Interface

Anisotropy

The U-direction roughness in relation to the V-direction roughness. Click the button next to Anisotropy to select a map, scene material or sample.

Rotation

The anisotropy angle. The range 0 to 1 maps one full revolution. Click the button next to Anisotropy to select a map, scene material or sample.

Auto

Automatically orients the anisotropy.

Map channel

Orients the anisotropy based on a given texture space.
