Path-Traced Fog

SettingDescription
Path Traced Fog Enables Path-Traced fog using volume absorption and scattering simulation with a Henyey-Greenstein phase function. The number of bounces is controlled by Max Fog Scattering Bounces
Density The density of the fog medium
Height The maximum height of the fog volume
Falloff Exponential fall-off of the fog
Color The color of the fog medium
Asymmetry (g) The asymmetry of the Henyey-Greenstein phase function ("g" parameter)
Use +Z Axis for Height If set the volume height is considered along the positive Z. Otherwise use the positive Y axis
