This page provides information about the Environment Fog Component in V-Ray for Grasshopper.


The Environment Fog component simulates particle media like fog or atmospheric dust. By default, it scatters the light emitted from all light sources.

Input Parameters

Color (Color) – Defines the color of the fog when it is illuminated by the light sources.

Emission (Color) Controls the fog emission (self-illumination). You can use this parameter to substitute ambient illumination inside the fog, instead of using GI.

Distance (Number) – Controls the fog density. Larger values make the fog more transparent, while smaller values make it more dense.

Height (Number) The fog starts at this level in the Z axis and continues downwards indefinitely.

Scatter GI (Boolean) – Enables the fog to scatter global illumination. Note that this can be quite slow.

Affected Type (Integer) Determines which scene lights affect the fog.

Lights (Generic Data) – List of Lights to affect the fog.


Output Parameters

Volumetric (Generic Data) – Environment volume shader output that can be connected to a V-Ray Environment component.
