Topics directly relevant to making outdoor areas. (For general mapping help, see Category:Level Design.)
- Skybox (2D) — basic skies
- 3D Skybox — adding items (such as buildings) to the skybox
- Displacements — terrain (such as hills, cliffs, caves, and non-flat grass)
- Precipitation issues — to make sure your rain/snow works right.
- light_environment - Both Direct and Diffuse light coming from the skybox ("toolsskybox" texture).
- env_sun - places a glow sprite in the skybox to represent the sun itself.
- shadow_control - necessary to control the dynamic shadows cast by light_environment.
- func_precipitation - brush-based entity for rain or snow.
- func_viscluster - for merging visleafs in large, open areas.
