I can’t get path tracing to work. I’m using Rocky 9 (a RHEL based centOS style distro). I have latest Nvidia drivers and all the correct settings configured. I am using the latest stable UE5 Linux binaries. The path tracing option does appear in my “lit” menu but it just makes the whole scene turn black with no signs of any raytracing noise. It just looks like a raster scene with no lights on. When I re-enable “lit” mode. All the materials are now world materials.
I’ve tried the same settings/projects in Windows 10 and pathtracing works fine using Direct x RHI.
Is this as simple as a missing dependency? or is Vulkan RHI not able to support pathtracing out of the box?
I’m curious to know whether other Linux users have been able to get path tracing to work and if so does anyone know what the missing link is for me?
