light_directional is an internal point entity available in all Source games since 
Left 4 Dead. It is a directional light with no falloff, similar to light_environment.
Bug: Non-functional in Alien Swarm.Keyvalues
- Pitch
<integer> - The downward pitch of the light from the sun. 0 is horizontal, -90 is straight down.
- Brightness
<color255> - The RGB color and brightness of the light. Colors must be between 0 and 255; brightness can be anything.
- BrightnessHDR
<color255> - Brightness override used in HDR mode. Default is
-1 -1 -1 1, which means no change.
Warning: The fourth digit must be positive. Otherwise all light will be sucked out of your map! - BrightnessScaleHDR
<float> - Amount to scale the light by when compiling for HDR.
- SpreadAngle
<float> - The angular extent of the light for casting soft shadows. Higher numbers are more diffuse. 5 is a good starting value.
Angles:
- Pitch Yaw Roll (Y Z X)
<angle> - 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.
