Syntax

void CopyRayTracingGPUInstances
(
    FRHICommandList & RHICmdList,
    uint32 InstancesCount,
    int32 DescBufferOffset,
    FRHIShaderResourceView * TransformsSRV,
    FRHIUnorderedAccessView * InstancesDescUAV,
    TFunctionRef< void *, const FShaderResourceParameter &, const FShaderResourceParameter &, bool)> ResourceBindCallback
)

Remarks

CS can be dispatched from inside low level RHIs via FRHICommandList_RecursiveHazardous. ResourceBindCallback is provided to allow the RHI to override how the UAV resource is bound to the underlying platform context.
