In VrayMaterial under the BRDF Tab, what does the slider Soften do? Or is supposed to do, because it seems to has no visual influence. It’s not included in the Vray help.
If softens the edges of hilights at grazing angles - see the attachments. In the first image, the soften parameter is 0.0, and in the second - 0.1.
Best regards, Vlado
