shadow_control

shadow_control is a point entity available in all Source games.

Class hierarchy
CShadowControl ↳CBaseEntity
shadowcontrol.cpp

It defines the direction, color and attenuation distance of all dynamic shadows created for the entire map.

Bug:At least in Counter-Strike: Source, if the current map does not have this entity, shadow properties (angles and distance) will transfer from previous map that had shadow_control. Confirm in other games.
In at least Day of Defeat: Source, if the current map and no previous maps have contained this entity, shadow color will be inherited from light_environment's _ambient KV.   [todo tested in ?]

Important:This is a preserved entity in .

• On a new round entities with this classname will intentionally not reset. You can use logic_auto to emulate resetting it.
• Killing it removes it forever, as it is not respawned on a new round.
• It cannot be spawned with a point_template.
• Parenting this with non preserved entities may have undesirable effects.

Note:The properties of this entity apply to the whole map. Multiple instances of this entity within a map may cause errors.

Note:

• Since Left 4 Dead, shadow direction can be determined by local lights instead of a global value. See below for more details.
• Deprecated in Counter-Strike: Global Offensive. Use env_cascade_light instead
• In Black Mesa shadows are disabled by default. Also shadows always use lowest shadows detail setting, so that they look like a darkening under models, due to this they do not stand out against background of dynamic light sources.

Keyvalues

Name (targetname) <string>

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

Pitch Yaw Roll (Y Z X) (angles) <angle>

This is the shadow direction. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, and roll is the rotation around the X axis.

Tip:Pitch is the sun's angle of elevation from the ground, and yaw is its compass bearing.

Shadow Color (color) <color255>

This is the color of the shadows.

Maximum Distance (distance) <float>

This is the maximum distance the shadow is allowed to cast, in inches.

Tip:Shortening this distance can be used to approximate the effects of diffuse lighting.

All Shadows Disabled (disableallshadows) <choices>

Disable shadows entirely.

Enable Local Light Shadows (enableshadowsfromlocallights) <boolean> (in all games since ) (also in )

Enable shadow direction to be calculated on a per-entity basis and to be dictated by the light closest to the entity.

Note:This keyvalue may not be available in some FGDs.

Code:There is a custom version of this feature which could run on previous versions of Source. Click here for more information.

Force Blob shadows (ForceBlobShadows) <choices> (only in )

Enable blobby shadows (same that you can see if use lowest shadow detail).

Warning:Never set to 0, otherwise game will crash on map launch.

Inputs

color <color255>

Set the shadow color.

direction <vector>

Set the shadow direction.

SetDistance <float>

SetShadowsFromLocalLightsEnabled <integer> (in all games since ) (also in )

Set local light shadows enabled state.

Note:This input may not be available in some FGDs.

SetForceBlobsEnabled <integer> (only in )

Set shadows blob state.

Warning:Never set 0, otherwise game will crash with this message.
