The question for mode of 2d and 3d project in unity project based ons hololens.

Unity Engine

I am developing a hololens application by unity editor 2019.1.0f2 through windows platform, and there are some questions about the mode of 2d and 3d.
At first, I created a 3d project and the application is a 3D mode which could show the holograms beyond a window. After I import some packages and delete them, the application becomes a window in front of me.
I have checked the mode of 2d or 3d in the project settings, it is still 3d mode. But actually, the application is in a plane window.
how could I switch the application to behave beyond the window?
thousand thanks

In the player settings, under XR settings you need to enable “Virtual Reality Supported” and add “Windows Mixed Reality” as the first item. Also, make sure to sure D3D build type.

Hi. My apps also launch on 2D. I checked those settings. Any suggestions?
It works fine in Holographic remote.

Unity 2019.1.2f1
3D Templete
HoloLens RS5

Thanks.

Do either of you have a small repro project that we can look at to see what is up?

New project or MRTKv2 cause it after configure recommended settings.
Honestly, I want the Unity 2019 project working on HoloLens…

Does this happen WITHOUT MRTKv2? If so then that is an issue we can help with. If not then that is probably an issue with the MRTK and should be reported to the Git site for that package: GitHub - microsoft/MixedRealityToolkit-Unity: This repository is for the legacy Mixed Reality Toolkit (MRTK) v2. For the latest version of the MRTK please visit https://github.com/MixedRealityToolkit/MixedRealityToolkit-Unity

I have a question also, do you have Holographic Remoting Support enabled under the XR Settings? If so, we have at least one bug around some behavior that affect the way the app launches which aligns to what you’re reporting. I would love to see a repro project if you can provide one to us. Much appreciated!

yes. New empty project also happen.

Hello. I solved the problem that launch apps on 2D.
I did these things.
[1] Update Windows SDK to 10.0.18362.0 (I used Insider Preview before)
[2] In Player Settings on Unity, XR Settings > Uncheck WSA Holographoc Remoting Suported (You must!)
It works on Unity 2019.1.2f1
HoloLens RS5
Visual Studio 2017

Thank you.

Ah yes, that is a potential behavior if the WSA Remoting check box is enabled. I have a conversation scheduled to review the design of this feature because I find it incredibly confusing that you launch into 2D flat when that checkbox is on.
