Note:You can have only 512 point light entities placed in the map editor.

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.

See also: Generic Keyvalues, Inputs and Outputs available to all entities

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

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.

Note:There is almost no differences if you're using point light with no texture. Things changes if you're using textures.

Use old Falloff ? (bUseOldFallOff) <choices> !FGD 

Deprecated.
Sets old falloff state, disabled or enabled. This feature is disabled in the code, so you can't use old falloff (although it is still used for the flashlight).

• 0: Disabled
• 1: Enabled

Light Color (LightColor) <color255>

The RGB color of the light. Colors must be between 0 and 255.

Light Intensity (Intensity) <float>

Intensity/brightness of the light. It's RGB * intensity.

Note:With 0 it will make the light disabled, including the effects. Doesn't affect shadows.

Note:The default 8000 value is equivalent to default 200 brightness value for static VRAD lights. If needed to repeat static light brightness, multiple the brightness value by 40; if vice versa, divide by 40.

Range (Range) <float>

Range of the light, or how far the light source can illuminate. Measured in Hammer Units.

Warning:This is one of the parameters that affects performance in the game. Smaller values ​​allow you to process less geometry and save performance.

Important:Range is limited, the limit depends on intensity value. Do not use values ​​bigger than the intensity value allows.

Examples

Range - 50 Range - 1000 Range - 15000

Enabled (Enabled) <choices>

Sets light state on spawn, enabled or disabled.

• 0: Enabled
• 1: Disabled

Appearance (style) <integer choices>

Appearance presets.

4	Fast strobe	mamamamamama
9	Slow strobe	aaaaaaaazzzzzzzz
12	Underwater light mutation	mmnnmmnnnmmnn

Tip:Use new lights instead for lights with custom appearance, because static lightmapped lights reduces performance with this feature (especially near displacements).

Note:Custom light styles are not possible.

Light Ambient Color (LightColorAmbient) <color255>

The RGB color of the shadows. Colors must be between 0 and 255.

Examples

0 0 0 0 0 255 255 168 168

SpecularMultiplier (SpecMultiplier) <float>

Examples

0.5 1 2

falloffConstant (falloffConstant) <integer> !FGD 

Deprecated.
Constant value (can work only if old falloff is enabled).

falloffLinear (falloffLinear) <integer> !FGD 

Deprecated.
Linear value (can work only if old falloff is enabled).

falloffQuadratic (falloffQuadratic) <integer> !FGD 

Deprecated.
Quadratic value (can work only if old falloff is enabled).

Light Type (LightType) <choices>

Type of the light. This affects the behavior of the light source with parent, enable/disable dynamic models in shadowmaps, enable/disable static shadowmaps.

• 0: Static - used only static shadowmaps, this means that shadows are cast only by static objects (prop_static, geometry, etc). Cannot move with parent.

Important:Brush entities and bmodels are also included in static shadowmaps and they never update (including func_physbox).

Note:Static shadowmaps will update after save reload (only once).

• 1: Stationary - the same as Static, but with dynamic shadows for dynamic models.
• 2: Dynamic - lighting don't use static shadowmaps at all. It uses dynamic shadows for static objects and dynamic models. This type also can move with parent. This type is expensive, usually used for moving lights, but also can be used if you're getting issues due to static shadowmaps.

Examples

Note:Note that shadow from metal box and grate box are flying on first and second pictures, that's because both was placed in air on map spawn. Doesn't happen on third picture, because the light updated shadow for both. Static Stationary Dynamic

HasShadow (HasShadow) <choices>

Sets shadows state for the light, enabled or disabled. Remember that the default choices is No.

• 0: No
• 1: Yes

Examples

Has Shadow - NO Has Shadow - YES

ShadowMapLOD (ShadowLod) <choices>

Resolution of shadowmap used by this light. This affects the quality of the shadows.

• 0: 256
• 1: 512
• 2: 1024

Examples

256 512 1024

Important:You cannot use any value from here an unlimited number of times. More information below.

ShadowRadius (ShadowRadius) <float>

Radius of shadow edges for soft shadows. If its value is negative, code will auto assign a value depending on ShadowLod. These code based values can be adjusted via convars nr_shadow_rad_High, nr_shadow_rad_Med and nr_shadow_rad_Low.

Examples

ShadowRadius - 0.0001 ShadowRadius - 1 ShadowRadius - 5

Tip:Don't use very low values, because the shadows will look like stairs. Also don't use very high values, because the noise will spoil them a lot, or you'll see only noise.

NearZ (NearZ) <float>

NearZ used by shadowmap camera for this light. This is the distance at which the light source will start cast shadows.

ShadowFaceX (ShadowFaceX) <choices>

Sets shadow state (enabled or disabled) for X face.

• 0: Enabled
• 1: Disabled

ShadowFaceX_Minus (ShadowFaceX_Minus) <choices>

Sets shadow state (enabled or disabled) for -X face.

• 0: Enabled
• 1: Disabled

• 0: Enabled
• 1: Disabled

Sets shadow state (enabled or disabled) for -Y face.

• 0: Enabled
• 1: Disabled

ShadowFaceZ (ShadowFaceZ) <choices>

Sets shadow state (enabled or disabled) for Z face.

• 0: Enabled
• 1: Disabled

SlopeDepthBias (SlopeDepthBias) <float>

Slope Depth Bias used for surfaces having aliasing due to steep angles with light.

Examples

SlopeDepthBias - 0.2 SlopeDepthBias - 8 SlopeDepthBias - 20

NormalBias (NormalBias) <float>

While rendering objects into shadowmaps, each vertex will be moved along -ve Normal direction, giving it an appearance of shrinking while rendering to shadowmaps. This property determines the amount of Units to be moved. Helps with shadow aliasing.

Examples

Note:You will not see any changes if your material doesn't not provide bumpmap. NormalBias - 1 NormalBias - 5 NormalBias - 20

Important:Increasing this value will make shadows between different surfaces less accurate, greate example is third picture in examples, there you can see "two" shadows from railing.

Bug:Numbers lower than 0.8 can cause huge graphics issues. Example.

Tip:Increase this value if you are getting aliasing issues like this.

Enable Texture Light (bTexLight) <choices>

Sets lightcookie (texture lights) state, enabled or disabled.

• 0: Disabled
• 1: Enabled

Examples

Disabled Enabled

Warning:This is one of the most expensive features, use wisely.

• 0: Disabled
• 1: Enabled

LightnGodRayMode (LightnGodRayMode) <choices>

This determines what effects will be available to use for the light source. Keep in mind that the default choice is Light.

• 0: Light - light only.
• 1: Godrays - godrays only.
• 2: Both Light and GodRays - both light and godrays.

Bug:Even if godrays is turned off, the game will still think that the godrays is used if choice is Godrays or Both Light and GodRays.

EnableGodRays (EnableGodRays) <choices>

Sets godrays state on spawn, enabled or disabled.

• 0: Disabled
• 1: Enabled

Warning:You can have only 40 point lights with godrays enabled simultaneously, otherwise the game will crash with this error message.

The error
