Version 1.3 | Updated 2018-05-23

CW Eye is a real procedural material shader tree for Blender. Developed for the Cycles Renderer.

What means "real" procedural?

  • No special eye mesh needed. Add a simple sphere (or whatever) and drag and drop the material. That's it!
  • No UVs needed. CW Eye just works.

The most eye materials comes with individual mesh models and shape keys to simulate the eye anatomics. CW Eye goes a different way and does all this procedural.

Save a lot of time and create countless eye variations just by changing some values in the shader. Starting at "simple" human eyes you can create eyes for aliens, zombies or whatever you imagine.

This package already includes five cool eye presets I've prepared for you. Feel free to use them as a starting point for your own variations!

Your results can be baked optionally into textures by using Blenders internal bake system. If you are not familiar with Blenders texture baking system, visit my free tutorial link in the documentation tab.
