i took down 95% of my gallery long ago, and didn't put back up
remaining ones were for "special" cases, friends asked me to keep em
the detail in them is far from perfect lol but they weren't made for that

the iris in a human eye isnt accually flat, its very slightly concave, but either way
any decent eye models i've seen, have morphs to allow both ways
i like a very very slight spec on the iris, but thats just me :)

next the eyewhite, i find by having 2 layers in the mesh, very very slightly apart
tends to work a bit better, texture on the inner layer, with the outer used to create
a slight "milky fog" effect, that appears to be between the 2 layers, and includes veins

then comes the pupil, i find having an "inside" to the eye works strangely, just a 3rd
sphere shape inside, with a hole where light passes through the iris center
setting the color for the inside of the eye to about 15R/15G/15B, and a bit of work
with diffuse node to cut out too much light (so no bright sun makes pupil look white)

cornea has reflection, but needs thebright objects to reflect stronger than the dim ones
i found multiplying the reflection times itself works decently, but i've seen better

the "tear gathering" at the lower edge of the eye, can be done by a careful setup with
AO node, N node, and some math, plugged into displacement chan

i spent 3 months trying to create realistic eyes in P6, i can go on forever :P
having a girlfriend with pretty green eyes for a live reference was very useful :)

runs back over to carrara to play with better lighting :D
