Unity 2020.3.8 issue with MRTK 2.8.2 - deployed app show up blank

[kianng]

Describe the issue

I followed the documentation MRTK2-Unity Developer Documentation - MRTK 2 | Microsoft Docs and setup my MRTK 2.8.2 using Unity 2020.3.8. The issue is every time I deployed to device, I see a blank scene with only hand ray on, no profiler, no project scene. I even tried it on a fresh Win 11 machine, followed the documented steps and still failed. So today I tried using my MRTK 2.8.2 project on a different Unity (Unity 2021.3.5f1) and it was successful!

Feature area

What's incorrect? What's missing?

Existing doc link

(https://docs.microsoft.com/en-us/windows/mixed-reality/mrtk-unity/mrtk2/?view=mrtkunity-2022-05)

Additional context

My setup was following everything in the doc, from my VS2022 and its components to MRTK Feature Tool.

Hi @kianng, one of the potential reasons could be the Unity version you were using. Could you give it a try with the latest Unity 2020.3 version (2020.3.39)? There have been a few issues Unity has fixed since 2020.3.8. We put that version on the website a while ago but probably should update it.

Hi Max I loaded the same project with Unity 2021.3.5f1 and has no issue deploying on device. My recommendation here is to update the documentation on the site so no one else will encounter this blocker.

Thanks! Kian
