Your prepared geometry—including ground surfaces and the facades of all buildings—can have a total surface area of up to 3.5 km².

While we still recommend keeping the ground surface radius to 900 meters or less for optimal performance, you may exceed this if needed, as long as the total combined surface area remains within the 3.5 km² limit.

If you encounter an error, try removing surrounding buildings or geometry that fall outside your project’s area of interest to reduce the total surface area.
