It casts an extremely accurate shadow map via the tools/skybox texture, acting as a real-time variation of light_environment. This form of lighting is known as Cascaded Shadow Maps, or CSM, which works by rendering very detailed shadow maps which becomes a lower and lower resolution depending on the distance the viewer is from the surface, similar to mipmaps. Some games automatically add this entity to the map, but it can be placed manually as well.
Note:'s implementation is different from 's. It may work differently than expected.Bug:In , Lightstyles will break when this entity exists. [todo tested in ?]Note:You still need to have a light_environment in your map as well to create lightmap based lighting, which is not done by this entity.Note: Half-Life 2 based games and mods dont have this entity, but you can use community recreation from this github Represented by class CCascadeLight.
Keyvalues
- Light Color (color) <color255>
- This is the color of the sunlight. For , the color is automatically copied from the light_environment.
- Max shadow distance (maxshadowdistance) <float>
- Maximum dynamic shadow distance. Higher values are slower, default on PC is 400 units.
- Use light_environment's angles (uselightenvangles) <boolean>
- If true, the CSM shadow angles are automatically taken from a light_environment's angles. If false, this entity's Pitch Yaw Roll is used.
- LightRadius1 (LightRadius1) to LightRadius3 <float> (only in )
- Used for controlling shadow softness in cascades 1, 2, and 3.
- Depthbias1 (Depthbias1) to Depthbias3 <float> (only in )
- DepthBias for cascades 1, 2, and 3.
- Slopescaledepthbias1 (Slopescaledepthbias1) to Slopescaledepthbias3 <float> (only in )
- Slope DepthBias for cascades 1, 2, and 3.
- ViewModelDepthbias (ViewModelDepthbias) <float> (only in )
- DepthBias for viewmodel cascade.
- ViewModelSlopescaledepthbias (ViewModelSlopescaledepthbias) <float> (only in )
- DepthBias for viewmodel cascade.
- CSM_Volume_Mode (CSMVolumeMode) <choices> (only in )
- Use Manual mode for better quality and performance. In near future Auto mode will be removed from the game.
- 0: Auto: Static cache will update once every 10 frames (approx) covering max shadow distance or whole map around player.
- 1: Manual : Static cache area coverage and updates are managed via CSM Volumes' I/O.
- Start Disabled (StartDisabled) <boolean>
- Stay dormant until activated (with the
Enableinput).
Inputs
- SetAngles <string>
- Sets the direction shadows cast in.
- LightColor <color255>
- Changes color of the sunlight.
LightColorScale!FGD
- Deprecated.
Boosts the color of the sunlight. Non-functional, only resets the Light Color.
- SetCSMVolume (only in )
- Set CSM Volume via trigger volume.
- SetCSMVolumeToSceneBounds (only in )
- Set CSM Volume to scene bounds.
- SetCSMVolumeViaCSMVolumeEntity <targetname> (only in )
- Set CSM Volume to CSM Volume Entity.
EnableDisable:
- Enable / Disable
- Enable/disable this entity from performing its task. It might also disappear from view.
