I have been studying techniques for creating cloth rigs recently and I hit a snag with what looks to be the commonly agreed upon solution for cloth that must move with bones, which is hooking certain vertices of the cloth to the bones of the armature.
What happens is my hooked vertices get disproportionately stretched and the rest of the mesh geometry doesn't follow realistically.
Here is a very simplified illustration of the problem (1 mesh with 3 verts hooked to bones):
In this example simple edges are used, but extruding to add volume to the cloth doesn't improve it, so I don't think that's the problem. Also, I first observed this on planar cloth meshes.
Is this a problem with my settings (I've tried many configurations), or a bug, or ...what?
