I played a role for rigging characters and props for this program . My main technical challenge for rigging was,that the characters and the props were modeled on a polygonal plane. I handled this by locking the attributes of props which could give them wrong bend and adding the controls in right position to give it correct bend. Many of the positions were also handled by switching the body part's positions.
