Anisotropic

BEAM uses the famous Henyey-Greenstein phase function (HG) to compute the scattering direction of incoming light. Anisotropic value plays a big role in this part, where low values make light scatter more forward (seen by looking directly at the light source) and high values make light scatter in all directions (seen from the opposite direction of the light source, think of a top down RPG camera).

Anisotropic = 0.3 Volumetric Lighting Anisotropic

Anisotropic = 0.7 Volumetric Lighting Anisotropic

Anisotropic = 1.0 Volumetric Lighting Anisotropic
