The Chrome texture creates a simple but effective environment to emit convincing reflections. The basic environment map consists of a ground plane and a sky plane. To add visual complexity to the scene, a series of rectangular lights are included in the sky. These lights are for visual effect only and do not act as light sources.
There is no blurring capability for the Chrome procedure, so aliasing artifacts may appear on reflective surfaces. These may be greatly reduced by having an aalevel of 4 and an aathreshold of 0 when rendering. An alternative is to use Chrome to create the faces for the Cube procedure.
