yes im using the same 12 device to 12device 5 for RT

I never did find a solution. So, I'm just increasing the texture size so that it's square. Once the compute is done, I crop back to rectangular from square. With OpenCV, it's easy.

Can't figure out how to read back data from an AppendStructuredBuffer in a compute shader in UE5.2.

I have this simple shader which fills an AppendStructuredBuffer with 1s:

AppendStructuredBuffer<int> OutputAppendBuffer;

[numthreads(THREADGROUPSIZE_X, THREADGROUPSIZE_Y, THREADGROUPSIZE_Z)]

What ^ @joej said. But I'll add a personal axiom that if it's atomic and it's not an index or a counter … you probably need to think again. It applies to all atomics but Compared (min/max) atomics (like an atomic ray-hit distance) are the more obvious example of how atomics can become problems in h…

Hi! Guys! Recently,I am trying to write a PBR pipeline in my DirectX12 app.And I use compute shader to generate irradiance IBL , specular IBL and BRDF Lut before app running. Although the app spent much time to initialize,the app can run well. But after I run the app several times, when I run my ap…
