Problems with SpectatorView

JasonLPJasonLP ✭
in Questions And Answers

Hi Windows Holographic Developers,

I’m currently having some trouble with Spectator View. Everything is has compiled and appears to be set up correctly, but there is a discrepancy between what I see in the SpectatorView Hololens and what I see in the compositor view, even though both are running the SharedHolograms project from the SpectatorView samples folder. In the SpectatorView hololens, I see four colored fairies bobbing up and down, while in on my local machine I see a crown-like “energy hub” instead of the four fairies. The sharing service is set up, and both my computer and the hololens have connected to it. I know this is so because when I move the hololens, the energy hub on my PC moves accordingly. The compositor is working, but I only see the “energy hub” hologram when I change its z position in the inspector.

Feels like I’m missing something simple...
Any thoughts?

Thanks,

    Ok.... finally figured this out. Once both users have joined the Default session (PC and the HoloLens) you will see the "fairies" in the HoloLens and nothing in the compositor on the PC or in the Editor (because the hub seems to fly away).

    Now, on the HoloLens mounted on the camera, move it so that the fuzzy cursor is over any robot and then do an air tap. You should then see the blue hub appear in the center. It will open up and project some kind of "hologram" sphere above it. You should now see it in both the compositor, Editor, and the HoloLens mounted on the camera!

    Note that the "fairy" you pick is the one that will float above-left of your HoloLens. You can shoot other robots above other HoloLens devices that joined the session.

    update: Looking at the output of the Sharing Service, I noticed two things

    1) Both my PC and the Hololens are 'user0'. Should they have unique user ids?
    2) After a while 'ListServer: Handshake failed with error 1' appears in the log. The 'energy hub' on the PC continues to move accordingly when I move the Hololens, but this does seem suspicious.

    My guess is that your "Sharing Stage" component on your "Sharing" prefab instance in your scene has the "Server Address" field set to "localhost". Change that to match the IP (of your PC) that you are using in the "Sharing Service IP" field of "SpectatorViewManager" in your scene. This should resolve the "Handshake failed with error 1" issue.

    It likely won't resolve the issue of the "fairies" not appearing in the compositor and in the Editor though. Not sure why that isn't working yet as I am having the same issue you are. If I find out how to fix this, I'll post the solution here.
