USTRUCT()
struct FSimulationStageMetaData

Variables

		Name	Description
	uint32: 1	bPartialParticleUpdate	When enabled the simulation stage does not write all variables out, so we are reading / writing to the same buffer.
	uint32: 1	bParticleIterationStateEnabled
	uint32: 1	bWritesParticles	Do we write to particles this stage?
	FName	EnabledBinding
	ENiagaraSimStag...	ExecuteBehavior	Controls when the simulation stage will execute.
	FIntVector	GpuDispatchNumThreads	When in custom mode this is the num threads.
	ENiagaraGpuDisp...	GpuDispatchType	Dispatch type set for this stage.
	FName	IterationSource	The Data Interface that we iterate over for this stage. If None, then use particles.
	int32	NumIterations	The number of iterations for the stage.
	FName	NumIterationsBinding	Optional binding to gather num iterations from.
	TArray< FName >	OutputDestinations	DataInterfaces that we write to in this stage.
	FName	ParticleIterationStateBinding	When the value is not none this is the binding used for particle state iteration stages.
	int32	ParticleIterationStateComponentIndex	Cached component index for particle iteration stage.
	FIntPoint	ParticleIterationStateRange	Inclusive range to compare the particle state value with.
	FName	SimulationStageName	User simulation stage name.
