Values greater than 0 enable image-based lighting and specify the image map that should be applied to the environment during rendering.
A negative or 0 value indicates that image-based lighting is disabled. When a negative value is specified, the current image map is retained but not used by the renderer. For example, a value of -3 indicates that the Plaza image map is set current and image-based lighting is disabled.
Valid range of values supported are -11 to 11.
