The new anisotropic BRDF (beta) is available to use and it is an input in the Base Material node. With the tooltip saying the following:

"Controls how anisotropic the Material roughness is. Anisotropy of 0 is isotropic. Anisotropy of 1/-1 is Maximally anisotropic along the tangent/bi-tangent respectively."

What would be the best way to use this new input? Like would Metal be 1, What would be -1? What about if I want to simulate radial anisotropy or a brushed feeling, would input a grayscale map with the anisotropy lines and how will this look like or the values on the map? What would be 0 or as it has been debated wood can have some anisotropy what can this value be?

I am looking forward to using this value but I am a bit confused about the way that I should be using or working with these new parameters. I would appreciate a lot that any can clear my confusion.

Thanks,
