Hi, I am trying to make the textures on the R23 toon rig template to Arnold textures, but there seems to be a problem with alphas that I can't get my head around. There is one singular eyeball mesh that has two rigged textures on it that can be driven via Xpresso. I want to keep that functionality, so I have to adapt to the way the textures are laid out in the rig.
The pupil is on top of the iris, so there would need to be an alpha on the pupil material that lets the iris material come through it. I have tried using the cutout opacity and opaque settings to no success so far. Any ideas?
I have attached the setup as a screenshot
