Some of the texture painting's not perfect but in the end I was pretty happy with how the rig turned out. I have IK/FK switching on arms and legs, free/fixed hip choice, stretchy IK body with volume preservation and a nice B-bone torso, as well as clavicle deformers to keep the chest shape. On the hands I have palm fan controls and finger spread/fist controls as well as individual finger curls. Not too bad for half a days rigging and weighting.
Shape keys yet to come, only the eye controls are done for the face so far. Not sure if I'll bother with custom bones as I know the rig inside out and spent a while sorting out layers. Sadly the 32-bit PC in the studio can't cope with deep shadow buffers and hair without running out of RAM very quickly.
