The properties of any sky keyframe can be changed at any time. However, only HazeEccentricity can be changed for an in-use keyframe without triggering a recalculation of the colour tables.

< Whether to calculate the moon position from the date and time.
Checksum including values not needed for GPU recalculation.
Mie < The time this keyframe represents, in a floating-point number of days from the starting midnight of the sequence. If simul::sky::SkyKeyframer::SetLinkKeyframeTimeAndDaytime is true, this is not used.
Haze < The Mie scattering coefficients (x=red,y=green,z=blue). Mutable because of AutoMie.
HazeBaseKm < The amount of haze, mist or fog.
HazeScaleKm < The base altitude, above which haze starts to decrease in density.
HazeEccentricity < The vertical scale over which haze reduces with altitude.
GroundFog < The anisotropy of Mie scattering. Can be changed without recalculating tables.
FogCeilingKm < Thick ground fog
SunAzimuth < Upper limit of ground fog
SunElevation < Horizontal angle to the sun. This will be overridden if sun position is automatic.
MoonElevation < Angle of the sun above the horizon. This will be overridden if sun position is automatic.
MoonAzimuth < Angle of the moon above the horizon. This will be overridden if moon position is automatic.
SeaLevelTemperatureK < Horizontal angle to the moon. This will be overridden if moon position is automatic.
StoreAsColours < Temperature at sealevel, in kelvins - mainly relevant to infra-red.
Horizon < If true, the keyframe is stored as a colour table, rather than generating its colours from its properties.
automaticSunPosition < Whether to recalculate the Mie coefficients based on the haze at this keyframe.
automaticMoonPosition < Whether to calculate the sun position from the date and time.
