[Question] ARM support with OpenXR and Unity #42

Closed ujell closed 3 years ago

ujell commented 3 years ago

Is ARM platform supported with OpenXR in Unity? Currently, when I deploy to the device I get the following exception in UnityEngine.SubsystemsModule.cpp:

Exception thrown at 0x76D4198E (ucrtbase.dll) in HoloIndustrieStadtpark.exe: 0xC0000005: Access violation reading location 0x00010000.

Everything is up-to-date and same project with same settings works with ARM64 (and in Editor). Additionally, simply adding the Azure Remote Rendering package to a new project is enough to get this exception.

The showcase app (which does not use OpenXR) works on both platforms. Am I missing a step or a setting? Tutorials recommend ARM64, but it's not explicitly stated as a prerequisites or requirement anywhere. This is relevant for us since MixedReality-WebRTC only works with ARM and we will select our tools according to this.

Thanks in advance!

Hi. Thanks for your report. We've reproduced this issue locally, and we're looking into it.

Hi! We reached out to Unity with a repro and we got confirmation from them that this issue has been addressed for the upcoming OpenXR plugin (version 1.2.9 that is). Would the cadence of a regular Unity minor version update be sufficient for you? Or are you blocked so that we should look into ways to provide you with a patch?

Best regards! Florian

Hi, thank you for checking this out!

Unity update is good enough; we are still on development phase so no need to spend your time on an already resolved issue.
