Cornea: 100% transparent. Or low transparency and give it some shine.
Iris/sclera: Adjust the texture light (float) until it looks real
Tear: 100% transparent or for close up turn it to glass or set the transparency very low and give it some shine.
Lacrimal: Give it some shine to it but not too much.
Eyesocket: Leave it alone as you can't see it.
Eyelashes: Turn color to black or brown. Add the tranparency map to the opacity settings. Set power to 1.0. Adjust eyelash thickness with the gamma setting (lower settings gives a more thicker look).
Eyesurfaces: Opacity set to 0.05 to 0.1. Set diffuse color to black, specular sets the white relction in the eye, and set roughness to zero or close to it to give it reflection. Its best to only have the eyesurfaces use glossy and the rest to diffuse as this will give the best results.
To remove the black spots that can show behinde the eye, set rayepsilon to zero. This will also remove most shadow atifacts in the scene, but can freeze up Octane. This should be fixed in the new release.
I have asked Radiance a loooong time back to add the scale option for Poser when importing the OBJ file, so I hope it's in this new release. Otherwise he needs to get spanked as this was asked for back in April 2010
