I am having some very frustrating issues. I modeled a perfect eyeball, that I am very proud of. I created all the materials, and then attempted to render it. None of the materials show up. The shine and reflections show, but no material. If I take those same materials, and put them on another object, they show up just fine. The object is renderable, the materials show in the viewport. I was wondering if there was a fix other than deleting the eye and starting over.
