GenerateParticleSortKeys()

int32 GenerateParticleSortKeys	(	FRHICommandListImmediate &	RHICmdList,
		FRHIUnorderedAccessView *	KeyBufferUAV,
		FRHIUnorderedAccessView *	SortedVertexBufferUAV,
		FRHITexture *	PositionTextureRHI,
		const TArray< FParticleSimulationSortInfo > &	SimulationsToSort,
		ERHIFeatureLevel::Type	FeatureLevel,
		int32	BatchId
	)

Generate sort keys for a list of particles.

Parameters

KeyBufferUAV	- Unordered access view of the buffer where sort keys will be stored.
SortedVertexBufferUAV	- Unordered access view of the vertex buffer where particle indices will be stored.
PositionTextureRHI	- The texture containing world space positions for all particles.
SimulationsToSort	- A list of simulations to generate sort keys for.

Returns

the total number of particles being sorted.
