Views over Append/Consume buffers in Direct3D 11

Question

I'm using append/consume buffers to reduce shading work in my path-tracer (immediately shade empty space + emitters in a pre-pass, append the remaining pixels for full processing), and I've heard that I should be using a UAV when I'm accessing through AppendStructuredBuffer<T> and an SRV when I'm accessing through ConsumeStructuredBuffer. I haven't seen that claim in any of Microsoft's documentation, but it might explain why my calls to [Consume()] are returning empty data - is it accurate?

Answer 1

I should have tested myself before I asked - shaders with ConsumeStructuredBuffers declared in SRV registers (tN) fail to compile and emit an error saying they're only bindable through UAVs.

My AppendStructuredBuffer bound through the UAV registers works fine, so it seems like I was just quoting hearsay; unordered-access-views should be used for both HLSL types.
