light_environment is a point entity available in all 
GoldSrc games.
Description
Creates the sunlight emitted from sky brushes. There needs to be one per PVS if using the default compile tools. Only one is needed per map if using the ZHLT compile tools.
Key values
- Name (targetname) <string>
- The targetname that other entities refer to this entity by.
Important:Naming a static light radically changes its behavior. See Naming Lights for details.
- Pitch Yaw Roll (Y Z X) (angles) <QAngle>
- This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.
- Pitch (pitch) <angle>
- Overrides the pitch value in Angles, even if omitted, so it needs to be specified. Contrary to Angles, the rotation of this pitch is measured counter-clockwise from the horizontal, so that 90 is straight up, while -90 is straight down. (It's simply the negative of a normal pitch value.)
Light:
- Color + Brightness (_light) <color255 + int>
- The RGB color and brightness of the light. Colors must be between 0 and 255; brightness can be anything.
Note:Negative brightness will suck out the amount of lighting that the equivalent positive brightness would cast.
- Appearance (lightstyle) (style) <choices>
- Various lightstyle presets. Cannot be used on named lights.
Lightstyle presets (epilepsy warning) Expand
- Custom Appearance (pattern) <string>
- A string of english letters, like a sequence of piano keys, that define a pattern of brightness. a is 0%, m is 100%, and z is 200%. Updates at 10 Hz. Requires light to have a targetname.
ZHLT light source:
- 0 : Default
- 1 : Inverse Linear
- 2 : Inverse Square
- Texlight (VHLT+) (_tex) <texture>
- HLCSG will rename this entity to light_surface, using the specified texture as the emissive texture. See light_surface page for additional relevant KVs.
- Ambient (ZHLT+) (_diffuse_light) <color255 + int>
- Sun spread angle (_spread) <integer>
- Model lighting only (VHLT v16+) (_fake) <boolean>
- Treat this entity as an info_sunlight, causing it to not affect lightmaps.
