Spectral Shader

Basic Shader

Spectral Shader

The Spectral shader is ideal for prismatic or iridescent effects such as shiny pearls or the shiny colors on a CD. The calculation of this effect takes the camera perspective and the angle between the light source and surface into account. In general, the Spectral shader should be primarily used in a Specular layer (under Layer: Color) in the Reflectance channel.

Tip:
Note also the Thinfilm Shader, which will render these types of physical effects correctly.
