Provides options for controlling the light that envelops objects. Ambient light simulates light scatter in nature, and it is used to soften shadows and simulated natural light shining through a window. When used properly, ambient light can closely simulate a radiosity solution. Ambient light can also be designed for use with scene lighting.
Activate
Uses ambient lighting in the raytraced image. Ambient light affects only those objects that have a value for material ambient reflectivity. Objects that have no ambient reflectivity will not reflect light and could appear black if no additional lights are defined in the scene. Because ambient light is not cumulative, objects in front of a mirror are not brighter than the mirror itself.
Intensity from 0 to 1
Controls the intensity of the ambient light. We recommend a .15 intensity setting.
Color
Controls the color of the ambient light. A recommended setting for this control is white (RGB 255, 255, 255).
Edit
Displays the Color dialog box, allowing you to choose an alternative color for the ambient light.
