Note:在Gmod中，可以同时有9个启用的
Note:
将此上限提高到了8
Note:在
里，你可以同时使用4个投射纹理。 这个上限可以通过启动参数
传送门2大量使用投射纹理作为地图光照
env_projectedtexture是一个存在于所有的 Source 游戏自从 Template:Name=Half-Life 2: Episode One 以来的点实体。它投射一个纹理作为一个动态光源，可以影响地图内所有的物体。还可以选择使用阴影贴图。 投射纹理不像其他光照实体的光照一样是预先生成的，这种光是在游戏内实时计算的，地图本身不需要经过VRAD处理就可以使用。
Todo: This template is currently using deprecated suf or {{Lang}}-based translations. Please use the main {{Code class}} instead, which uses {{Autolang}}.
在源代码中，它由 class CEnvProjectedTexture 代表，定义于 env_projectedtexture.cpp。
注意事项与Bug修复
- V社的游戏仅支持在同一时间内在PVS里渲染一个阴影贴图
- Template:Note:zh-cn
Warning:在
中，无论阴影质量设置如何，都只能在地图内使用一个投射纹理- Fix:可以遵循该教程修改/删除此限制。
Note:在Gmod中，可以同时有9个启用的env_projectedtextures。你还可以在启动参数中添加-numshadowtextures #以提高上限。 # 是游戏应允许的阴影贴图数量。Note:将此上限提高到了8Note:在里，你可以同时使用4个投射纹理。 这个上限可以通过启动参数-numshadowtextures #或者gameinfo.txt中的CommandLine部分来增加。- 仅当玩家的阴影质量设置为“高”时才能显示投射纹理。如果您的阴影质量设置里不显示这一选项，你可以在游戏的启动参数里添加
-force_vendor_id 0x10DE -force_device_id 0x1180<、code>来强制显示 - Note:在里，
env_projectedtexture产生的阴影在阴影质量设置为“低”时显示 - 在多人游戏里，
mat_supportflashlight必须被设置为1才能让手电筒正常工作，在TF2中，这个指令默认被禁用，故没有特殊修改的话，该实体无法在TF2中使用 - 手臂模型不会接收来自投射纹理的任何光照和阴影，除了Gmod和传送门2您可以按照该教程修复这个Bug。
Bug:在传送门2中，当游戏在DirectX 9模式下运行时，无论阴影质量设置如何，在某些显卡上env_projectedtexture都不会渲染阴影。要解决此问题，请在启动参数添加-vulkan，让游戏在Vulkan模式下运行。 [todo tested in ?]Bug:实体绑定在原版SDK代码中无法使用 [todo tested in ?]
Code Fix:可以按照该教程修复此bugEnv_projectedtexture/fixes#Fixing Parenting.
Bug:投射纹理与env_cascade_light之间没有平滑过渡 [todo tested in ?]}}

- 1: Enabled（默认开启）
- 2: Always Update（始终更新，用于移动光源）Template:AS add:zh-cnTemplate:Mapbase also:zh-cn
Keyvalues
- Target (target) <targetname>
- The entity will rotate to point at this target. Make sure you check the Always update flag if you set this.
- FOV (lightfov) <float>
- The field of view cone/pyramid at which the texture is projected.
Confirm:This keyvalue does not work in Alien Swarm.
- NearZ (nearz) <float>
- Objects closer than this will not receive the light from the projection.
- FarZ (farz) <float>
- Objects beyond this distance will not receive the light from the projection.
- Enable Shadows (enableshadows) <boolean>
- Enables/disables shadows from this projected texture. 0 = no, 1 = yes.
- Shadow Quality (shadowquality) <choices>
- Quality of shadows.
- 0: Low (sharp, pixelized shadows)
- 1: High (smooth edged shadows)
- Light Only Target (lightonlytarget) <boolean>
- Limit flashlight effect to only affect target entity.
- Light World (lightworld) <boolean>
- Control whether flashlight affects static world geometry. 0 = no, 1 = yes.
- Camera Space (cameraspace) <integer>
- Angles are interpreted as being relative to camera.
- Appearance (style) <choices> (in all games since
) (also in 
)
- Various Custom Appearance presets. Note:Requires input
AlwaysUpdateOn to work.
- Enable Volumetrics (volumetric) <boolean> (only in )
- Whether or not to use volumetrics for this projected texture.
- Volumetric Intensity (volumetricintensity) <float> (only in )
- Defines the intensity of the volumetrics. (Default is 1. Can go above; no strict limit)
Inputs
Note:In some FGDs, only TurnOn, TurnOff and FOV are present.- TurnOn
- Turns on the texture. Confirm:In gmod projected lights always start on even when "enabled" is not checked.
- TurnOff

- FOV <float>
- Sets FOV.
- EnableShadows <boolean>
- Set the if shadows are enabled. 0 = no, 1 = yes.

- AlwaysUpdateOn (in all games since
) (also in )
- Turn on per frame updating (for moving lights).
- AlwaysUpdateOff (in all games since ) (also in )
- Turn off per frame updating (for moving lights).
- SetBrightness <float> (only in )
- Sets the brightness.
- EnableVolumetrics <boolean> (only in )
- Enables or disables volumetrics.
- SetVolumetricIntensity <float> (only in )
