yup, its Oct, so stop the body rigging…well, you can continue, but you can now start teh facial rig.
Facial rig requirements :
1 : The character is for an animated cartoon series (not really, but for the challenge, go with it) so he needs a well developed facial rig to allow for a range of motion, as well as cartoony expressions
2 : eyes : the eyes need a system put in place to allow for some pseudo sculpting by the artists, that is they can taper them, bulge them out, and such, but it still needs to deform correctly as he looks around
3 : All of this needs to work on top of what is already being done with the body rig.
