Quote - I have a problem finding the right parameters for eyes to look "wet and shiny", and nearly the same problem for teeth. (you can click for higher rez, you'll see how unable I am to reach a "nice" result..)

Part of the "secret" is in the materials but a big component of the look is in the ligthing. You don't get "wet and shiny" without enough light to create the highlights. For example, IBL would be the wrong choice. A couple of mesh lights, scaled down a bit, would be better.

The cornea should be already set to Glass, which is the right material. Just make sure that you don't have a trans map for it. The sclera should have a failrly bright specular color. For example, 45,45,45. Glossiness for the sclera should be also pretty high, 8500-9500, depending on the lighting. The iris doesn't matter that much, the reflection should appear on the cornea.

Make sure that you are using eye textures that don't have "baked-in" highlights and then place a mesh light in front of the eyes of the subject, off camera. Make sure that the light is scaled down to 100% (it comes scaled to 200% by default). You might want to scale it down even more.

Also, remember that in real life, and in Lux, light reflect at an angle equal and opposite to the angle at whioch the light hits the surface. This means that the position of the camera and light will determin if you can see the reflections from your point of view. 

Hope this helps.
