Doing up a render with V4 and the eyes get all glassy and bleached when I render. Any idea on what's causing that?

Can you post a larger image?  Hard to see that one.

It looks like the specular from the light has landed right on the pupil. If you move the light or the figure the eye will improve.

I only see one specular dot. A rounded eye should show two specular dots under normal circumstances.

It may also be that you have a texture applied that has a fake reflection on the eyes you might check in the material room.

yeah, I've seen textures change on eyes, depending on what you use...

Looks to be the fault of the lighhts. Moving the light helps. Not sure how to add specular dots though.

If you are otherwise happy with the light position and settings, I would suggest you reduce the specular reflection strength on the appropriate eye materials.

By way of example, this is standard V4. The specular reflections on the Cornea, Tear and Lacrimal are generated by Anisotropic nodes in their shaders. Her right eye (on the left as we look at her) is "as loaded", and her left eye is with the Anisotropic node Specular_Value reduced to one half of its original value in the three shaders.

You can also adjust the size of the specular reflections by changing the u and v Highlight Size on the Anisotropic nodes.
