Settings

Step size

Adjust the size of probing inside a volume. Be aware about high performance effect

Long	Short

g (phase function)

Define direction of distribution of light inside volume. Default function is Henyey-Greenstein

• $\theta$ — the angle between the incoming and outgoing light directions
• $g$ — the asymmetry parameter ($-1 \leq g \leq 1$)

-0.2	0	0.6

Scattering

Controls how much light is scattered inside the volume. Higher values make the volume look softer and more glowing.

Low	High

Absorption

Determines how much light is absorbed as it passes through the volume. Higher values make the volume look denser and darker.
