Hello, My latest questions are: [image] OptiX launch dimension inquiry OptiX Hello, Previous question: Is there a way to know how much GPU memory Optix will use? If the number of meshes is small, it runs, but if there are a lot, it does not run, so I thought…

I’ve answered exactly that in Method A here before: https://forums.developer.nvidia.com/t/whats-your-solution-to-get-all-hit-primitives-of-multiple-rays/239528/2 Read the comment on atomic congestion there to find the faster matrix addressing. Not sure what visibility tests you’re implementing ex…

I’ll refer to the link. I think it will help you a lot. Thank you.

If you’re really only determining the visibility between triangles, there is an exact number of results, which is a different case than the “which rays hit which primitives” inside the linked post. You wouldn’t need atomics to write the bit results in that case. Instead you could let each each laun…
