Acceleration structure is unknown, possibly overwritten before frame capture [2022.2.1]

Developer Tools Nsight Graphics

Hi,

I’ve been trying to capture a frame from my application and I get the error “Acceleration structure is unknown, possibly overwritten before frame capture”.

If I look in the API Inspector for the DispatchRays event it shows the TLAS there and I can inspect it. However, it’s showing “No shaders” for the Ray Generation (the application functions correctly outside of capture).

Do you have any idea what could cause this to happen?

Thanks,

Mark

Hello,
Thanks for using Nsight Graphics. I spoke to one our Nsight Graphics engineers here and he suggests that you inspect your RayGen table data to ensure it starts with a valid shader id.
Let us know if this helps.
