Character Rig for my final artwork at my Higher Education. Free model by Andrea Patrik on Sketchfab.
This rig has different advanced techniques to make it look more natural to the eye, including: strechy bones for the face, Ik/Fk switch controllers with swivel, parameter wiring for twist-roll in arms and wrists and spine, and custom attributes for the feet using reaction manager.
