Lights are used to illuminate objects in a scene. Different kinds of light objects cast light in different ways, emulating different kinds of real-world light sources. There are three types of lights in Awakening: point lights, spotlights, and directional lights.
A light bulb, a flashlight, the sun are good examples of them. When there are no lights in a scene, the scene is rendered with default lighting. But if you create a light, the default lighting will turns off.
