I’m working on this portrait of a person and I’m having issues with the eyes, not because I don’t know how eyes are shaped but because of the material settings. I have created the eyeball and made a small valley for the iris/pupil. Then created a sphere around the eyeball to act as a lens, the picture below is just the eye lens using a glass material. There is a sun lamp that realistically would create a highlight in the eye but the glass material won’t show it. It’s also killing the dark pupil and the values in the iris.
Is there some way to create a realistic lens for the eye, something that doesn’t darken any part of the eye just is very reflective? I suppose it would act a lot like a mirror just not opaque?
