"If I get white eyeballs the whole eye, iris and pupil seem to be covered up by the white" I know he has all 4 materials. The sentence above demonstrates that. The naming has him confused. Not his fault, the names are ambiguous. He is thinking that Eyeball is a part of the main orb, when it is not. I would think Eyeball would be done very similar to a clear sheet of glass. I get your frustration and why you deleted it. I am thinking that even if the method is different, a result like that in Poser should be possible and the reflective layer over the eyes be retained. If Carrara cannot do this, deleting the material makes sense.
