Using VR with AR at the same time

[exowanderer]

In your video, you showed the coca cola can inside the VR goggles + AR, implemented through "Vuforia Virtual Reality SDK". I followed all of your same button clicks as in the video:

but when I deployed the app to my android phone, either (1) nothing shows up [all black] or (2) only one camera appears; i.e. 'a normal AR game'.

Do you have your full .unitypackage [with AR/VR enabled] available on your github?

I am trying to create an AR/VR app that will display historic art (in it's real size) on the wall of my classroom. I want my students to experience the full scale of a gallery of art while walking around our class room wearing VR googles with my cell phone. Obviously they'll have to take turns.

Thank you in advance.
