Anime Eye Shader

Made for a retro 3D platformer project; we wanted the characters to be able to look around and focus on objects in the world.  Using a sphere as an eyeball wouldn't work with the face geometry.

So instead, I created a  shader that allowed us to specify :

• Iris color  gradient (top and bottom)
• Pupil size
• Iris size
• Highlight size and  position
• Values to move  the eye left/right/up/down for looking

There are no textures! It's all created  with math to be more flexible and reusable.
