From what I've seen, BBeye has combined V4's sclera, iris and pupil into one material. And instead of a cornea andeyesurface material there is a separate "cover". Getting the cornea/eyesurface to play nice was hard for most to grasp so most made "eyesurface" invisible and put reflection on the cornea. But,, this makes it hard to get a smooth transition between sclera and cornea with reflection.BB's "cover" is good for reflections. And it can be shifted unlike V4's "eyesurface".

The other reason is the refraction of lens issue and scale and artifacts between the surfaces which is another long winded story. Nobody seems to mess with it anymore. Don't know if there are morphs for BBeye, though. iris size, dilate, etc..

 

 

"overload"..LOL yup. got that tshirt
