Hello,I'm new to Anime Studio and I seem to have some problems with bone rigging. http://img405.imageshack.us/img405/869/p1cu0.jpg Everytime I move one of the arm bones upwards it disorts the body and makes my character look as if it has a hunchback.I've been trying to solve this problem but nothing...
