Eye, eye do have an eye-ray question!

I noticed several very nice eye packages on sale right now for G2F (I'm not using G3F currently).
I would like to expand my eye variety. BUT, these all seem to be 3Delight based.
My question is, how difficult would it be to use them with Eye, I mean Iray? I assume they're mainly just maps, so could I like swap them into place? use them and hit them with Uber?

Which ones? I know I bought a set (don't remember which one off hand) that actually did have a custom 3DL shader, in addition to maps.
Hi, I believe you could swap out the eye maps, then apply the IRay G2F shader to your whole character, and all would be well. :-) I think the IRay shader is in G2F/Materials/IRay.
If all else fails you could just use the 3DL mats, Iray will render them, just 3DL wont render Iray materials. It will just take a bit longer for render times because it has to compile two different sets of Shaders know this because of some tests i was doing. This Vic 6 is using ALL 3dl mats and she rendered ok. But in general its easy to convert just choose the eye materials in the editor apply the uber base to all of them Cornea, iris, pupil etc....then use the Iray thin water shader on the cornea and the tear using CTRL double click and chose ignore maps. If by chance the Scelera renders black mess with the refraction index in the editor sometimes it converts at too high of a refraction making the scelera black.

Do not forget that a lot of older eye textures come with burnt-in eye relections, because getting real eye reflections was a lot harder using a biased renderer. With iRay eye reflections come naturally, so ideally you want eye textures with no burned-in reflections, which some of the older products may not have.
I'm looking at Forbidden Whisers stuff (big pc sale on them). Do/would G3F (or v4) eyes work for G2F? I know there were changes with Genesis so they don't work well with G2F
Biased/unbiased has nothing to do with how easy it is to get eye reflections...
The default REYES renderer in Studio for 3Delight with a Max Raytrace Depth of 2 is NOT the optimal setup to provide real eye reflections. A MRT HIGHER than 2 IS a requirement, 4 or more is much better.
Turning OFF 'Multiply Specular Through Opacity' is absolutely necessary.
The full raytracer, while not absolutely required will be better/quicker (enabling Progressive turns on the raytrace hider).
And for the eyes themselves, a Corneal Bulge morph is needed.
On the eyes, everything is the default Studio shader for 3Delight. G2M with just the default shader. There is a skydome and an environment light, with a spot set to Specular only.
Here's another render...this time the default REYES render...same lighting.
Now here's the kicker...remember I said the full raytracer would be faster?
Well the first render finished in 3 min 58 sec. (This was with Mustakettu's render scripts to enable the full raytracer).
The second 1 hr 14 min 15 sec.
Ok I stand corrected, however eye reflections are undoubtably easier (and probably quicker) in iRay compared to 3DL
Yeah...they are quicker...and since the defaults will just 'do' them, easier. If you turn on the caustic sampler, it will make them even better, but slow down the render a bit.
A slight different reflection/eye question, but related...
