I’m using Blender 2.62, and I’ve found some strange behaviour with animations. I’m also a noob at this, so it might be that I’m just doing something stupid.
In any case, I’ve imported a model that is only two human arms perfectly mirrored. I then created an armature with x-axis mirror on. I then parented the armature to the mesh with empty groups. Directly after doing this I go into pose mode, and for some reason some of the vertices move around when rotating the bones. I would expect that because no vertices are assigned to any vertex groups, the mesh should not be influenced by the bone rotation at all (or this is how it worked in previous versions). Is there something I’m missing?
I can recreate this behaviour consistently but I cannot figure out how to fix it. I’ve also double checked all the vertex groups to see if any verts are accidentally included, but in edit mode, not a single vert is in a vertex group. I’m really stumped by this and would appreciate some help very much.
