I’ve got a few different 2d face images (smiling, sad, frowning, etc) that i want to animate on a sphere. Is there a way to do this with drivers that would allow me to use a slider on an armature rig and set a key for each of the images? I’ve had a few goes at trying to code it with python however i can’t seem to wrap my brain around it.
Is there a reason why you are using the cycles renderer since this can be dne in the blender internal by keyframing which textures are active/non active in the materials texture slots. The change in texture can then be driven by whatever you want.
You can make copies of the head, so you have many heads each with a different texture.
You can then swap between them by having only one at the correct size, while all the others are scaled to 0x0x0 so they are invisible.
