Left or right-click on any color slot opens additional color selection options.
Emission Color 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 – 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.

The Infinite Ground Plane scales the material assigned to it by a factor of 100. The material scale can be adjusted from within the V-Ray Asset Editor. In all cases where that material is assigned to other geometries, it is recommended to use a duplicate copy of it.
