----------- EDIT ---------------

I was able to get it to work by disabling OpenXR and enabling Windows Mixed Reality plugin.

This will be a temporary fix but, I would prefer not to use a plugin that is depricated.

When I went back to OpenXR the spatial mapping continued throwing the exception listed below.

Edit ----------- Okay I realized the spatial mapping is continuously restarting but keeps throwing this error with mirage.dll

XR-Plugin Management OpenXR Settings I installed Windows Mixed Reality to see if it would help, but it was not working before I installed the legacy plugin.

I have setup a unity project with MRTK 2 for the HoloLens 2. I am using Unity 2020.3.25 I am using Visual Studio 2019 16.9.6 I used Microsoft Mixed Reality Feature Tools and installed the following:

  1. Mixed Reality Toolkit Foundation 2.7.3
  2. Mixed Reality Toolkit Stanard Assets 2.7.3
  3. Mixed Reality Toolkit Extensions 2.73
  4. Mixed Reality OpenXR plugin 1.2.1

I have ran the toolkit configuration and have no errors or warnings and am currently using OpenXR My Build Settings

I can compile in Unity no errors, I open the deployment solution in Visual Studio 2019 and can compile without any errors.

I can deploy to the HoloLens without any errors.
However, once the app starts running on the HoloLens 2, I start getting runtime exceptions and the spatial mapping does not appear.

I have updated my HoloLens 2, so it should be up-to-date.
Input, hand gestures seem to work fine. I just do not have an spatial mapping capabilities. I am using the default profiles recommended in the tutorials. I have allowed all permissions on the HoloLens for my application just to make sure it wasn't being blocked.

It is really important I get this platform up and running with spatial mapping, any help would be greatly appreciated. I have written no code, I just have a cube and a sphere in the scene, I am trying to see the visualized spatial mapping.

Thank you in advance. BT

  • Could you provide more information about the OpenXR config in the XR Plugin Management? And please double-check the WebCam & SpatialPerceprtion capabilities have been checked in the Publishing Setting from Unity. – Hernando - MSFT Jan 06 '22 at 07:54
  • Sure, web-cam and spatial perception are both checked in Unity and in visual studio. – Brad Towle Jan 06 '22 at 14:43
  • XR PLug-in Management OpenXR checked Microsoft HoloLens feature group checked Holographic Remoting remote app feature group not-checked OpenXR sub-menu Holographic Remoting Remote app not checked Microsoft HoloLens checked Features: Hand tracking -checked Holographic Remoting remote app - not checked Mixed Reality Features - Checked but greyed out, not sure why Motion Controller Model - Checked Runtime Debugger - not checked. Render Mode - Single Pass Instanced Depth Submission Mode - Depth 16 Bit – Brad Towle Jan 06 '22 at 14:46
  • Sorry, the formatting was bad, I added screen shots to the initial question. – Brad Towle Jan 06 '22 at 14:53
  • What is the version number of your Unity's OpenXR plugin? Mixed Reality OpenXR plugin 1.2.1 depends on version 1.3.1 of Unity's OpenXR plugin, so could you check it out? – Hernando - MSFT Jan 07 '22 at 09:28
  • That was a good idea. I did not realize there were technically two plugins. Unfortunately, I have Mixed Reality OpenXR 1.2.1 and OpenXR Plugin 1.3.1...so that isn't the problem. Thanks for letting me know though. – Brad Towle Jan 11 '22 at 14:33
  • Could you open a support ticket through this link: http://aka.ms/hololenssupport so that we can provide you with a deeper diagnosis? – Hernando - MSFT Jan 13 '22 at 07:27
  • Okay. Thank you. – Brad Towle Jan 31 '22 at 19:30
  • was the issue solved? i face the same problem using MRTK 2.8 @Hernando-MSFT or Brad? – Hannah Stark Jul 04 '22 at 11:25
