Using some MEL based scripting I have just started creating my leg rig. Please check it out.
The difficulty of this rig, with regards to the feet, is the use of bipdeal rigging methods on a digigrade (?!) leg... So... a human leg rigging method on a leg with a mix of quad and biped features.
See you later, check back for more Rigging fun times in about... well... TONIGHT!
