There are 4 materials with the Mil figures Pupils - texture (I use slight transparency in Poser to give some depth) Iris - texture EyeWhite - texture (This name varies with the figure I think. Sclera would have been more precise and less ambiguous) EyeBall - 100% transparent - for light reflections only - (This name also varies I think. Cornea would have been better) a texture may affect the quality of the reflection? It is an outer layer over the main eye mesh. You have the sclera with either a black diffuse color or black texture. You have a reflection on the pupil - If you do not have the corena in use, then it is on the pupil texture. If you use the corena layer, you do not need (or really want) the highlights on the main texture.
