=== Atmospheric Light Scattering === | |||
==== Volumetric Grass ==== | |||
Thanks to changes in the way random vegetation is managed when not visible, FG can now render volumetric grass on the terrain (for instance the airport keep) using the random vegetation system without blowing memory consumption. A grass texture matching color with the ALS airport keep effect is already available, but not activated by default since it doesn't look so good with other rendering frameworks. | |||

To explore this yourself, add the following lines to the Grass/Airport/AirportKeep/Greenspace landclass in Materials/regions/global-summer.xml: | |||
<wood-coverage>10.0</wood-coverage> | |||
<tree-texture>Trees/grass_blades.png</tree-texture> | |||
<tree-varieties>1</tree-varieties> | |||
<tree-range-m>200.0</tree-range-m> | |||
<tree-height-m>0.3</tree-height-m> | |||
<tree-width-m>1.0</tree-width-m> | |||
Just as trees do, grass changes with the season and gets little nests of frost when below the snowline. | |||
