light_omni is a point entity available in SteamVR Home SteamVR Home, Half-Life: Alyx Half-Life: Alyx, and Counter-Strike 2 Counter-Strike 2.

Note.pngNote:(in Counter-Strike 2) light_omni is [Obsolete-notext.png Deprecated]. use light_omni2 instead.

It creates an invisible point light source that can cast both real-time and baked light in all directions. In SteamVR Home SteamVR Home, the real-time component does not cast any shadows, and the number of simultaneously rendered real-time lights are limited to 16.


Keyvalues

Todo: Add any new keyvalues from HL:A.
Todo: Add any new keyvalues from Counter-Strike 2 Counter-Strike 2 .

Source 2 Transform:

Origin (origin) <coordinates>
The world space origin of the entity.
Angles (angles) <angles>
The pitch, yaw, roll orientation of the entity.
Scale (scales) <vector>
The x, y, z scales of the entity. Not all entities can use this.
Transform Locked (transform locked) <boolean>
Lock the transform at its current value, preveting the transform of the node from being modified.
Force Hidden (force hidden) <boolean>
Visually hides the entity from the viewports. The Outliner pane will still list hidden entities.
Editor Only (editor only) <boolean>
Entity is only displayed in Hammer and will not appear in game.


Source 2 Targetname:
Name (targetname) <string>
The targetname that other entities refer to this entity by.
Entity Scripts (vscripts) <scriptlist>
Space delimited list of VScript files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions.
Create Client-Only Entity (clientSideEntity) <choices>
  • 0: No
  • 1: Yes


Source 2 Hierarchy:
Parent (parentname) <targetname>
Specifies a movement parent. An entity will maintain its initial offset from its parent.
Parent Model Bone/Attachment Name (parentAttachmentName) <string>
The name of the bone or attachment to attach to on the entity's parent in the movement hierarchy. Use !bonemerge to use bone-merge style attachment.
Model Attachment position offset (local.origin) <coordinates>
Offset in the local space of the parent model's attachment/bone to use in hierarchy. Not used if you are not using parent attachment.
Model Attachment angular offset (local.angles) <angles>
Angular offset in the local space of the parent model's attachment/bone to use in hierarchy. Not used if you are not using parent attachment.
Model Attachment scale (local.scales) <vector>
Scale in the local space of the parent model's attachment/bone to use in hierarchy. Not used if you are not using parent attachment.
Use Model Attachment Offset (useLocalOffset) <boolean>
Whether to respect the specified local offset when doing the initial hierarchical attachment to its parent.


Source 2 Light:
Enabled (enabled) <boolean>
Sets the initial on/off state of the light.
Color (color) <color255>
The RGB color of the light.
Brightness (brightness) <float>
The brightness of the light. The value can be increased over 1.0
Range (range) <float>
Distance range for light. 0 : infinite.
Cast Shadows (castshadows) <choices>
Whether this light casts shadow.
  • 0: No
  • 1: Yes
  • 2: Baked Only
Shadow Near Clip Plane (nearclipplane) <float>
Distance in game units for near clip plane for shadow map.
Appearance (style) <choices>
Various Custom Appearance presets.
Lightstyle presets

Custom Appearance (pattern) <string>
Set a custom pattern of light brightness for this light. Pattern format is a string of characters, where 'a' is total darkness, 'z' fully bright. i.e. 'aaggnnttzz' would be a steppy fade in from dark to light.
Start Fade Dist (fademindist) <float>
Distance at which the light starts to fade (<0 : use fademaxdist).
End Fade Dist (fademaxdist) <float>
Maximum distance at which the light is visible (0 : don't fade out).
Render to Cubemaps (rendertocubemaps) <boolean>
If true, this geometry renders into baked cube maps
Priority (priority) <integer>
When the number of visible lights exceeds the rendering budget, higher priority lights are chosen for rendering first.
Indirect Light Multiplier (bouncescale) <float>
Multiplies the brightness of light bouncing of surfaces.
Render Diffuse (renderdiffuse) <boolean>
Toggles baking and rendering of diffuse lighting (per-pixel, lightmaps,light probe volumes and bounced light on cubemaps).
Render Specular (renderspecular) <choices>
Controls rendering of direct specular highlights. This applies a bright sphere effect to reflections.
  • 0: Off
  • 1: On - Render in real-time.
  • 2: Bake into cubemaps (Source 1 behavior)
Enabled (directlight) <choices>
How direct lighting should be represented.
  • 0: None
  • 1: Baked
  • 2: Per-Pixel
