I'm trying to make clothes for Manuel Bastioni generated meshes. So I can parent a mesh to an armature and it keeps its transformation. However, as soon as choose a specific bone, the mesh undergoes undesired translations and rotations. Here it is before parenting to a bone, but already parented to the armature:
I can painstakingly replace the mesh afterwards but it's undergone too much transform to make it a matter of a couple of rotations.
N.B.: I cleared all position and rotation on the original mesh before parenting and it was in perfect position.
Any idea why it moves and how I can stop this from happening?
