Quadru-Rig Automated Rigging Tool
Over the course of a number of projects, I developed a tool in Maya using Python to automate a large chunk of the process of rigging quadruped characters. With a few clicks, a user can have a set of four limbs, each named according to a naming convention, and complete with IKs, curve controls, as well as toe-pivot and ankle roll attributes. They can also create a spine setup from joints, and use it as a naming tool to name joint chains.
You can download and use the tool in it’s current state HERE:
