Template: Select from a predefined list of Lighting Templates. The list of templates can be found and edited under World -> Lighting Templates.
Inherit: Select any of these check boxes to override the parameters from Lighting Template. This will enable the fields below.
Ambient: Select color of the ambient light.
Fog: Select the color of the fog.
Fog Near: Sets the distance at which the fog begins.
Fog Far: Sets the distance at which the fog reaches 100 percent.
Fog Power: Edits the fog's curve. A value of 1 is linear, less that one pushes the curve toward the near value, and a value above 1 pushes the curve toward the far value.
Fog Max: Not used.
Clip Distance: Sets the distance of the clipping plane in an interior. Anything past this value will not be displayed.
Directional: Select color of directional light.
Rotation: Sets the angle of the directional light.
Fade: Sets the fade distance of the light.
Show Sky: If checked, enables sky and weather as if this cell was an exterior.
Use Sky Lighting: Whether the sky's lighting conditions should affect the lighting in the cell.
Light Fade Distances: The distance at which regular omni lights start to fade out and when they are faded out completely. This has no impact on shadow casters.
If the "begin" distance is set to zero, then the game pulls a default value from the INI files — specifically, the fLightLODStartFade setting from the Display setting. If the "end" distance is set to zero, then it defaults to fLightLODStartFade plus fLightLODRange.
