===What is a lightcookie texture ?===
{{this is a|point entity|name=newLight_Point|game=Black Mesa|sprite=NewLight Point.png}} It creates an invisible [[Deferred lighting|deferred light]] source that shines in all directions, includes godrays and lightcookies.
Lightcookie (a. k. a. "Texture Light") a texture or mask applied to a light source. It is usually used to shape the light's output or fake shadows with specific patterns (which, unlike shadowmaps, can be translucent and look more accurate). It also can be used for stuff like projectors, cautists, disco spheres, etc.

{{Note|You can have only 512 point light entities placed in the map editor.}}


In Black Mesa, it can be used via "'''Texture name for TexLight''' ''(texName)''" property (to specify the texture) and "'''Enable Texture Light''' ''(bTexLight)''" (to enable the feature).

===Texture mask===
The texture mask defines which pixels will display the lighting and also affects their color. Black pixel color will not render the light at all, white will render the light and its color value, other colors (red, blue, yellow, etc.) will be mixed with the light color value, depending on their intensity and how close they are to white. Alpha channel doesn't affect anything, so make sure you don't use it in your texture.  
 
Point lights requires "Environment Map" texture to work with lightcookies, because point lights are using 6 separate faces, so each face requires separate texture. Follow [[$envmap#Creating_a_custom_static_cubemap_texture|these steps]] to create "Environment Map" texture.
 
Spot lights can use any texture basically.
 
It is recommended to use '''No Mipmap''' and '''No Level Of Detail''' flags for your [[VTF]] file, so the texture will not cause aliasing issues.

===Animation===
Spot lights also support 2 different animation types, which allow you to animate a texture in two different ways.
 
====Texture Cookie FPS====
{{todo}}
 
====Texture Cookie Scroll Mode====
In this mode, lightcookie texture can scroll in X and Y directions. This feature can be enabled with '''Tex Cookie Scroll Mode''' (''bTexCookieScrollMode'') property.
 
X direction controlled by '''ScrollSpeedU''' (''fScrollSpeedU'') property. Y direction controlled by '''ScrollSpeedV''' (''fScrollSpeedV'') property. Both takes a float value. The default X direction is left, Y is up. Using a value multiplied by -1 will reverse direction, this allows you to use 8 different scroll directions. 0 means don't move in this direction. The size of the value affects the scroll speed.
 
Here is the [https://youtu.be/FkUFF6CLTq8 video] showcase of all 8 directions and how the feature look like.
 
==Shadow filtering==
Versions of the game before Necro Patch uses PСF filter. The shadow edges are sharper and exhibit a more distinct transition. There are visible aliasing artifacts, particularly on the edges. Shadows from small or thin objects were also indistinguishable. However, it was pretty good for shadows with low resolution, because they looked blurry. The shadows are somewhat similar to those that can be seen from the [[projected texture|projected textures]] in {{portal2|4}}.
<gallery mode=packed heights=410px>
File:shadowfilter_old.jpg| frame |Barney's hand with old shadow filtering.
</gallery>
The Necro Patch replaced PСF filter with PCSS filter. The shadow edges appear smoother and less jagged. The transition from the shadow to the lit area has more gradient-like softening. Shadows have become more detailed for small objects. Because of this, you have to adjust the shadows more carefully.
<gallery mode=packed heights=410px>
File:shadowfilter_new.jpg| frame |Barney's hand with new shadow filtering.
</gallery>
This filter has one significant issue: there is now noticeable noise in the shadows. This is mostly noticeable in low resolution shadows, this spoils them quite a lot (although it makes them more detailed). There is no way to disable this effect. The noise also makes the shadows more similar to shadows from flashlight in {{hl2|4}}. It is worth noting that such thing exists in more modern engines ([https://en.wikipedia.org/wiki/Unreal_Engine Unreal Engine 5] for example), so you can ignore the noise if it's not very noticeable, especially on shadows with high quality.
 
The noise is adjusted via ShadowRadius and ShadowMapLOD values, mainly via ShadowRadius; you even can disable the noise with 0 value, but this will make your shadows will look like stairs/pixels.
<gallery mode=packed heights=310px>
File:shadowfilter_new1.jpg| frame |The noise example.

{{note|It is not entirely clear which term is correct, '''PCSS''' or '''PCCS''', since it could be orgography, but it is possible (though unlikely) that they created their own filter.}}

NewLight_Point in End Game chapter (used for the portal).
Note.pngNote: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.pngNote: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 Obsolete
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.pngNote:With 0 it will make the light disabled, including the effects. Doesn't affect shadows.
Note.pngNote: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.pngWarning:This is one of the parameters that affects performance in the game. Smaller values ​​allow you to process less geometry and save performance.
Icon-Important.pngImportant:Range is limited, the limit depends on intensity value. Do not use values ​​bigger than the intensity value allows.
Examples
  • Range - 50
    Range - 50
  • Range - 1000
    Range - 1000
  • Range - 15000
    Range - 15000

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

    ShadowRadius - 0.0001
  • ShadowRadius - 1
    ShadowRadius - 1
  • ShadowRadius - 5
    ShadowRadius - 5

  • SlopeDepthBias - 8
    SlopeDepthBias - 8
  • SlopeDepthBias - 20
    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.pngNote:You will not see any changes if your material doesn't not provide bumpmap.
  • NormalBias - 1
    NormalBias - 1
  • NormalBias - 5
    NormalBias - 5
