Fog¶
A keyframe’s haze value determines how much Mie-scattered haze (i.e. mist or fog) is present. Haze is considered to have a density that falls-off exponentially with altitude, so the HazeScaleHeightKm property determines the scaling height for this exponential. TheHazeBaseHeightKm is also used. Below this height, full haze is applied.
