The human face is very organic and when using a normal map, things with animation get a little tricky. I’m trying to animate a blink with an eye where this wrinkles appear on the face as the eye closes. Not just the eye, but this wrinkles are needed for other expressions as well. Something like this example - https://www.youtube.com/watch?v=mc7ADD4b8_0
Any ideas how this so called "animated normal maps" can be accomplished with Blender, because in the UV's I know to work only with still images?
