Template Collab Viewer VR preview closes editor

Hi,

I am new to UE4 and I tested the Collab Viewer for an architecture project but I found an issue with the VR preview on the editor

I follow the documentation to play with VR in Editor

When start the VR Preview (on CollaborativeViewer_P maps), a new window appears and all work for the template but if

  • I do ALT + F4
  • Close the window
  • Click on the stop button in UE4

The VR preview stops and after a few seconds… the editor closes itself (or perhaps crash but I don’t have a crash report window)

I test the basic VR Template for games and I don’t have the problem.

I use a Rift S / UE4 24.3

Do you have a solution ?

Thank you for the help !

I’m having this problem as well. It also seems like since 4.24 the Collab Viewer doesn’t run for VR in editor… only after being packaged. Can this be fixed?

Hi, I found an solution for my issue.

I have to disable SteamVR plugins and the Editor VR Preview works.
After that, I enable SteamVR plugins and everything works as expected.
