I'm actually not following this. Maybe it's too early for me, or maybe I'm just too distracted. ;-)
That last render above looks pretty good to my eyes. No pun intended...

So... are you saying you don't like them mapped that way, or you do?

Wow, I'm really not happy with how I mapped the eyes now.
You know, this is really strange and I can't explain it, but looking at earlier versions of Antonia I could have sworn both sets of eyes were mapped separately, so I had that in my head, and that's why I did it the way I did. Now I see they were both sharing one set of UVs. Major brain cramp there, I tell you...
How come nobody said anything about that? ;-)

I can, of course, redo that easily enough, or maybe Olaf could just substitute his original eyes in the geometry itself instead.
