Ray Tracing Causes Crash On Linux

Hello @nsalberg ,
You could try disabling Ray Tracing from the console with the following command:

r.RayTracing 0

If that does not solve the issue, I would also recommend checking the CineCameraSceneCaptureComponent. In the Details panel, under Scene Capture:

  • Disable Capture Every Frame
  • Under Show Flags, then Lighting Components, disable Dynamic Shadows

After that, instead of capturing automatically every frame, you could create a Set Timer by Event (I’m also leaving below how many seconds equal certain FPS values, in case it helps you test which interval works best) and handle the captures manually. This helps prevent all cameras from rendering at the same time, which may reduce the load and possible crashes.


I also found this post discussing crashes related to VulkanRHI, and it includes some possible solutions that might help you as well.

Hope it helps!
