NewLights settings

NewLights_settings is a point entity available in Black Mesa. This entity uses to dynamically change some lighting settings for newLight_Spot and newLight_Point.

Represented by class CNewLightsSettings.

Tip:You can change values dynamically via AddOutput input.

Keyvalues

Name (targetname) <string>[ Edit ]

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.

TargetNewLightEntity_Name (TargetNewLightEntity) <string>

Here you enter name of new light source for which you want to apply changes. Works with multiple lights if they have the same name.

TransitionTime (TransitionTime) <integer>

Transition time in seconds (0 for instant) to transition into new settings. Its a lerp operation A + (B-A) * TimeFactor.

LightType (LightType) <choices>

Type of light source for which you want to apply settings. Entity will not apply settings for spot lights if selected Point Light and will not apply settings for point lights if selected Spot Light.

• 0: Point Light
• 1: Spot Light

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.

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.

Lightstyle presets (epilepsy warning)

Literal Value	Description	Sequence	Preview
0	Normal	m
10	Fluorescent flicker	mmamammmmammamamaaamammma
2	Slow, strong pulse	abcdefghijklmnopqrstuvwxyzyxwvutsrqponmlkjihgfedcba
11	Slow pulse, noblack	abcdefghijklmnopqrrqponmlkjihgfedcba
5	Gentle pulse	jklmnopqrstuvwxyzyxwvutsrqponmlkj
1	Flicker A	mmnmmommommnonmmonqnmmo
6	Flicker B	nmonqnmomnmomomno
3	Candle A	mmmmmaaaaammmmmaaaaaabcdefgabcdefg
7	Candle B	mmmaaaabcdefgmmmmaaaammmaamm
8	Candle C	mmmaaammmaaammmabcdefaaaammmmabcdefmmmaaaa
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>

Specular multiplier. Sets intensity of new specular shader from this light source. It's RGB * Intensity * SpecularMultiplier. 0 means disabled.

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).

OuterAngle (phi) <float>

Outer angle for spot light.

Warning:This affect shadow quality, less is better.

Important:Don't use values 180 and higher, this will make shadows and lighting broken.

InnerAngle (theta) <float>

Inner angle value for spot light.

Warning:Using values higher than in OuterAngle will not make ShadowFOV value higher. This will result in broken shadows.

AngularFallOff (angularFallOff) <float>

Angular falloff value.

Examples

Note:Results depend on values of OuterAngle and InnerAngle. AngularFallOff - 1 (OuterAngle - 60, InnerAngle - 30) AngularFallOff - 30 (OuterAngle - 60, InnerAngle - 30) AngularFallOff - 60 (OuterAngle - 60, InnerAngle - 30)

Inputs

InputApplySettings <void>

Triggers the entity to apply the settings.
