Helo
I've downloaded this head and imported it in my blender program. I made some changes (removed the body) and gave the head colors. Everything is great, but when I render the image, I get unknown distortions especially in the eyes!

Here you see the head in blender when I edit it. The eyes are perfekt: https://www.dropbox.com/s/cibfyqtaxtj5suj/screen.png
But when I render the image, I get this: https://www.dropbox.com/s/qc0rtmblaczpr0e/untitled.png

Now I discovered this: When I change the color of the Iris from "surface" to "halo" I see this strange model in blender: https://www.dropbox.com/s/09fbayik3ag44na/screen_halo.png
There are only points and even points of the body which i removed already! What does this mean? And why is this effect only working with the color of Iris?

Can somebody explain me that? Thx alot in advance!!

Could you check it out in Edit Mode in Wireframe? Do a Select all in Vertex mode and do a screen capture. Just wondering if you have stray points.
