Variables

  Type Name Description
Public variable bool bNeedsPrevFrameData  
Public variable int32 CurrBufferAccessCounts Track current read/write counts +ve for readers, -ve for writers. We cannot mix readers and writers in the same buffer in the same stage.
Public variable FNiagaraDataBufferRef CurrFrameData  
Public variable FString DebugName  
Public variable FNiagaraGpuComputeDispatchInterface * DispatchInterfaceForDebuggingOnly  
Public variable FNiagaraDataSet * GPUDataSet  
Public variable FNiagaraDataChannelLayoutInfoPtr LayoutInfo Keeping layout info ref to ensure lifetime for GPUDataSet.
Public variable TWeakPtr< FNiagaraDataChannelData > Owner  
Public variable TArray< FNiagaraDataBufferRef > PendingCPUBuffers Buffers coming from the CPU that we're going to copy up for reading on the GPU.
Public variable int32 PendingGPUAllocations Users that need space in this NDC Data add to this for each tick via AddGPUAllocationForNextTick().
Public variable TArray< FNDCGpuReadbackInfo > PendingGPUReadbackBuffers Buffers written from the GPU that we must send back to the CPU.
Public variable FNiagaraDataBufferRef PrevFrameData
