I don’t know about Linux, but Vulkan should support Ray Tracing with Lumen without Hit-Lighting in 5.4.
Full support is coming to 5.5 (Hit-Lighting and Path Tracer).

Thankyou very much for the reply.
For me raytracing with Lumen seems to work or at least look like it is doing something different in editor vs disabling it. I’ve not tested it much beyond toggling the settings.
Upcoming full support in 5.5 is welcome news indeed. I will be sure to test and feedback here when the time comes.
Thanks again for commenting, it is good to hear first hand information regarding this.
POh sorry about lating For replay :
there is no Path Tracing Until Now in any linux Distro With REgulat Vulkan
there is alot of trike but its not Working until Now on linux
raytracing Work Great With Lumun but no chance with Path Tracing
Linux Vulkan Pathtracing is now working as of the latest UE5.5 build. I’m using Fedora Linux Workstation with NVIDIA driver installed via official binaries from the nvidia website.
In order to get it working I had to offload SM5 (Target RHI from PLATFORM section of editor options) and load SM6 then restart UE.
Big thanks to the developers for fixing this. It is very much appreciated.
