Functions

	Name	Description
FLinearColor	GetColor()	Get light color on linear mode
double	GetIesBrightnessScale()	Get the Ies brightness multiplier
const TCHAR ...	GetIesFile()	Get the path of the Ies definition file - DEPRECATED in 4.26: Replaced with GetIesTexturePathName
FQuat	GetIesRotation()	Get the rotation applied to the IES shape
const TCHAR ...	GetIesTexturePathName()	Get the IES texture path
double	GetIntensity()	Get light intensity
TSharedPtr< ...	GetLightFunctionMaterial()	Get emissive material on this light
double	GetTemperature()	Get the light temperature in Kelvin
bool	GetUseIes()	Set if this light is controlled by Ies definition file
bool	GetUseIesBrightness()	Get if the emissive amount of the ies is controlled by the brightness scale
bool	GetUseTemperature()	Get if the light color is controlled by temperature
bool	IsEnabled()	Return true on light enabled, false otherwise
void	SetColor ( FLinearColor Color )	Set light color on linear mode
void	SetEnabled ( bool bIsEnabled )	Set enable property of the light
void	SetIesBrightnessScale ( double IesBrightnessScale )	Set the Ies brightness multiplier
void	SetIesFile ( const TCHAR* IesFile )	Set the path of the Ies definition file - DEPRECATED in 4.26: Replaced with SetIesTexturePathName
void	SetIesRotation ( const FQuat& IesRotation )	Set the rotation to apply to the IES shape
void	SetIesTexturePathName ( const TCHAR* TextureName )	Set the IES texture path The path is either the name of an element attached to the scene or the path of a UE texture asset, i.e. /Game/.../TextureAssetName.TextureAssetName
