See I have gotten something similar done using modifiers.
But what I couldnt think of was how would you be able to, using these modifiers, put together a face rig for an animatable character?
For instance, lets say you for some reason wanted to make the character raise its brow like the rock’s meme (because why wouldnt you).
I cant picture how you would rig a face that has ‘essentially’ (but not truly since were offsetting it) only a 2D depth to its mesh.
