I’ve played bit more and by editing the positioning of the guide bones, and seems to be getting better results now.
I’m just confused as to where the guide-bone ends needs to be on the eye area… on the eyelid geometry or outside? Same goes for lips, do the guide-bones need to be offset and not directly on the lip edge-loops and do they need to be increased in size according to the thickness of the lips or irrelevant?
The correct placement of the Skull 1 2 3 bones?
For the eyebrows, do you need to create shapekeys afterwards? You mention “tick deform” on your docs should you wish to use bones deformation, where do I find this?
On the eyelid upper and lower controls, should one use rotate or translate when animating these?
