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).
|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.|
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.
