Anisotropic Shader
 
 
 

Use the anisotropic shader to control the specular effect of the highlights.

X Roughness field
Displays the shape of specularity of the shader along the X axis.
Y Roughness field
Displays the shape of specularity of the shader along the Y axis.
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.
