effect by changing the background color at a nonzero frame with the Auto
Key button on.
Environment Map The button for Environment Map on page 7768 displays
the name of the map, or “None” if none has been assigned. The map must
use Environmental mapping coordinates on page 7838 (spherical, cylindrical,
shrink wrap, and screen).
To assign an environment map, click the button and use the Material/Map
Browser to choose a map, or drag a map from a sample slot or map button in
the Material Editor (or anywhere else in the software; for example, a Projector
Map button) and drop the map on the Environment Map button. A dialog
asks if you want the environment map to be a copy (independent) or an
instance of the source map.
NOTE If your scene includes animated bitmaps, including materials, projector
lights, environments, and so on, the animation file is reloaded once per frame.
Rendering performance slows down when your scene uses multiple animations,
or the animations are themselves large files.
To adjust the environment map's parameters, for example to assign a bitmap
or change the coordinate settings, open the Material Editor, drag the
Environment Map button, and drop it over an unused sample window.
Use Map Uses a map for the background rather than the background color.
Global Lighting group
Tint Tints all lights in the scene (except for ambient light) if this color is
anything other than white. Click the color swatch to display the Color Selector,
on which you can choose the tint color. You can animate the tint color by
changing it at a nonzero frame with the Auto Key button on.
Level Multiplies all lights in the scene. A Level of 1.0 preserves the original,
individual light settings. Increasing the Level raises the lighting for the overall
scene, and decreasing the Level lowers the overall lighting. This parameter is
animatable. Default=1.0.
Ambient Sets the color for the ambient light. Click the color swatch, and
choose the color you want in the Color Selector. You can animate the light
effect by changing the ambient light color at a nonzero frame with the Auto
Key button on.
