As some of you know, material utils is broken under bmesh… quite a simple fix to fix it… open up material utils python file ("\2.62\scripts\addons\space_view3d_materials_utils.py"), find all cases of “faces” and replace with “polygons” (without quotes)
Ive commented on the script page as a fix.
Hmm - I only see face and replaced it with polygon and it still works I think.
However it adds an UV-map to meshes without one every time I assign materials with it (I was wondering why my files where getting a lot bigger while I did only replace material.001+material.002+material.003 (and so on) with material).
it’s not broken, it has been fixed a long time ago. Are you sure you are using the latest version?
