The Plaza map, with Light Map enabled.


The same map, with Light map disabled.

Light Map is a feature of GunZ: The Duel that can be accessed through the Options menu. Checking the Light Map option will allow the map to be rendered with light sources such as lamps, torches, and the sun in consideration. Thus, Light Map gives the map a more "realistic" look. However, enabling Light Map on some systems can cause dramatic slowdown, and, in the case of custom maps that do not have proper lighting, cause the map to crash or appear totally black.
