This page provides information on the V-Ray Fresnel Map.
Overview
VRayFresnel is a simple texture map that blends two colors or maps based on the angle of view and an index of refraction. For example, the user can connect the VRayFresnel texture to the specular color of a normal Maya material in order to create fresnel reflection.
To illustrate the texture's effect, the example on right shows VRayFresnel applied to the diffuse channel of a VrayMtl. The Front Color is set to Black, the Side Color is set to a bright cyan, and the IOR is set to 2.0

Parameters
Front Color – Specifies the color for the texture when viewed frontally.
Side Color – Specifies the color for the texture when viewed at a grazing angle.
IOR – Specifies the index of refraction to use when calculating the Fresnel term.
