What I have in my setup for a project under an NDA are the Spectator View Compositor, the HoloToolkit Build Window, and all of the components of the Mixed Reality Toolkit for the Sharing Service backend program. It's been a tough setup, because of dependencies and different compiler errors upon building the DLLs.
I've added the SpectatorViewManager prefab and the Sharing prefabs from the respective toolkits. For some reason, one of the HoloLens headsets we have doesn't seem to respond to the request Unity makes to install the app even if this laptop and these two headsets are on the same network. Thus, that HoloLens has the app loaded up through USB instead (on localhost, that is).
I'm wondering what else I'm missing in order to enable Spectator View on the app itself. One component I'm missing is the anchors, but even then I feel there's more setup I must do before the Available Sessions interface that's loaded by the Spectator View Manager disappears upon running the app for the first time. I feel like the actual documentation seems to be quite hard to follow, rather than a straightforward setup as I was hoping for.
For now, there won't be a rig setup; it's only going to come after.
What am I missing?
