Leg Rigging Tutorial

Joints

The first part of the process was to place all the joints creating the beginning of our skeletal structure. This joints are all points at which the final creation is posable. The bone indicates the connection between each joint. Also when creating the skeleton the joints all need to be orientated to mayas axis for easier animation.
