[BUG] UE4 crashes when using SteamVR, Vulkan error

Open tapla opened this issue 5 years ago • 5 comments

I'm trying to run SteamVr with UE4 but Vulkan seems to crash every single time beside the error below it also gives the warning lavapipe is not a conformant vulkan implementation I'm not sure what that means and what to do about it. It seems to be more of a vulkan issue caused by steam. without steamvr running ue4 starts fine. i can open it with opengl though perfomance is pretty bad. maybe somebody knows how to fix this or at least what causes it thanks

Hi there, I'd just like to add that I've been having a similar problem with UE4 and VR-mode. Running Pop!_OS (20.10, GTX 1070 @ Nvidia 455.28) and trying out the Carla simulator in VR-preview crashes every time. I have to resort to using OpenGL backend but its much worse in quality. Typically the error looked something like: Error: Ensure condition failed: Layout == VK_IMAGE_LAYOUT_SHARED_PRESENT_KHR || Layout == VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_STENCIL_ATTACHMENT_OPTIMAL || Layout == VK_IMAGE_LAYOUT_DEPTH_ATTACHMENT_STENCIL_READ_ONLY_OPTIMAL || Layout == VK_IMAGE_LAYOUT_DEPTH_STENCIL_READ_ONLY_OPTIMAL || Layout == VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL || Layout == VK_IMAGE_LAYOUT_GENERAL [File:Runtime/VulkanRHI/Private/VulkanDescriptorSets.h] [Line: 1103]

I can also try again a few more times and get more logs if interested. Happy to help!

I am also seeing the exact same issue, any suggestions? Cannot start UE4Editor or my project Editor with SteamVR running.

  • Ubuntu 20.04.2 - Linux 5.11.0-40-generic
  • NVIDIA Titan RTX - 495.44 / CUDA 11.5
  • Engine Version: 4.27.1

Some progress. With a hack to Engine/Source/Runtime/VulkanRHI::VulkanDevice to load specific VK Extensions, instead of what UE4 is determining.... I am able to load UE4 Editor w/ the SteamVR plugin enabled while running SteamVR.

Unfortunetly...while in the editor, if i launch VR preview... UE4 still crashes. So i do not have a solution yet.

More details in my ue4 forums post link above

I have resolved the issue for my target system and project. It required bypassing the UE4 methods for getting the required device extensions, and passing it a static list of VK Extensions i specified.

Specifically:

  • VK_KHR_get_physical_device_properties2
  • VK_KHR_surface
  • VK_KHR_xcb_surface
  • VK_KHR_display
  • VK_EXT_direct_mode_display
  • VK_EXT_acquire_xlib_display
  • VK_EXT_display_surface_counter
  • VK_KHR_external_memory_capabilities
  • VK_KHR_external_semaphore_capabilities
  • VK_KHR_get_physical_device_properties2
  • VK_KHR_swapchain
  • VK_KHR_maintenance1
  • VK_KHR_dedicated_allocation
  • VK_KHR_get_memory_requirements2
  • VK_KHR_external_memory
  • VK_KHR_external_semaphore
  • VK_EXT_display_control
  • VK_KHR_external_memory_fd
  • VK_KHR_external_semaphore_fd
  • VK_EXT_global_priority
