Erik Arrhenius shares Troglo AutoRig. A python driven script that can easily rig custom bipedal characters. Initially developed to supply rigged characters for the Troglobyte Studios Underdog Engine, the Troglo Autorig Tool can easily rig symmetrical and asymmetrical characters in any pose.
Troglo Autorig Tool can also create both digitigrade and plantigrade legs, save and load joint placements, provides IK’FK switches for animation, and can supply a simple proxy mesh for the character. Troglo Autorig Tool is available as freeware, and is compatible with maya versions 2011 to 2014. Check out Troglo Autorig Tool for Maya here.
