Global Fog

The Global Fog image effect creates camera-based exponential fog. All calculations are done in world space which makes it possible to have height-based fog modes that can be used for sophisticated effects (see example).

As with the other image effects, you must have the Standard Assets Effects package installed before it becomes available.

Properties

Property: Function:
Fog Mode The available types of fog, based on distance, height or both
Start Distance The distance at which the fog starts fading in, in world space units.
Global Density The degree to which the Fog Color accumulates with distance.
Height Scale The degree to which the fog density reduces with height (when height-based fog is enabled).
Height The world space Y coordinate where fog starts to fade in.
Global Fog Color The color of the fog.

Hardware Support

This effect requires a graphics card that supports Depth Textures. See the Graphics Hardware Capabilities and Emulation page for further details and a list of compliant hardware.
