In play mode in VR with Vive, screen shows headset previews, headset shows non-stereoscopic image. How to fix this?

Earlier today everything was working great, and then suddenly this issue started.

When I press Play VR Preview in Unreal Editor, I get three windows up on my screen, two of them show “Game Preview Client” which I expect to be shown in the headset, and the Vive headset shows is a single non-stereoscopic image frame stretched across both eyes.

The Vive is in “Direct Mode” and running the latest firmware, and I have the latest Nvidia drivers.This is possibly a project setting or something I changed unwittingly.

What did I do that might have caused this? And how can I fix it? I’ve tried rebooting my machine and Vive multiple times. All the Vive apps work normally. Thanks!

The issue was I had multiplayer set to 3 users. By changing the multiplayer users back to 1 it fixed.

Hi, phongmedia , what are the steps of changing the multiplayer user to 1, I’m not able to fix the problem.
