Creature masks with jaw operated mouths
I have seen creature masks with jaw operated mouths. The opening jaw pulls a cable that activates a upper lip movement.
I have tried this in the past and failed. I placed the hinge point of the mouth too far in front.
The boar man from the 90's Island of Doctor Moreau is a working example of what I am looking to make.
Has anyone else tried this? What were your results?
