good starting point. Presently either do manually or have to cleanup hundreds of islands. One mesh have 3k islands but only about 200-500 are reasonable size the rest need to be removed/merged.

 

EDIT, sorry just notice on mobile there is feature request section, could this thread be relocated there please? http://3dcoat.com/forum/index.php?/forum/14-feature-requests/
