Environment Fog

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

Overview

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.
