MacroFacetNormal

A pseudo randomized normal, which generates flat facet normals using the GGX distribution.

Scale

The scaling factor of the facets size.

Scale3

The scaling factor of the facets size for each component.

Jitter

Controls the spatial distribution of the facets.

Roughness

Controls the amplitude of the facet normals distribution.

Mode

The source coordinates for the noise. 'Object' sticks the noise to the object, 'World' sticks to the world coordinates, 'st' uses texture coordinates and 'Input' allows connecting a custom coordinate set.
