The rig is set up in several components, divided by the limbs, and aims to create a fully functional body rig before the modeler is done creating a clean topology. The components make use of IK, FK and Spline-IK systems with blending where necessary. Some python code is shared to speed up some of these workflows. Tools that are not part of the original Maya tool-set will be used to create controls and help out with skinning the basic blockout mesh. This will then become the base information used in the final mesh, where a second phase of rigging starts: adding the extra detail controls on the character. The end-result contains a rig that is easy to use for an animator and which can be directly used in a game engine.
