Rollover image This atmospheric shader node simulates the effect of light scattering, which causes more distant objects to appear lower in contrast, especially in outdoor environments.
The Fog shader can be found under Arnold > Volume > Atmosphere in the Material Manager.
Once you have created the fog shader, drag it onto the Atmosphere attribute in the Environment - settings section of the Main Arnold Renderer settings.
Fog shader has the following attributes:
Color
The color of the fog. Unsaturated values work best.
Distance
Fog distance controls the fog density. Fog density is modeled with an exponential distribution. Smaller values make the fog appear less dense, while larger values make it appear denser.
Height
This value changes the rate of the exponential decay along the direction axis.
Ground Normal
Determines the axis for the direction of fog.
Ground Point
Determines the starting point for the fog along the axis set by the direction.
