Now see the thing is this, theres more to what I was going to add. Hats off to Kurt for his tute, although Ive not seen it, does it cover the parallel option in the blendshape editor?

This is a great way to create new character heads and utilize the old facial expressions without remodelling plus corrective shapes on joint deformation. I was going to cover some Zbrush too to add the extra ooomph to the facial shapes.

I think our own SM member, JHaydock has been the only person to witness this technique first hand in our studio whilst doing some work for us...

Cheers
