Yogru FaceRig experiment

Yogru is a face rigging exploration project. Focus was drawn to solving a challenge of eyelids working with ellipsoidal eyeballs. The main concerns were clipping and range of motion.
My first iteration relied on blendshape driven key system which was scraped in a favour of point on surface joint system allowing greater accuracy and flexibility.
The system features 46 joints per eyelid each driven with a corresponding point on surface node. I have used Python to partially automate the creation of the node structure and connections. The joints position can be also controlled individually but are all hooked to a single master eyelid controller.
The rest of the rig is fairly rudimentary but I have learned a great deal about blend shapes, utility nodes and it was a great opportunity to brush up a little bit on Python again.
