This is a rig demo of my Mongrel character, which I've made a side project during my last year of my BA Course.

The main features:
Broken Hierarchy IK/FK spine
Local/global switches on Arms, Head and Tail
Non-flip IKs on the legs.
Custom Spring-like IK solution with overrides for the legs.
Automated IK/FK snapping on legs and arms.
IK/FK shoulders.
Blendable dynamic tail.
Muscle system (maya cMuscles).
