class UParticleModuleLight : public UParticleModuleLightBase

Type	Name	Description
bool	bAffectsTranslucency	Whether lights from this module should affect translucency.
bool	bHighQualityLights	Converts the particle lights into high quality lights as if they came from a PointLightComponent.
uint32: 1	bOverrideInverseExposureBlend	When enabled we will override the project default setting with our local setting.
bool	bPreviewLightRadius	Will draw wireframe spheres to preview the light radius if enabled.
FRawDistributionFloat	BrightnessOverLife	Brightness scale for the light, which can be setup as a curve over the particle's lifetime.
bool	bShadowCastingLights	Whether to cast shadows from the particle lights.
bool	bUseInverseSquaredFalloff	Whether to use physically based inverse squared falloff from the light.
FRawDistributionVector	ColorScaleOverLife	Scale that is applied to the particle's color to calculate the light's color, and can be setup as a curve over the particle's lifetime.
float	InverseExposureBlend	Blend Factor used to blend between Intensity and Intensity/Exposure.
FRawDistributionFloat	LightExponent	Provides the light's exponent when inverse squared falloff is disabled.
FLightingChannels	LightingChannels	Channels that this light should affect.
FRawDistributionFloat	RadiusScale	Scales the particle's radius, to calculate the light's radius.
float	SpawnFraction	Fraction of particles in this emitter to create lights on.
float	VolumetricScatteringIntensity	Intensity of the volumetric scattering from this light. This scales Intensity and LightColor.
