We begin by discussing the core concepts_of_skeleton creation: how to create joint chains and manage hierarchies, IK versus FK, and how to test behavior with a quick IK rig. We create Jester's skeleton in realtime, while explaining all of the required steps to ensure proper behavior down the road. With Jester's skeleton created, we now clean it up and prepare it for skinning and control rigs. At this point you will know everything you need to know in order to create skeletons for your own characters or creatures.
