Property Value

Type: Vector3F
The color at the horizon when there is no sunlight. The default value is (0, 0, 0).

BaseHorizonColor, BaseZenithColor and BaseColorShift create a color gradient in the sky which is added to the result of the atmospheric scattering computations. These properties basically define the color of the sky in sunless nights: The sky at the horizon will have the BaseHorizonColor. The zenith will have the BaseZenithColor. All other base sky colors are interpolated between those two colors. BaseColorShift determines where the sky color is exactly the average of both colors. If BaseColorShift is 0.5, the average color of the gradient is in the middle of the top hemisphere. If this value is less than 0.5, then the average color is shifted down to the horizon. If this value is greater than 0.5, then the average color is shifted up to the zenith.
