This is high detailed 3d human eye. The model was done in Maya, texture in Mari and final render image in Houdini Arnold. I'll be using this eye for my personal 3d characters. I followed photo realistic references for eye details. In eyeball has a 5 layer's Sclera, Fluid, Iris, Lens and Pupil. I used XYZ displacement for detailing and on top of create bump map in nuke. The Eye has SSS, Transmission and used Dielectric priority for each geo and more realistic reflections.
