fillExtrusionCutoffFadeRange property
This parameter defines the range for the fade-out effect before an automatic content cutoff on pitched map views. Fade out is implemented by scaling down and removing buildings in the fade range in a staggered fashion. Opacity is not changed. The fade range is expressed in relation to the height of the map view. A value of 1.0 indicates that the content is faded to the same extent as the map's height in pixels, while a value close to zero represents a sharp cutoff. When the value is set to 0.0, the cutoff is completely disabled. Note: The property has no effect on the map if terrain is enabled.
Default value: 0. Value range: 0, 1
