How can I remove all zero weights from skin?
Like on the picture.


I’m currently selecting vertices in Edit Mode, select vertex group and press Remove. This is impossible to make for all vertices… But is there some automatic way? I tried to select all verts and press “Clean”. It does not do this job. All zero verts are still there.
I cannot just leave zero weights in this skin, I need to remove them…

In the weight paint mode tools, you should be able to choose “Clean”, and then “All Groups” for the subset in the options panel.

Thank you! Awesome! By default there was “Active Group”, not “All Groups”. “All Groups” works just as I need!
