Unity Engine

Hello,

No certain if the cause is from unity or microsoft plugin but i cannot make the Hp Reverb G2 controler work with openXR.

I always get this error message :

Could not create a device for 'HP HP Reverb G2 Controller (OpenXR) (XRInputV1)' (exception: System.InvalidOperationException: Cannot find parent 'devicepose' of control 'devicepose/istracked' in layout 'XRInputV1::HP::HPReverbG2ControllerOpenXR'

Is there some Hp Reverb G2 dev here?

There is a new version of the mixed reality openxr plugin (0.1.4). Give that a try and see if that fixes your issue.

Hello @yl-msft ,

I’m also using Hp Reverb G2. Controllers G2 are not recognized in Unity (G1 work fine).
no issue with G2 headset.

Unity version 2021.2.7
openXR plugin 1.3.1

I do not use Mixed Reality functionality. My projet is only VR and with G1 controllers I have no issue.

Following the reading of this thread, I try to install Mixed Reality OpenXR Plugin 1.2.1 thanks to the Mixed Reality Feature Tool (not easy to find by the way).

I can see that I have now more openXR Feature Groups.

My question are simple, as I’m not doing Mixed Reality, do I really need to install Mixed Reality OpenXR Plugin in order to make my G2 controllers recognized.
And what are the minimum feature do I need to check to use the G2 controllers (in screenshot).

I use Microsoft Motion Controller Profile as Interaction profile in Unity OpenXR Settings.

Thanks you

If you have the microsoft packages installed which it appears you do then there should be a G2 Reverb interaction profile that you can add with the plus button.
