I come from this thread: Cast raytraced shadows and vulkan/linux
Late, but I’ve waited for bookworm.
Now I have a clean install of Debian 12 with the repo nvidia driver (525) and the UE5.2.1 downloaded by the ue site.
I check all the parameters mentioned in this thread, you can find in the screenshots.
As stated by @focalcgi there’s a clear warning message, complaining the failing of the compilation of the material for the platform VULKAN_SM5.
Is it the problem that creates those horrible shadows?
Any idea on how to proceed?
An other note, if I click on “Path tracing debug” and I choose an option what I see it’s a black screen, same problem I suppose.
