Unreal Engine Issues

TM-15272

Twinmotion freezes after starting in VR mode with the HTC Vive Pro 2 headset.

Twinmotion freezes after starting in VR mode with the HTC Vive Pro 2 headset.

Developer Notes

There are known issues when using Vive headsets that require the Vive Console software, such as the Vive Cosmos, Vive Pro 2, Vive Focus, and Vive XR Elite. Older Vive headset models that rely on SteamVR (Vive and Vive Pro) should work properly. We are currently waiting for a fix from the hardware vendor.
Steps to Reproduce

Repro:

  1. Run TM (UE5.4 builds)
  2. In default scene -> Run VR mode
  3. Observe view in VR
  4. Try to close TM

Result: TM freezes when you enter VR mode in UE5.4 builds. In VR view, you can see that Twinmotion is loading and then it disappears, and you are located in Vive space. See attached screenshot when clicking on VR mode (TM freezes on this view - had to force quit it).
Log attached.

VR headset: HTC Vive Pro 2
