Complex IOR Material for Blender

This product comes with a .blend file that contains the shader designed to provide the ability to easily and efficiently create renders that are based on the physical parameters of the complex index of refraction. The scene is as shown in the cover photo.

The material uses the complex index of refraction evaluated at 400nm for blue, 525nm for green and 650nm for red and supports both conductors and dielectrics. Furthermore, the material also supports varying roughness and reflection anisotropy per colour channel, and correctly computes the medium absorption of absorptive dielectrics.
