Thanks for these ideas, but before I proceed with them I've been looking at the eyes again. The texture that ships with the model has a good reflection of a window or something and the lacrimal's have highlights too. Now, my question: why then does my render not show this while I can see it clearly in my preview?! I can see how the spotlight I've placed causes the highlights in her eyes that you can see but why do the reflections from the texture file not show through?!

Wow, the eyes sure are complicated but are, in my opinion, the most important part to get right.

Anyway, anyone have any ideas on these things?
