I agree with Sean. I'm new to all of this, and there seem to be two key steps left out, one being that Traceable needs to be turned off on the Cornea, and that falloff was needed when moving the area of the iris and pupil back into the eye. But likewise, I'm not complaining that it's a failure on the tutorials fault, it's a very good tutorial. I'd like to see a more realistic iris though that still is UV mapped.

Thanks for the tutorial!

Alright, I answered my own question, ironically from the Pixar Eyes tutorial. I had to de-select the 'Traceable' button under the 'Links and Pipeline' buttons section for the cornea material. Once done, it rendered beautifully. Thanks for this really well done tutorial!

I am new to Blender so I stumbled a bit around the part where the iris is to be sunk into the main body of the eye. The tutorial was a bit confusing as it appeared that I was supposed to use a straight grab and move for the iris but in further pictures of the mesh displaying the cornea, it was apparent that it is necessary to use proportional falloff. I am not complaining at all, I just wanted to give a perspective from someone who is just starting but had some trouble with the tutorial.

Thanks again!

Excellent tutorial, but it will not render for me.

After finishing the tutorial and rendering, the eyeball is just black. I have a light placed in front of the eye. I have even tried the .blend example with the same result. I noticed that if I remove the cornea, the eyeball will render and looks beautiful but I suspect is not as shiny as with the cornea. The preview on the materials buttons shows the cornea material to be transparent. What am I doing wrong? I've spent a lot of time trying to fingure it out.

That eyeball would be useful for a cartoon feel, but I've yet to see a photorealistic eyeball created in Blender.

Check out Alex Alvarez's Gnomon Workshop tutorial on creating believable eyes. It's done in Maya, but there's (theoretically) nothing about it that couldn't be replicated with Blender. I'm trying to figure out the details of how it translates over (especially with regard to materials). I'll post a tutorial in the wiki if I get it all figured out.

@Streep
After selecting the proportional editing control, grab (G) and use pageup and pagedown to alter the circle of influence.

I just did an eye using this tutorial, its lovely i must say.

Try rolling your mouse wheel while you're moving the verts.

Hi,
Just starting out with blender and 3D modeling, so this tutorial is like gold.
One question though…
How do I adjust the circle of influence on the proportional editing controls? I see a circle, but it's about the size of the initial sphere. Am I missing something.
Thanks again for the tutorial.
