Enabled – – Turns on/off the aerial perspective effect.
Affect Environment – When disabled, the atmospheric effect is applied only to camera rays that hit actual objects, but not to rays that hit the sky. This is because the VRaySky texture already takes into account the amount of scattered sunlight. However, it is possible to enable this option for artistic effects, especially with low visibility ranges.
Atmospheric Height – Specifies the height of the atmosphere layer. The value corresponds to the units set in the current Revit project. Lower values can be used for artistic effects.
View Distance – Specifies the distance at which the fog has absorbed 90% of the light coming from objects behind it. Lower values make the fog appear more dense, while larger values reduce the effect of the aerial perspective. The value corresponds to the units set in the current Revit project.
Inscatter Multiplier – Controls the amount of sunlight scattered from the atmospheric effect. The default value of 1.0 is physically accurate; lower or higher values could be used for artistic purposes.

Enabled – – Enables or disables the Environment Fog.
Color – Defines the color of the fog when it is illuminated by light sources.
Emission Color – Controls the fog emission (self-illumination). You can use this parameter to substitute the ambient illumination inside the fog, instead of using GI.
Emission Multiplier – A multiplier for the Emission parameter.
Fog Height – The fog is assumed to start from a certain Z-level height and continue downward indefinitely. This parameter determines the starting point along the Z-axis.
Particle Distance – Controls the fog density. Larger values make the fog more transparent, while smaller values make it more dense.
Use Artificial Lights – When enabled, all artificial lights in the project will have an effect when rendering the environment fog.
Affect Background – Enables or disables the tracing of background rays.
Affect Secondary Rays – Enables or disables the tracing of secondary rays through the volumetric.

Places an infinite plane at the specified height.
Height – Specifies the height of the Ground Plane.
Material Material – Specifies a material for the Ground Plane. Note that selecting a V-Ray material from the drop-down list enables the Infinite Ground Plane. Respectively, removing the selected material disables the Infinite Ground Plane.

Note that the global material overrides do not affect the Infinite Ground Plane. If that is needed, the material should be changed manually.
