They look fine if the iris texture is used as in poser but then you can't dilate the pupil. Should I just make a cornea material? Has anyone got a good one they want to share. I don't actually know how to create a material in carrara anyway. Love esther

I don't think you are going to be able to make a pupil dilate. I suppose you could make a shape you could constrict. Making a texture with different pupil sizes would probably be better.Easiest might be altering the pupil of an already existing texture or creating a texture that would go over that part of the eye to look like a smaller pupil.

Oops I didn't explain that properly. The cornea is that clear transparent layer over the front of the coloured (iris) part of the eye, so as long as it's transparent the iris and dilating pupil will show through just fine. It's just a matter of making the cornea look real ie sort of wet and glassy looking. I dunno quite how to explain it but if you look at someones eye from the side you will see. Poser people handle itin poser by either making the cornea same colour as iris, or making it completely transparent. If you make it completely transparent you loose the rounded look of the cornea. However in carrara there is the possibility of having a real looking cornea. Love esther

What I do for the corneas if I've imported it as a pz3 files is just put the alpha on the corena so it's transparent but leaves the highlight on it to make for a more realistic cornea. I can post a screen shot of my shader settings for the cornea if you'd like

I'm not a poser person, really, but here's a thought that you might be able to work with. One of the distinctive things about the lens of the eye is its refractive property. Perhaps your cornea should be mostly transparent (98% or more) and should have some refractive index added, as well. I'm not sure how the DAZ eyes are built, so I don't know how this would be implemented, but it should add to the realism of the eye, I think.... - Dex

I gotcha. I haven't done too much w/ poser stuff either or studied eyes, however, throwing this together I got what looks like a good place to start anyway.Heres a post. Uses V3 textures.

I didn't really set reflection this could be looked at. I didn't use alpha. 100% trans instead. Index of refraction is water. Shininess is 65%.

If you set to around 20% more or less that works. Don't want it to look like glass.

Reflection works a bit differently now. You set the shader part to a percentage(around 20%. You could try fresnel, but I don't think it will work well I would leave it a 0)

shiny I have high. 65% Under reflection the is another brach in the tree called shader click on that drop down then select value 1-100%. 16% looks ok. You may find viewing angle etc may change the look.trans is 100%, but no alpha.

ren_mem ( ) posted Thu, 26 January 2006 at 8:42 PM

yeah refraction is right. I am a bit confused because it looks like you have all the shaders for you model in there. The parametric map looks like it could be the cornea from the little ball, but you only want to do this to the cornea shader.I brought mine in via daz obj for this and merged groups so mine could be setup differently.If you look I just have multichannel then texture map.Set that shader under reflection to 16% value.

Your textures are different. Ignore the parametric comment. It doesn't matter.I am going out for a bit will be back so don't think I disappeared. I think you will have to tweak. Yours just looks a bit glassy so maybe just turn the shader under reflection down.

ren_mem ( ) posted Thu, 26 January 2006 at 10:53 PM

esther, I think part of the issue is your base texture looks like it may already have a reflection built in.I have seen some with fake reflections also. You may need to examine the underlying textures. Are the eyes just too glassy or what do they look like? I am sure not only do you need good textures, but there is probably tons of technique and theory behind doing eyes. Gotta be some tutorials around.

ren_mem ( ) posted Fri, 27 January 2006 at 1:14 AM

Yep. That will make a difference. Something made into the texture can throw things off alot.If you can't replace the fake reflection(which cannot be adjusted and won't look real)then you may need to turn reflection down.It will be hard to tell if this is your problem or something else.You could also try to use only reflection instead of refraction(or try refraction in a 1-100%)Shininess you may want to adjust also. You may turn shininess and refraction down to nothing then add them back that will help you see how each affects the texture.

ren_mem ( ) posted Fri, 27 January 2006 at 1:24 AM

Also, your really strong light in the eyes will effect it also(that may be for demonstration only). Try the fake GI Indoor lighting scene and see if you like that as a starting point.

in the shader with the texture I ticked the little box that said make white invisible. I don't know why I did this, or what it does but the cornea I think is looking better. I'm just going to check it from all angles. Love esther

i just took the texture away and changed it to a black colour - first test not too bad, but no reflections so i'm turning them back up and i think i'll have to turn some on for the pupil too. love esther

There is a reasonably priced set of eye textures in the market place that I picked up... great real looking irises and you can chose to use textures without reflections on them. I bought them and they work great for using them in carrara. I'm not trying to do a commercial for someone's product but if you want to know which ones let me know. And I made the mistake of a blonde... when I typed in alpha in my earlier post... I use transparency and a low refraction setting on the cornea. Great progress both of you! Christina

Hi Christina, Thanks, that sounds interesting too. do you use a texture in the colour part of the cornea and if so, with or without reflections usually? Love esther

ren_mem ( ) posted Fri, 27 January 2006 at 7:38 PM

Well glad it's working esther. The box you checked for transparency is normally checked when you are using the transparency channel like an alpha channel. This depends on how the texture is setup, but is often used. I think christina may be referring to what I mentioned earlier about setting the shader under refraction to a 1-100% value like you did with reflection and starting low and working your way up.You have to show us your render.enigmaticfrog I think posting the link is fine to a product you like...it is certainly relative.

enigmaticredfrog ( ) posted Fri, 27 January 2006 at 7:47 PM

I usually don't use a texture on the cornea... since our corneas are clear... and I use anywhere from 1.0 to 2.0 refraction. The iris textures I like are eye to eye by billy-t I think. I know the package is eye to eye here in the MP. Will pop out a render.... C~
