I'm trying to accomplish the same thing with the Quest, so I'll +1 this. Out of curiosity, are you currently building to the device every time you want to test something or are you using the link cable?
@SharpeGame Did you ever figure this out?
btw when using Oculus Link, OVRManager.boundary.GetConfigured() still returns false. To get around this, I just dumped the values returned from OVRManager.boundary.GetGeometry(OVRBoundary.BoundaryType.PlayArea) while running non-Link and use those when testing.
Yes, I did figure it out actually! My problem was that the code I was running was trying to align it using coordinates local to the boundary instead of the boundaries global coordinates. Once I made the conversion everything *worked* as intended. If you would like I can post a breakdown of how I accomplished this or give you some pointers on your own code if you have already attempted it.
