That all sounds cool, right? It would be if the iris can be fixed.  The iris has a hard edge stairstep-like edge. This is a problem, imho, and it makes the eye look more like a stuff animal teddy bear eye than a realistic human eye.  I've already made a few attempts to morph the iris to get rid of the stairstep. So far I haven't come up with a better shape.  The iris is actually not attached to the eyeball at all. It's like a prop inside the eye. Make sense?

Yeah, I'd have to partially recant my UV statement from earlier, because it seems that for all the good they did with the UV's, they made up for it with the eyes.
"sclera" seems to be a continuation of "eye surface", and it doesn't line up particularly well. Why they did it that way, I have no idea, but it must have made sense to someone. Although Sclera is inside of Eye Surface.
And Sclera, which seems like it should connect to Iris, actually obscures the outer edge of Iris, which is why you get that hard edge.
I'd imagine this could be solved with morphing, but that might not create such a good result - I suspect the idea was to necessitate the purchase of "reveal the Iris edges" transmaps for the sclera.....
Of course, as long as the geometry remains the same, you can alter the UV's, reload it in Poser as OBJ, and use the original skeleton to fix that, and still retain the MT's. I think.
