vr preview mode does not work well

In Unreal Engine editor,vr preview mode does not work very well.

What headset are you using? If you launch the HTV Vive “SteamVR” or Oculus “Home” before launching Unreal Editor, you shouldn’t have a problem.

Also make sure you run the project as Administrator.

It is so annoying but unfortunately I think this is the only way to make it work. I have a shortcut to the engine on my desktop to UE4Editor.exe “C:\Program Files\Epic Games\4.13\Engine\Binaries\Win64\UE4Editor.exe”, I right click the shortcut and select Run As Administrator, and project I was working on last opens up.

You can also run the Epic Games Launcher as administrator and any project you open up with it will also run as administrator.
