Ok, this is probably a stupid question, seeing as noone else seems to be having this issue, but nonetheless, here is my issue.
I’m weight painting a tabard (a sort of medieval shirt with no sides) I didnt get very far into it at all before weight paint started screwing with me. FYI, the FIRST thing I did in weight paint was set all vertices on all bones to zero, so it isn’t group conflict. Anyway, when I try to rotate the shoulder bone on the y axis, (using r,y to avoid errors) the damned thing rotates on the x axis anyway. WTF, blender? So my question is : How do I keep the bone from rotating in ways that I’m not telling it to?
