Public Member Functions
Functions
void	SetbAffectsTranslucency (bool Value)
	Whether lights from this renderer should affect translucency. Use with caution - if enabled, create only a few particle lights at most, and the smaller they are, the less they will cost.
void	SetbAlphaScalesBrightness (bool Value)
	When checked, will treat the alpha value of the particle's color as a multiplier of the light's brightness.
void	SetbOverrideInverseExposureBlend (bool Value)
	When enabled we will override the project default setting with our local setting.
void	SetbUseInverseSquaredFalloff (bool Value)
	Whether to use physically based inverse squared falloff from the light. If unchecked, the value from the LightExponent binding will be used instead.

Public Attributes
Light Rendering
float32	RadiusScale
	A factor used to scale each particle light radius.
float32	DefaultExponent
	The exponent to use for all lights if no exponent binding was found.
float32	SpecularScale
	The specular scale to use for all lights if no binding was found.
FVector3f	ColorAdd
	A static color shift applied to each rendered light.
float32	InverseExposureBlend
	Blend Factor used to blend between Intensity and Intensity/Exposure. This is useful for gameplay lights that should have constant brighness on screen independent of current exposure. This feature can cause issues with exposure particularly when used on the primary light on a scene, as such it's usage should be limited.
int	RendererVisibility
	If a render visibility tag is present, particles whose tag matches this value will be visible in this renderer.
ENiagaraRendererSourceDataMode	SourceMode
	Whether or not to draw a single element for the Emitter or to draw the particles.
Public Attributes inherited from UNiagaraRendererProperties
int	SortOrderHint
	By default, emitters are drawn in the order that they are added to the system. This value will allow you to control the order in a more fine-grained manner. Materials of the same type (i.e. Transparent) will draw in order from lowest to highest within the system. The default value is 0.
ENiagaraRendererMotionVectorSetting	MotionVectorSetting
	Hint about how to generate motion (velocity) vectors for this renderer.
bool	bAllowInCullProxies
FNiagaraPlatformSet	Platforms
	Platforms on which this renderer is enabled.
