X Roughness fieldDisplays the shape of specularity of the shader along the X axis.

Y Roughness fieldDisplays the shape of specularity of the shader along the Y axis.

Fresnel Offset fieldDisplays the total amount of specular light.

Fresnel Factor fieldDisplays 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.
