This is the rig I’ve created for biped characters. It’s a very useful tool to have around it is IK and FK rigged with controls for rolling the foot, bending the fingers, opening the mouth by moving the jaw. It saves an awful lot of time to have this on file to bring out for any characters. It certainly isn’t a one size fits all sort of thing, but it gives me a head start with character rigs.
