I can see how Bay Raitt must of gone crazy building the facial network for Gollum. Looking at the FACS (facial action coding system) action units of the upper face and its corresponding corrective targets made me go a little doolally! – First off even though the algorithm of driving the correction is a simple sort issue – the order in which they driven is a little un nerving:
On the left are the base targets – the action units. From left to right the orange nodes are the corrective targets needed – you have to build them in this order as for target “1 + 2 + 4 + 5” you need “1+4+2”, “1+4+5” and “2+4+5” then “1+4”, “4+5”!!
Dont get me started on how many you need to link to the mouth and well the mouth targets themselves!!!
