Anyone know a foolproof method of doing animated 2d eyes/mouth? I figure shape keying a bunch of planes in Blender of various face/eye states would work, with flipping them a millimeter in front of an otherwise blank face. It works perfectly fine in Blender, but VRchat it's a little fucky since it's trying to interpolate between the 0->1 state of the shape key instead of being instant.

Only doing this because I got a low-poly model I'm doing, and it seemed appropriate to give the illusion of an animated texture for a face instead of modeling it all in.
