Hi again!

Now I completed the iris. It looks good when It's not fully closed, but when it is, the shadows are looking extremely strange? (The Dmap-resolution is greater in the pic with the closed iris)

The portal-Surface isn't good at all.. It's still looking wrong. But that is the best I was able to do scince now. I simply used the denfo-purewater shader and adjusted it a bit. I still need a good TUTORIAL for shaders and how to create them.
I think I can model things ok, but my shading-work isn't very well..
