Hangs with non-beta NV driver v460.79 and Vulkan SDK 1.2.162.0 about vk_raytrace

Hi there, just to let you know, this sample is hanging for me during startup after the debug statement "Create RtCore" in updatePipeline, specifically : vk_raytrace\rtx_pipeline.cpp (line 134).

The other vulkan KHR ray tracing samples seem to work fine with the mainline nvidia VK drivers, so I figured I'd try it here. No dice.

I can confirm this behavior (2x RTX 2080Ti) same drivers and SDK.

This is a driver bug, commenting the ignoreIntersectionEXT in the AnyHit shader will make the createRayTracingPipelineKHR() to pass, but transparency won't work. A new driver with this fix should be available very soon.

Yay. I'll close this as soon as I get the update. I've had issues with AnyHit stopping working within my own engine when I switched to the mainline drivers so I figured it was part of it. But disabling adding the anyhit shader stage and layout group simply caused a crash later on, in this sample. In my own code, it works but indeed the alpha test stops working. I'll try your workaround in the shader, thanks!

There is a new driver and this one works for me: https://www.nvidia.com/Download/driverResults.aspx/167756/en-us

The main non-Quadro driver 490.89 works too. Closing.
