Fresnel PBR Node


Description

This node calculates a physically-based approximation of Fresnel falloff in accordance with the Roughness and Specular values and the viewing angle at which the surface is viewed. The output value can be used as the intensity for Fresnel reflections, transparency, and other effects.
