Light

The Light { } subnode of the ScaledVersion { } node describes the light quality of the star itself.

Property	Format	Description
sunFlare	File Path	The path to an asset bundle containing a Unity LensFlare object that should be applied to the star.
sunlightColor	Color	The color of the LocalSpace starlight. Influences vessels and PQS terrain.
sunlightIntensity	Decimal	The intensity of the LocalSpace starlight. Usage not recommended, because of a lacking distance limit. Use IntensityCurve instead.
sunlightShadowStrength	Decimal	The strength of the shadows caused by LocalSpace starlight.
scaledSunlightColor	Color	The color of the ScaledSpace starlight. Influences the ScaledSpace representation of the bodies.
scaledSunlightIntensity	Decimal	The intensity of the ScaledSpace starlight. Usage not recommended, because of a lacking distance limit. Use ScaledIntensityCurve instead.
IVASunColor	Color	The color of the starlight in IVA view.
IVASunIntensity	Decimal	The intensity of the IVA starlight. Usage not recommended, because of a lacking distance limit. Use IVAIntensityCurve instead.
ambientLightColor	Color	The color of ambient lighting when orbiting near the star.
sunLensFlareColor	Color	The color of the star's LensFlare effect. Gets multiplied with the color of the base texture (yellow-ish for stock flare).
givesOffLight	Boolean	Whether the star should emit light and have a LensFlare effect, or whether it's an object like a black hole.
sunAU	Decimal	Distance in meters. ?Something to do with setting AU from parent star to home world? What's it for? we know it does not affect star luminosity calculation.
luminosity	Decimal	Misnomer. Insolation in watts per square meter at Kerbin's orbit. Calculate for other stars as the (starLuminosity)^0.5 * 1360, where starLuminosity = 1 is the starLuminosity of the stock sun (roughly 1/100th the luminosity of the real world sun). You can use it to calculate the starLuminosity by 4 * Math.PI * kerbinAU * kerbinAU * luminosity.
insolation	Decimal	?value modifying luminosity for power reaching surface?
radiationFactor	Decimal	?Description here?
brightnessCurve	FloatCurve	Associates a distance value with a multiplier for the brightness of the LensFlare effect. The distances are measured in 1/AU value, with 0 being the farthest. See the example above for more info.
IntensityCurve	FloatCurve	Associates a distance value (in meters) with a value that describes the intensity of the LocalSpace starlight at that point.
ScaledIntensityCurve	FloatCurve	Associates a distance value (in meters / 6000) with a value that describes the intensity of the ScaledSpace starlight at that point.
IVAIntensityCurve	FloatCurve	Associates a distance value (in meters) with a value that describes the intensity of the IVA starlight at that point.
