Hello, I am currently trying to create an application using Unreal Engine that can switch between desktop mode and VR mode. The target is PCVR using Focus3.
However, for about a month now, there has been an issue with switching between desktop mode and VR mode in applications using Unreal Engine. While it usually starts correctly in VR Viewer, the following problems occur:
Standalone:
- VR does not start
- Freezes after briefly switching to VR mode
Package (Development):
- When switching from desktop mode to VR mode and then back to desktop mode, it freezes on the VR mode screen
Package (Distribution):
- VR does not start, VBS freezes, and the PC application also freezes
This issue occurs not only in custom projects but also in the Collab template. Additionally, it happens in versions 5.1 and 5.2, and it is not an individual issue but occurs on multiple PCs with Focus3.
I remember it worked when I created another application about six months ago, and the package completed at that time still runs smoothly. However, the switching issue is now happening even in those older projects that were previously functional.
I have confirmed the following:
- OpenXR plugin (not used with Steam or Oculus)
- Runtime OpenXR is SteamVR
Has there been any disruptive change that I am unaware of? Any information, no matter how small, would be appreciated.
