Lights
Lights are objects that simulate real lights such as household or office lamps, the light instruments used in stage and film work, and the sun itself. Different kinds of light objects cast light in different ways, emulating different kinds of real-world light sources.

Materials describe how an object reflects or transmits light. Within a material, maps can simulate textures, applied designs, reflections, refractions, and other effects. (Maps can also serve as environments and projections from lights.)
