AtmosphereFromGround

The AtmosphereFromGround { } subnode of the Atmosphere { } node describes the atmosphere’s color when seen in LocalSpace.

Example

Atmosphere
{
	AtmosphereFromGround
	{
		DEBUG_alwaysUpdateAll = False
		doScale = True
		waveLength = 0.864102423, 0.807692051, 0.650640965, 0.5
		samples = 4
		innerRadiusMult = 0.975
		outerRadiusMult = 1.025
	}
}

Property	Format	Description
DEBUG_alwaysUpdateAll	Boolean	Whether all parameters should get recalculated and reapplied every frame.
doScale	Boolean	Whether the atmosphere mesh should be scaled automatically.
innerRadius	Float	The lower bound of the atmosphere effect in 1/6000ths of a meter.
outerRadius	Float	The upper bound of the atmosphere effect in 1/6000ths of a meter.
invWaveLength	BandOffset	The inverse wavelength. Either this OR `waveLength` should be used. The inverse wavelength is equivalent to each of the color values of the `waveLength` as x: `1/(x^4)` with an alpha of 0.5.
waveLength	BandOffset	The wavelength of the atmosphere. Either this OR `invWaveLength` should be used. The wavelength is equal to each of the color values of the `invWaveLength` as x: `sqrt(sqrt(1/x))` with an alpha of 0.5.
samples	Single	?
transformScale	Vector3	The scale of the atmosphere mesh in all three directions. Automatically set if `doScale` is enabled. If this is set, then `doScale` is set to false automatically.
innerRadiusMult	Float	A multiplier that automatically sets innerRadius based on the planet’s radius. Replaces `innerRadius`.
outerRadiusMult	Float	A multiplier that automatically sets outerRadius based on the planet’s radius. Replaces `outerRadius`.

BandOffset is an input type unique to AtmosphereFromGround and is not strictly a color. Instead, it is the amount a series of specifically-colored bands are offset up and down. The way in which these bands overlap determine the atmosphere color. Note that in waveLength, a value of 1 means the band is all the way down.
