Cook-Torrance Shader
 
 
 

Use the Cook-Torrance shader for high specularity materials, such as metals or shiny plastics. This shader includes Fresnel controls for 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.
