The problem To sum up, both Unity and Visual Studio 2017 builds the project, deploys the project, but once opening the app, nothing appears, not even a Unity splash screen. However making the bloom gesture on HoloLens proved that the app is "open" and closable, but that's as far as it gets. What we tried Our deployment target is a HoloLens 1 running the latest OS for said device (10.0.17763.380). We went through the provided solution here: MRTK (V2) Need to update Hololens?

I realize this question was asked elsewhere, but the answers seem to direct towards the paring process between Hololens and a PC, which is part of my problem. I made an app in Unity and exported to Visual Studio. When I try to run it on the Hololens, I get this error: Error DEP6957 : Failed to connect to device using Universal Authentication. Please verify the correct remote authentication mode is specified in the project debug settings. I understand that the first time you run, you should be prompted to pair both the PC and the device, but I never got this request, and I have no field to

Both HoloLens and daydream require their own Unity technical previews. The gvr Controller code is online but seems to speak directly to GVR C api. Any thoughts on if accessing daydream controller in Unity outside the daydream tech preview is even possible? 回答1: It is very possible to access the daydream controller without
