I got impressed by the Claytons face animation videos you linked earlier. I think he used blendshapes in that rig.
I’m going for more realistic animation with this one. So, i’ll try to work more to make the edge flow follow the facial features.
I’m not sure exactly what you meant by the “concentric ripple layout”.
This one is more experimental personal project for practice so i don’t have a deadline nor clear direction where to go.
I built a ribbon based mouth rig for other school project earlier. It has worked pretty well so far. I might try it with this one and compare with the blendshape method when i get some good topology done.
