This package is a shader allowing you to easily setup eyes for your game.
Very easy to customize, many parameters will give you full control over the colors, the sizes, and the blend between each components of the eye (pupil, iris, sclera, and veins).
The package contains scripts to make pupils react to light and twitch in a life-like way, and have eyes look at point of interests.
A mesh with three LOD levels is already in the package, as well as some base textures to give you a quick start.
Here is a link to the demo for a preview of the eye customization :
