I wanted to create a character with a body material that changes color that still has facial animation, So I followed this tutorial to make a transparent texture: duplicate mesh of the face, unwrap it, set up the nodes, then parent the mesh to the original body: https://www.youtube.com/watch?v=6ExiMqTk5mw&t=87s
however, when I tried to follow this tutorial using method 1, multiple different textures:https://www.youtube.com/watch?v=nmzAbeUDPUQ&t=25s I cannot get past even one mixrgb shader(in blender 3.30 I only see mixrgb when I go into the color dropdown to add nodes)
when I place the two transparent textures in the mixrgb the texture connected to color1 simply turns black. I have one open eye texture with color and one closed eye texture that is completely black.
is there any other technique for animating multiple transparent image textures in a single material, or animating multiple materials?
