How do you animate the face textures of your models? Like how you make the human's face texture blink. Do you have a facial expressions sheet, or do you change the texture or something?

I’ve used all of the above before depending on how much time I have.

Geometry swapping with different textures.

Each head geometry has a texture with a slightly different expression. Its the fastest to do on the fly for short, quick expression changes with little front end setup.

In action:

Most efficient method: Texture scrolling/snapping

which does use expression sheets V

I’ve only begun to use this, as this method takes a bit more time to set up (its shader node dependent as it involves keying texture node offset values to a controller. Works great in the long run with as many expressions as you want to make. I’ve yet to implement it into my main rig.

Note that all of my Undertale character animations use the first method with the exception of Omega Flowey which uses the later. See the videos in full on my Youtube channel!

Thanks for asking!
