CW Eye - A procedural eye material

by Christoph Werner in Models

Version 1.3 | Updated 2018-05-23

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

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.

Tutorial: how to bake a procedural material into textures


Is it possible to generate regular texture images from this material?

Yes, you can bake the procedural results into a texture page. To do this please use blenders internal texture baking system. I have prepared a small tutorial video on the Documentation page for beginners how to bake textures.

Following information can be baked into a texture:

  • Color information
  • Bumpmap information (Greyscale image)
  • Normalmap information (Tangent normalmap)
Do I need textures for using this material?

No. The whole material is procedural. No textures needed.
