Copy full snippet

Remarks

How many octave to use for the multiple-scattering approximation. This makes the shader more expensive so you should only use 0 or 1 for better performance, and tweak multiple scattering parameters accordingly. 0 means single scattering only. The maximum value is 2 (expenssive).
