This is what I do.
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

Thank you Zay for this very informative post!

Thanks Zay! That will be a HUGE help!

wow, this was beautiful!!!

Would You mind to share skin shader?

Regarding the eye lashes. I have tried this,the upsizing doesn't really help. If you change the gamma on the opacity floatimage that helps.

I have upsized another model, which somehow doesn't look that good overall.

Attached is one I am kinda happy with. I am trying hair in another picture.

Here is a 10 times upsized model in XSI. I still had to do the gamma on opacity trick.

The hair, I just slapped some hair on it, I am still learning

Call me a noob or what ever but I'm still lost when working with the eye's.

Here are the questions I still have that someone may be able to answer, and I have scowered the manual for versions 2.2 and 2.3 trying to figure this out.

Cornea: 100% transparent. ----- got it, that what was easy.
Tear: 100% transparent -------- go it, that too.
Eyesurface: exactly as recommended
Eyesocket: Leave it alone ------ yup that too.
Eyelashes: Got that figured out and works great.

Iris & sclera: Adjust the texture light (float) until it looks real - I don't see a texture light slider, also as stated I've left the surface tab as difuse, but at the same time I've tried pretty much tried everything when it come to sliding the slider and/or changeing things from floatimage to floattexture to image settings, even tried glossy and specular instead of diffuse. And of course tried six different eye types.

Lacrimal: Give it some shine to it but not too much. --- again I've slid ever slider from one side to the next and nothing, all I managed to get is an eye that looks jaundice in any type of light.

I've included a screen capture if that might help.

I love this program, love the images it can create, and would really hate to give up on it. As for the programmes I use. DAZ Studio with all settings to export as stated in both 2.2 and the 2.3 manual. Octane import setting are untouched.

And as this programme is still in beta? DAMN! Is it stable!

Use pathtracing and not directlighting! And then set rayepsilon to 0.0000 so you don't get a black shadow in the eyeball.
To lighten the texture use the gamma control.

BINGO! THAT DID IT!

Hell yeah I'm yelling that did it!!!

Not sure what this "black shadow" is that your referring to Ive not had to touch the rayepsilon.
