Guys, let me know which iris or cornea shapes you'd prefer. It's very easy to change this, and if necessary, we could have have a variety of shapes via morphs to accommodate different types of eye shaders. I don't have much time now, but I can explain to you in detail why I made the shape the way it is.

Because I work with two different resolutions for the mesh, it will be quite tricky to get rid of that sharp edge, though, no matter what the shape. Question: is it really necessary to use a specular on the iris? If only diffuse were used we wouldn't have that problematic highlight there.

Edit: By the way, if at any time someone comes up with better eyes, it should be very easy to drop them in via geometry switching (lesbentley, correct me if I'm wrong).

-- I'm not mad at you, just Westphalian.
