Env projectedtexture

Casting shadows.

Creates a dynamic shadow-casting light that affects all objects in the world. Used for the Episode Two flashlight.

Bug:Does not accept a configurable texture value from Hammer - will always default to the flashlight. You must use the SpotlightTexture input instead.  [todo tested in ?]

Enabling multiple shadow maps

Valve's games only allow one projected texture to cast shadows at a time - including the player's flashlight! To surmount this, shadow casting can be disabled on each entity with the enableshadows KV, or for a proper solution a programmer can perform this C++ fix:

CClientShadowMgr::Init()
	- bool bTools = CommandLine()->CheckParm( "-tools" ) != NULL;
	- m_nMaxDepthTextureShadows = bTools ? 4 : 1;	// Just one shadow depth texture in games, more in tools

	+ m_nMaxDepthTextureShadows = YOUR_CHOSEN_MAX;

Garry's Mod has already had this done. Thanks to Garry for sharing the code!

Keyvalues

Projecting a texture.

• Template:Kv targetname

target

<target_destination> The entity will rotate to point at its target, no matter where it is in the world. See also lightonlytarget.

Bug:Can get glitchy.  [todo tested in ?]

lightfov <float>

The angle at which the texture is projected. The projection is square, but the texture can make it appear of any shape.

enableshadows <boolean>

Should I cast shadows?

lightonlytarget <boolean>

Should I light only the entity that is my target?

Bug:Non-functional.  [todo tested in ?]

lightworld <boolean>

Should I light world brushes?

cameraspace <boolean>

Display relative to player's view. Breaks things horribly unless the entity moves with the player.
