That’s awesome chohole! I’ve been having trouble actually getting the reflection to actually react to the light   Love the vibrant colour smile what sort of settings do you find work for you if you don’t mind me asking? I posted my parameters but I’m not happy with it yet.  I thought the topic might interest some ppl since I havnt came across it before raspberry

I am going to play with it a bit more. The subject got a couple of Brycers interested apart from me. Dave Savage did it this way, looks good.

For my settings I have used a lot of ambience and quite a bit of reflection.  The eye cornea Is a glass setting, 100% transparent quite a bit of reflection and specualrity and also altered the refraction percentage to water but with a tiny tad of colour fed into the glass transparency, which is something I am not certain you can do in DS or poser.

I have the eye map fed into diffuse channel at 100% and then Ambience turned up as well.  I had this particular figre already set up in bryce, so the puil is not made larger, but I played around until I got it to blend with the settings I had on the pupil.

Trouble is Bryce settings are a bit differnet, as all programs deal with textures, mats or shaders, whatever you want to call them, a bit differently.

I’m pretty sure you can do it with HSS or Ubersurface. I seem to recall there being (in addition to the usual opacity settings) a section for ‘transparency’ that takes colour.

Thanks so much chohole! I’ll check out the link and work on the parameters with what you’ve described to me as soon as I knock off from work.  I’m sure there’d be similarities between the softwares.  I will get there and finally be able to share with everyone how to do it lol. Also I’d love to see your progress on your eyes. smile 

@thinmick thanks heaps for the tip I’ll be looking into that smile I’m not sure from memory, but I may have set up the HSS on the character already. I’d have to look at the parameters again. My iPhones being real slow lol

Here’s a quick attempt by me.  Took all of about 5 minutes to set up, and about 30 seconds to render.

Left eye has eyeshine, right has none.  Both corneas are natural reflection.  1 Spotlight to the front right.

I created a retina from a plane primitive, inserted it into the eye, set the ambient, reflective, and specular colors.  Set the pupil to Opacity 0, applied a glass like setting to the cornea for reflection.

Wow that’s clever Kendall ! I can only see low res as I’m at work on my mobile but from what I can see it creates shadow and the light hits it quite nicely   That may mean it may not require the painted ambiance map I used earlier. How does both eyes go when there’s the angled light in your first render? Thanks for your help smile I so wish I was at my puta right now… So many great ideas to try smile

I’m in the process of rendering an avi of the spotlight traveling from one side to the other so that you can see the effect of the technique.

BTW my son says a good texture and then play with uber surface, which I think was a suggestion you already had.

Yeah, I was suggested a reflection map (Trialled first in this thread) And I was suggested an ambient map which I progressed towards, the ambient map that I posted of the Painted eyeshine on M5 eye texture was effective, likewise both proved artificial, but of course they definitely had their benefits! smile  I’m not sure what texture you refer to?

Additionally, I seem to have an issue with the reflection itself… It seems that even without light the reflective surface is illuminating ??? Odd. There is only one light with shadows on, completely aimed at the side of the head, definitely not hitting the furthest eye, no ambient map and ambient is off. This is doing my head in lol!

Unfortunately Neils is a bit tied up with other things at the mo (He is a mature student at Uni, and also a PA , with the PA sale coming up very soon) other wise I would challenge him to show you what he means.
