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

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