Blender addons Blender – Universal Human Eye Shader

Customisable eyeball materials for Cycles (textures available separately), for use with the included base mesh or with the Universal Human rigs/meshes. The shader is separate from the textures so as to provide a more affordable option for those wanting to supply their own textures. Instructions for making compatible textures that make use of all the parameters can be found here).
