This atmospheric shader node simulates the effect of light scattering, which causes more distant objects to appear lower in contrast, especially in outdoor environments.
See the Environment page for more information on creating and attaching Fog nodes.
The color of the fog. Unsaturated values work best.
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 more dense.
This value changes the rate of the exponential decay along the direction axis.
Determines the starting point for the fog along the axis set by the direction.
Determines the axis for the direction of fog.
