That kind of rigging was new to me i used kinda old method of morphing in max (facial morphing - expresions), but I found it limited of some reason, cant get much controls (need to model alot morph targets :/) so Im looking for new methods of face rigging, and I found this (Your) interesting and usefull method. But at the moment of your screens and talk i cant get , even stetup these muscles, or however u call rigg. Just technicaly intersting how u do it on max.
Looking forward for your tut!
