Hi everyone,
I’ve been trying to build and start my Unity VR application with WMR and OpenXR but it doesn’t seem to start correctly. Under Unity playmode everything works fine and I can test my game but when I build the application for PC Standalone and try open it from my headset it starts as 2D flat screen and not as a VR app. I am using the default build settings and default openxr settings too.
Am I missing something ?
The player log file has a diagnostic output that should give you some information as to what may have gone wrong. Might be other error output in there as well with information. That’s where I would check first to see what might be up.
@joejo Thank you for your answer. I was clueless trying to change buildsettings and didn’t think about logs.
Find below my player.log file and my project settings. I think the application has a problem loading the Mixed Reality Tool Kit OpenXr plugin (in addition to unity openxr plugin) that I imported in my projet. Because I used MRTK to import OpenXr and HP reverb G2 input action map. Any clue on how to fix this ?

First thing I would suggest is to just create a new project, manually add OpenXR plugin, enable it and see if it will run correctly. That will at least narrow things down a bit to just the OpenXR support in Unity.
Just want to remove as many variables from the equation as possible.
Hello @joejo
I finaly got it to work !
I tried to do as you told me, so i created a new project and imported OpenXR and XR integration toolkit, BUILD it and it worked. The thing is with just that you don’t have the HP Reverb G2 Controller Profile. So I added the OpenXR and Input Manager with MRFT (as they tell you to do in the Microsoft documentation), BUILD it and it worked again ! So I checked what was different in my original project and the only thing is (I don’t know why) that I added the Motion Controller Model in the OpenXR project settings. I think this option only appears after you have used MRFT to import the input package. I disabled it (because I don’t need it) and now my original project works !
Awesome! Sorry that gave you such trouble.
