I have the very string suspicion that my shader is never executed in the first place since it takes 0ms to complete also with 500.000 rays cast, but i cannot tell why, it compiles its bound to the sbt the offset seems correct
#Raycasting - rays dont get recorded

Can you post your ray tracing setup code? Might be caused by a bad/wrong flag combination, but hard to tell without actual code.
If in doubt, run your app through a graphics debugger with RT support

GPU -Assisted Validation also helps.

I will cleanup my code,make it readable again and then post it :) while trying to find the error i butchered it a bit
gloomy oriole
Ok cleanup took longer than expected this is the new log
And this is my code, external functions for buffer allocation for the resource manager should work properly i used them successfully for graphics pipeline buffer creation and compute buffer creation in the same framework
Would greatly appreciate assistance on this i feel like i really tried everything at this point :/

GPU -Assisted Validation also helps.
You just mean vulkan validation layers? i already have them on they also fired while setting this up until i reached the point where i am at now. They dont throw me any warnings or errors but the rays dont shoot

If in doubt, run your app through a graphics debugger with RT support
Ill try that next do you have any specific recommendations for me that i could use?

There aren't that many choices. If you're on nvidia, use nsight, if you're on amd, use rgp.

👍 thx
I also have some progress hehe at least there is something in there now before it was just zeros
the shader im using:

yes.... GPU Assisted Validation on the Vulkan Configurator app. It points out stuff not working correctly on the GPU that the core validation cannot catch.

👍 perfect thx ill take a look

nsight doesnt seem to work with my application :/ it crashes
i can launch the gpu profiler but only if i keep the editor rendering enabled then its hard to track the raytracing calls though since they only happen once
