I am considering porting Figmin XR to the ML2 and I have to decide what runtime to use... You see it already runs with OpenXR on Hololens 2 so I was thinking perhaps that's the easier path to take.
But I don't really know where to begin, I was hoping to find a sample project or instructions to set up one.
I would be interested in a project that shows the hand tracking points for example, since our app runs great with that. But any project would be helpful.
Right now, OpenXR has initial support, but only for Native (C++) development. Our documentation for this is currently here.
We also support MRTK 2, with support for 3 coming in the future. Our documentation for this is here.
Regarding development with OpenXR in (presumably) Unity, it's essentially just a checkbox as far as I know for Hololens 2? It doesn't directly affect the way your application is developed? We don't currently offer OpenXR support in Unity, but it is coming.
