Can anyone tell me what's causing the dark red shadows on Viki's eye (the on on  the left part of the image).  I loaded my character, used 2 lights, one infinite, one diffuse, and used VSS.  I rendered it and I got that deep eye shadow from that angle.  However I went to face came, rendered the eye again without changing anything and from head on, the shadow was gone.

Here's my sclera shader if that helps.

It seems to me that it's is a simple case of the eyeball not fitting the eye socket: the white edge is the outer curve of the eyeball, and the red is the inner surface of the eye socket. I could be wrong though.

I would agree with IsaoShi.  It does look like the inner eye socket prominently visible..

PS:  I would suggest checking the horizontal alignment of the eyeballs in a head-on shot. Usually a small x-axis adjustment to each eye (not always the same amount each side) is enough to fix the problem, although sometimes the eyeballs need to be moved forward a fraction too (and I think these probably do).

Incorrect translation is almost always the cause of the eyes appearing to the viewer to point in different directions when rotated sideways as a pair (or individually by the same angle). It can also be caused by incorrect morphing of the eye position, resulting in the eyeballs no longer rotating about their proper axis (see lesbentley's recent post on this).

Yeah I saw that post.  I just looked at the sense again in smooth lined mode and yeap, the eyes aren't in the right spot.  Now I gotta go find that post and fix her up.

Thanks guys.  Tweaking positions are a lot easier than having to fix texture nodes sometimes.  ;)

I'm actually glad I found this problem.  After trying to get the eyes in the right X,Y,Z positions I noticed that for some reason the morph I used did really freaky things to her cornea and gave them a bulge out a ton.  Now I gotta figure out the best way to fix them.

 Thanks Winterclaw. I have run into this myself-now I know the fix!

 Hey Winterclaw

 I just bought several morph characters and have been loading them into the same V4.2- I ran into the eye misfit problem again- then I looked at right and left eye parameters-and injection channels- Daz and Community- there were three different character morphs set at 1.0- when I zeroed them the eyes lined up. The other problem was that the irises were tiny-very strange- all fixed when I zeroed the eye morphs
