Remarks

A light component which emits light from a single point equally in all directions.

Variables

	Name	Description
uint32: 1	bUseInverseSquaredFalloff	Whether to use physically based inverse squared distance falloff, where AttenuationRadius is only clamping the light's contribution.
float	LightFalloffExponent	Controls the radial falloff of the light when UseInverseSquaredFalloff is disabled.
float	SoftSourceRadius	Soft radius of light source shape.
float	SourceLength	Length of light source shape.
float	SourceRadius	Radius of light source shape.

Constructors

Overridden from ULightComponent

	Name	Description
float	ComputeLightBrightness()	Compute current light brightness based on whether there is a valid IES profile texture attached, and whether IES brightness is enabled
FLightSceneP...	CreateSceneProxy()
ELightCompon...	GetLightType()
float	GetUniformPenumbraSize()
void	SetLightBrightness ( float InBrightness )	Set the Intensity using the brightness. The unit of brightness depends on the light type.

Overridden from UObject

	Name	Description
bool	CanEditChange ( const FProperty* InProperty )	Called by the editor to query whether a property of this object is allowed to be modified.
void	PostEditChangeProperty ( FPropertyChangedEvent& PropertyCha... )	Called after property has changed via e.g. property window or set command.
void	PostInterpChange ( FProperty* PropertyThatChanged )	This is called when property is modified by InterpPropertyTracks
void	Serialize ( FArchive& Ar )	Handles reading, writing, and reference collecting using FArchive.
