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.
aiFog can be found in the atmosphere menu under environment in the Render Settings window.
The aiFog node can also be selected from the outliner (Show Dag Objects Only must be disabled).
AiFog accessible through the Outliner
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.
