An example of a well-lit room. It is lit by a combination of the following:
* The lamp above consists of a [[prop_static]] shade, providing 100% linear light with a [[light_spot]], while dazzling the player with an [[env_sprite]].
* The window filters in a [[light_environment]] together with a [[shadow_control]] and an [[env_sun]]. However, the window opening itself simulates refracted sunlight through an invisible ''white001_nochop'' material brush.
* To the left is a "developer only" button which automatically builds [[cubemaps]] when pressed (through a [[point_clientcommand]] issuing the ''buildcubemaps'' console command).

Probably the only thing missing in this picture is HDR lighting.
