Variables

Type	Name	Description
FNiagaraDataSetAccessor< int32 >	ArrayIndexAccessor
FNiagaraVariableAttributeBinding	ArrayIndexBinding	Which attribute should we use to pick the element in the geometry cache array for this renderer? If not set, a random element will be used.
bool	bAssignComponentsOnParticleID	If true then components will not be automatically assigned to the first particle available, but try to stick to the same particle based on its unique id.
bool	bIsLooping	If true, then the geometry cache keeps playing in a loop
uint32	ComponentCountLimit	The max number of components that this emitter will spawn or update each frame.
FNiagaraDataSetAccessor< float >	ElapsedTimeAccessor
FNiagaraVariableAttributeBinding	ElapsedTimeBinding	Which attribute should we use for the geometry cache's current animation time?
FNiagaraDataSetAccessor< FNiagaraBool >	EnabledAccessor
FNiagaraVariableAttributeBinding	EnabledBinding	Which attribute should we use to check if rendering should be enabled?
TArray< FNiagaraGeometryCacheReference >	GeometryCaches	Reference to the geometry cache assets to use.
FNiagaraRendererMaterialParameters	MaterialParameters	If this array has entries, we will create a MaterialInstanceDynamic per Emitter instance from Material and set the Material parameters using the Niagara simulation variables listed.
FNiagaraDataSetAccessor< FNiagaraPosition >	PositionAccessor
FNiagaraVariableAttributeBinding	PositionBinding	Which attribute should we use for the geometry cache position?
int32	RendererVisibility	If a render visibility tag is present, particles whose tag matches this value will be visible in this renderer.
FNiagaraVariableAttributeBinding	RendererVisibilityTagBinding	Which attribute should we use for the renderer visibility tag?
FNiagaraDataSetAccessor< FVector3f >	RotationAccessor
FNiagaraVariableAttributeBinding	RotationBinding	Which attribute should we use for the geometry cache rotation?
FNiagaraDataSetAccessor< FVector3f >	ScaleAccessor
FNiagaraVariableAttributeBinding	ScaleBinding	Which attribute should we use for the geometry cache component scale?
ENiagaraRendererSourceDataMode	SourceMode	Whether or not to draw a single element for the Emitter or to draw the particles.
FNiagaraDataSetAccessor< int32 >	UniqueIDAccessor
FNiagaraDataSetAccessor< int32 >	VisTagAccessor
