Oculus Unreal Integration - v1.41 (10/09/19)

Version 1.41 of our integration for Unreal Engine 4.23 has been released!

The Oculus Integration for Unreal provides support for VR applications that target the Oculus headsets. This integration enables your applications to support stereoscopic rendering, orientation tracking, and positional tracking.

For more information, see our Unreal Engine Developer Guide.
For beginning or casual developers, we recommend the Unreal Engine binary available through Epic’s Launcher: https://www.unrealengine.com/download

Oculus Source Distribution

Note: To access the latest distribution of our Oculus Source, you must log into a subscribed GitHub account first, otherwise you will get a 404 error from the link below.
You can grab the latest version of the Oculus UE4.23 Source here: https://github.com/Oculus-VR/UnrealEngine/tree/4.23

More information about this release can be found here.

New Features

  • Enabled late-latching on Quest + Vulkan. This feature can can reduce rendering latency by up to 1 frame. To enable late latching, check the LateLatching checkbox under OculusVR plugin settings.

Integration Changes

  • Updated the Oculus Unreal Integration to 1.41.
  • Updated the Platform SDK integration to 1.40.
  • Updated the Audio SDK integration to 1.41.

Bug Fixes

  • Fixed a controller-updating race condition, which could cause controller movement hiccups if the app hit the FPS target.
  • Fixed a Dash depth compositing issue on UE 4.23.
  • Fixed a pipeline state cache bug under Multiview, which can cause memory leaks and render-thread slow down.

Known Issues

  • A significant drop in frame rate occurs when UE4 is not in focus in VR preview mode. To avoid this issue, uncheck the Use Less CPU when in Background in Edit > Editor Preferences > General (left sidebar) > Miscellaneous (left sidebar) > Performance.
  • Exclusive Mode issues: Setting the mirror window to full-screen exclusive mode will not work correctly if the monitor and HMD are connected to different GPUs.

      Are Splash Screens broken in this version?  I haven't been able to get them to work.  They weren't working for me in the last 4.22 version either -- I got a lot of red text with this error:
      LogHMD: Error: Splash ovrp_WaitToBeginFrame 677 failed (-1002)

        @"tpg.sabibo00.quest" yes, broken again in 4.23 and 4.24.0 p1. They used to work in 4.22 for me.
        Just by going: ProjectSettings/OculusVR/SplashDescs -add and element and choose an image.

            I'm using the Oculus Splash screen with the Oculus dist 4.23 with my rift and it is working .
            In project settings->Plugins-Oculus->splash Screen:

            NOW on my WIDGET (OSSSession) which open my MP level (listen) I put the logic for the Splash Screen there:

            As you can see I have included several Textures with delta rotation to have special effects AND IT WORKS.

            As of this post today, my UE4 editor frame rate has tanked with the latest oculus drivers that were installed as required. Frame rate was liquid smooth before update, now it's all jittery and very difficult to develop with this new update. Any way I can get the prior drivers back so I can continue developing without these jitters?

            My specs are in my signature. I have Nvidia's latest drivers installed. Using UE4 4.23.1

            Solutions?

                  4.24.1 + 1.44 (12.0) is out and I had this issue when generating project files (although it seems to build fine without avatars and OVRLipSync):
