Eye Generator

Eye Generator builds photoreal eyes inside Blender: human eyes in every iris color, animal eyes with their real pupil shapes, and fantasy eyes that glow. Pick one of 40 eyes from the picture gallery, then change anything. The eyes rebuild live, track a look target and come with animatable pupils and blinks.

Every eye is built like a real one, the way film eyes are made: a sclera with soft color, mottling and branching veins, a concave iris whose stroma, collarette and pupil margin are real geometry, a separate refractive cornea with its bulge (IOR 1.376) floating on a real gap so nothing ever z-fights, and a crystalline lens behind the pupil. Cycles refracts through the cornea and can use MNEE caustics; EEVEE gets its own transparent cornea setup.

Irises are painted procedurally into high-resolution textures: radial fibers, crypts of Fuchs, contraction furrows, the collarette and pupillary ruff, limbal rings, freckles, speckles, reptile vein nets and metallic flecks, with complete, sectoral and central heterochromia. Export the textures as PNG for game engines.
