Adding light to a level is one of the key steps of creating a beautiful and complete map. Lighting shouldn't be used solely to provide light to your work, but to create atmosphere, enhance textures, and complement textures.

Let There Be Light!
To add a light to your map do one of the following:
- Right-click the surface you want the light to appear on, and select Surface Context Menu -> Add Light here.
- Hold down the L key and left-click in a 3D Viewport.
Positioning Lights
Once you have lights in a map you can duplicate them the same as any other actor. You can move the light easlily with Control + left mouse in the 2D viewports. It can also be moved in the 3D viewport, but the mouse control is a little more involved.
Approximate Versus Exact Light
Although lighting will appear to show while inserting lights into a map, the light is approximate should you change its properties or move it. To get a correct render of the lights, rebuild your map: click on the little 'lightBulb' icon in the UnrealEd toolbar.
Changing Light Properties
The procedure for changing a lights' property is:
- Right-click the light and go to the Actor Properties Window
- Expand the property
- Drag the slider with the mouse or enter a number

ViKTiM: I have found that a lot of lights with a colour saturation of 0 screw your frame rate considerably, USE THEM SPARINGLY!!
Tarquin: Great :D Should we link Actor/Lighting too?
Sobiwan: I dunno; I dont use UT2k3. :(
Shuriken: Half updated table for 2k3... don't do much lighting though, so don't know it all.
