so I was following tupper's tutorial to make a simple mmd port and in his example he had a bone that's under Head but it was in the located in the middle of the head, so he reparented all the hair bones to that center bone so he could do dynamic bone in Unity.
I currently have something like this where everything(hair, some accessories, eyes and teeth) is flat under Head and there isn't really any additional bone that's at the center of the head and free to make it a parent. Can I somehow create a new one? Maybe just duplicate the Head bone but without any children, put it under Head and reparent the head to that?
