Can't turn on stereo rendering

Development Rendering

1

VR Preview works fine, but

1.In standalone game EnableHMD() returns false, and console command ‘stereo on’ (and other hmd commands) can’t be recognized.

2.In ‘New Editor Window’ mode I don’t get ‘command not recognized: stereo on’ message, but it still doesn’t work.

3.And I have the same problems in the clean project.

4.[Preferences → Level Editor → Play] ‘Viewport gets HMD control’ flag affects ‘New Editor Window’ mode (even despite i can’t turn on stereo rendering) but, of course, doesn’t affect Standalone Game.

UE 4.10.2 launcher version, but the problem exists since at least 4.9.

Hello YuriNK,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Could you provide a detailed list of steps to reproduce this issue on our end?
  2. What VR device are you currently using?
  3. Could you make sure that your graphics drivers are up to date?
  4. If you are using the oculus, what runtime are you currently using?
  5. If you are not using a head set have you tried using “-emulatestereo” (example below)

-emulatestere example:

  1. It’s obviously not a common problem. Don’t know how to reproduce it. List of my steps: 1) create new project 2) Play Standalone Game or New Editor Window 3) ~, ‘stereo on’ - no result. OR 3) adding EnableHMD() node in Level Blueprint/BeginPlay(). No result, the function returns false.
    BUT everything works fine in VR Preview play mode.
  2. -4. Rift DK1, the lastest nVidia driver 361.43 for GTX980, SDK 0.8.
  3. Yes, emulatestereo works.

First pic: Play in New Editor Window. Command doesn’t work, but there is no any message.
Second pic: Play VR Preview.
Third pic: Standalone preview with -emulatestereo.

After doing a bit more digging I found an issue (UE-24264) that I believe is the cause for the issue that you are experiencing. I will provide updates with any pertinent information as it becomes available. I will also be sure to bump up the community interest for this issue. Thank you for your time and information.

Make it a great day

Noticed today stereo mode works in packaged project. May be useful.

Yes, I’m having the same issue here, although I seem to remember it working in an earlier version of the engine. I would imagine this is that the “Viewport Gets HMDControl” checkbox would enable, although it doesn’t work as expected.
