Fresnel Shader

The Fresnel shader contains only Fresnel controls for the specularity.

Roughness field
  Displays the shape of specularity of the shader.
Fresnel Offset field
  Displays the total amount of specular light.
Fresnel Factor field
  Displays the amount of specular light at grazing angles.

TipTo cancel out the Fresnel effect altogether, set the Fresnel Offset to 0 and the Fresnel Factor to 100.
