I have a cube scene for the sake of example, but in my production, I use textures for the facial expressions of my character. The problem is, I don't know of an efficient way to animate the changing of a texture.
Blender insists that I cannot keyframe the changing of an image.
Previously I have been naming all my files sequentially and animating the sequence, but that is severely impractical. Is there a better way to animate the changing of textures in cycles?
Thanks!
