UXTools and ARSessionConfig breaks when HTC Vive is connected about mixedreality-uxtools-unreal HOT 3 CLOSED

I had some issues when I had multiple headsets plugged in as well. Im not sure if this is related to your issue, but when i added "-hmd=WindowsMixedRealityHMD" to the end of my application target, it fixed many of my issues.

I couldn't test this specific setup due to lack of HTC Vive availability, but i'm pretty sure this is some ambiguity on the Unreal engine side. The Steam plugin is enabled by default, so connecting a Vive will enable that XRSystem and override the WindowsMixedReality one, so interactions stop working.

The simulated hands still show up because UXT input simulation doesn't properly check the type of the active XRSystem. I've logged this issue separately. It's an inconvenience but doesn't have much of a bearing on the main problem, which is that priority of the XRSystem is pretty much hardcoded.

I'm afraid we can't do much about this on the UXTools side.

I'm closing this bug, since it's not really an issue with UXTools but rather the HMD priority in UE4. The solution suggested by @makeshiftdan is what I would recommend when dealing with multiple HMDs attached.

Also note that with the 0.12 release of UXTools the input simulation is no longer part of the WMR plugin, so it might work a bit better out of the box (untested).
