       "doc": "An array for configuring the fade-out effect for the front cutoff of content on pitched map views. It contains three values: start, range and final opacity. The start parameter defines the point at which the fade-out effect begins, with smaller values causing the effect to start earlier. The range parameter specifies how long the fade-out effect will last. A value of 0.0 for range makes content disappear immediately without a fade-out effect. The final opacity determines content opacity at the end of the fade-out effect. A value of 1.0 for final opacity means that the cutoff is completely disabled.",
