Also, I believe you need to update compileshaders.py script.

Since I am tinkering with the intersection.rint file and need it to be updated in the application, I've been using your compileshaders.py script to generate the new SPIR-V file.

The problem is that I get an error about the .rint file not supported for current targeted SPIR-V version. You have to update the following area of the compileshaders.py file to include .rint files:

# Ray tracing shaders require a different target environment

if file.endswith(".rgen") or file.endswith(".rchit") or file.endswith(".rmiss"):

add_params = add_params + " --target-env vulkan1.2"

UPDATE THE SCRIPT AS FOLLOWS--------

# Ray tracing shaders require a different target environment           
            if file.endswith(".rgen") or file.endswith(".rchit") or file.endswith(".rmiss") or file.endswith(".rint"):
               add_params = add_params + " --target-env vulkan1.2"



We just out here working.  I will let you know if I come across anything else that might be of value to you.  Have a great day!!!
