newLight_Point

newLight_Point is a point entity available in Black Mesa.

This article has multiple issues. Please help improve it or discuss these issues on the talk page. (Learn how and when to remove these template messages)

It is one of the many new lighting entities available. Black Mesa incorporates a new lighting system which utilizes Deferred lighting to create dynamic lighting system with dynamic shadows, which allows to complement and quite enliven some scenes, it is also nice effect for moving objects, such as trains. It is also include fine tuning Godrays and lightcookies.

Warning:New lights use expensive gbuffer, that means that with this entity your scene rendering at least 5 times, which makes your level very expensive, considering that XenEngine uses 32-bit architecture and DirectX 9.5 rendering. In large quantities, new lights can greatly heat up your computer and also cause large FPS drops (depending on difficulty of your map and how your area open). Use wisely.

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.
Parent (parentname) <targetname>: The name of this entity's parent in the movement hierarchy. Entities with parents move with their parent.
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.; Important:Have huge differences if you use texture for your newLight_Point.
Enabled (Enabled) <choices>: Enable/Disable this Entity.

Determines if the light is off at level start.

0: Enabled
1: Disabled

Appearance (FlareStyle) <choices>: Appearance presets.

Tip:Static lightmapped lights reduces performance with custom appearance (especially near displacements). If this cause problems, you can use replace your static lights with new lights, if used correctly - in most cases this will significantly preserve performance.

Light Color (LightColor) <color255>: This is the color of the sunlight.

Determines color of light.

Light Ambient Color (LightColorAmbient) <color255>: This is the ambient color of the sunlight.

Determines color of shadows that light source creates.

Examples
0 0 0 255 0 0 255 128 128

Light Intensity (Intensity) <float>: RGB * Intensity.

Brightness of the light.

Note:With 0 will not draw, process and specular shader be disabled.
SpecularMultiplier (SpecMultiplier) <float>: 0 to 1 RGB * Intensity * SpecularMultiplier.

Brightness of the specular shader from this light source.

Examples
SpecularMultiplier - 1 SpecularMultiplier - 10 SpecularMultiplier - 20

Range (Range) <float>: How far the light source illuminates. Measured in Hammer Units.; Important:It greatly affects optimization, less is better.

Examples
Range - 150 Range - 300 Range - 500

Light Type (LightType) <choices>: Determines the light type.

0: Static - shadows are cast only by static objects (prop_static, geometry, etc.). Lighting does not update if it has parent (use if part scene has no large moving parts, or shadow accuracy is not important).
1: Stationary - shadows are cast by static and dynamic objects, lighting does not update if it has a parent.

Important:Shadows for dynamic props update, but baked for geometry. That means that shadows from func_physbox and other dynamic geometry will never update, and shadows from other geometry on them too.

2: Dynamic - lighting is not baked at all. Shadows are cast by static and dynamic objects, lighting updates if it does have a parent. This light is quite expensive, and should only be used for moving light sources, or if your scene have moving geometry.

Examples
Light Type - Static Light Type - Stationary Light Type - Dynamic

HasShadow (HasShadow) <choices>: Do you want this light to have shadows?

Determines whether the light source will cast shadows. Remember that 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.

Determines quality of shadows. 1024 is very expensive, use it only in places where it's really needed, in most cases 512 is good alternative. 256 produces the blurriest shadows, but it is also the cheapest.

0: 256
1: 512
2: 1024

Examples
256 512 1024
