This atmospheric shader node simulates the effect of light scattering, which causes more distant objects to appear lower in contrast, especially in outdoor environments.

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.

This value changes the rate of the exponential decay along the direction axis. 

The color of the fog. Unsaturated values work best.

Determines the starting point for the fog along the axis set by the direction. 

Determines the axis for the direction of fog.
