Illuminate a Scene
You can add point lights, spotlights, and distant lights and set the location
and photometric properties of each.
You can use a command to create a light, or you can use a button on the
Lights toolbar or the Lights panel on the ribbon. You can use the Properties
palette to change the color of a selected light or other properties. You can also
store a light and its properties on a tool palette and use it again in the same
drawing or another drawing.
Guidelines for Lighting
The guidelines for lighting used by photographers, filmmakers, and stage
designers can help you set up the lighting for scenes.
Your choice of lighting depends on whether your scene simulates natural or
artificial illumination. Naturally lit scenes, such as daylight or moonlight, get
their most important illumination from a single light source. Artificially lit
scenes, on the other hand, often have multiple light sources of similar
intensity.
