This page contains information about the V-Ray Fresnel Texture in V-Ray for Modo.
V-Ray Fresnel is a simple texture map blends two colors or maps based on the angle of view and an index of refraction. For example, you can connect the VRayFresnel texture to the specular color of a normal Modo material in order to create fresnel reflection.

Fresnel lor – Specifies the index of reflection to use when calculating the Fresnel term.
Refract Ior – Specifies the refraction index of refraction for the underlying surface. This is ignored if the surface has a volume shader.
Front Color – The color for the texture when viewed frontally.
Side Color – The color for the texture when viewed at a grazing angle.
