Eye - Lighting Challenge

Woah congratulations on the top row!Now the nose reflection had been mentioned I realise why it looks that way.My only thoughts on solving the issue would be in postwork as you can hide the nose from reflections or lower the opacity of the reflective material?Anyroad,just wanted to say well done and sorry for the rushed spelling errors on my other post here.

VERY nice eye!!

I just went thru some hell trying to get eyes to render well so this really strikes a chord in me.

Really fantastic!

Taron wrote a feature for messiah that actually renders out an eye procedurally as was Gollum’s eyes in LOTR.

calum5ZB - Thx’s, I already have a fresnel ramp on the eye for the reflection and with that it still shows up. I figure next go around on the eyes would to just to combine the fresnel ramp with a painted texture of some to control the reflection better.

Scott - :smiley: Thx’s man, I really dig your work! Yea rendering eyes and skin for that matter are very challenging to do.

crossbones - for this eye I actually combined a technique where its procedurally done with textures and then I bake that out and combine it with some photo reference and do some painting to tweak it.

I found this photo which is interesting because it clearly shows how the bulging cornea reflects like an inset sphere. The reflection of the nose can be clearly seen.

That eye is a perfect example, The eye is so complex from its subsurface scattering to the odd manner of refraction / reflection inside. I’ve just come to the conclusion from now on that anything outside of the bulging cornea reflects very minmal to none.

Nice Work Miguel!!!

Fantastic stuff! My only nit-pick is that the shadows look a little too harsh to me. I think that a person reflected in the eye would not go amiss either.
If you think about it, you can’t look into another’s eyes without seeing yourself.

Whoaaaa - deep.

:smiley: thx’s scott!!

WoodyLWG that is a true adding a person with a cam would have been a nice little detail to add. Yea the shadows from the lash’s are a bit harsh since I was forced to use depth map and not raytraced.

Sweet!!!

My only crit would be that for me anyways the eyeballs positions seems contrary to the way the nose and the rest of the face seem to be facing. but this is a close up and I really don’t know what the situation the person is in and what is drawing their attention. It just seems off I guess…to me…probably not to any of the sane folks out there.

hahaha
:wink:

cool!!

aminuts - :smiley: I usually just look at it like this Iam sane and everyone else isn’t LOL. But as for position Iam not quit sure what you mean, are you talking about the fov of the camera or about the model position itself.

Just awsome work mate, it really looks like an eye. The veins are perfect. :smiley:

freewaldo - Thx’s, here is the link to the contest http://forums.cgsociety.org/showthread.php?f=185&t=411452

Hey there. Beautiful eye man. I agree with you about tha conclusion that the outer eye does not reflect very much at all.

I have a one Q’s and one crit…and I only crit becuase I know you want feedback :slight_smile:

I think the Cornea would buldge a little more than you have it right now. It seems a liitle flat.

Did you use a bump on the iris or simply a good reference image?

Congrats on top row. Well deserved. We are all commenting on your eye and forgetting that your skin is just beautiful…:+1:small_orange_diamond:+1:small_orange_diamond:+1:small_orange_diamond:+1:small_orange_diamond:+1:

Hi Elixir, Thx’s for the kind comments! I thought as well the cornea would bulge some but when I had it bulging it simply didn’t look right, from the reference images I looked at the eye ball always looked pretty smooth straight on only from different angles can you tell that the cornea is bulging or at least that is what I came to see. Yea I did use some bump on the iris since when you get that close to the iris you start to see the fibers in the eye.

I would love to see some wires :slight_smile:

Elixir here is the shade view of the mesh I ended up using, the wire is way to dense to just show the wire since I used the imported mesh from zbrush that I tweaked.

Here is one mesh I start to experiment with to bring out the skin features but in the end I just used the bump map to bring those fine details.

Thanks mate, your about the best one in the contest.

good work :smiley:
