I made a simple model with multiple meshes. One of them is the head The rest is unimportant for this question. The model has one armature which is the parent of the meshes. All the vertices in the head mesh are in one vertex group which has the same name as the head bone. The head mesh has no Mirror modifier. I set the pivot of the head mesh and all the other parts to the middle of the head mesh. I used armature from the add human (metarig)
command. I applied all locations, scales and rotations. I have no idea what other detail I should supply.
Normally it looks like this:
However, when I try to rotate the head (not the neck, the head) it looks like this:
Can anyone help me on how to fix this, or should I actually rotate the neck?
