Using Vuforia on Nreal Glasses

Unity Editor
October 22, 2022 - 7:44am #1


I am working on an AR project in Unity that requires real time object detection and tracking to work on the Nreal Light glasses. Vuforia seems to have the Model Targets feature for this purpose; however, I wanted to clarify if Vuforia supports the Nreal glasses.

Is there a way to use Vuforia with Nreal Light since it is also an android device and Vuforia has platform support for android devices. Could you please guide me on this matter? Awaiting your quick response. Thanks.

Object not tracking on Magic Leap One

Unity Editor
October 21, 2022 - 2:30pm #1

I am currently running Unity 2020.3, Vuforia 10.9 to track model targets. The virtual object does not overlay the physical object and thus is not tracking properly even though I have followed the step by step tutorial on the developer website. Some people have claimed that using the vuforia magic leap sample helped them out when they swapped the imported assets with their own, unfortunately I do not have the 10.9 Magic Leap Unity sample as it is not listed on the website. 


any help is appreciated. Thank you.

• Unity 2022.2.0b8

• Magic Leap SDK 0.53.3

• Vuforia Engine AR 10.10.2

• HMD OS; Build: B3E.220721.07-R.027_user (Internal device) - SDK Version 29

From our test the MagicLeap 2 Integration is not doing anything. It works fine in the editor through a webcam, and fine on HoloLens, but can't get any image recognition to work on the ML2 HMD.

What we've tried;

• The log doesn't give any errors or warnings - just that no pose was found;

No Guide View visible on the HoloLens

September 21, 2022 - 7:03am #1

Hello, everyone,

I have integrated Vuforia into Unity.

Then the example Model Target the rover. In Unity I see the Guide View 2D and 3D.

When I deploy the project to the HoloLens, I don't see it and no object is recognized either.

I really only integrated Vuforia according to the instructions using the import package and then activated the model target with the ARCamera and the Guide View. (

Integrating Vuforia With Open CV for unity On the Magic Leap One Device

Unity Editor
June 27, 2022 - 6:39am #1


I am trying to develop an application that does real time object detection on Magic Leap One Device. I have tested the Vuforia's Model Targets on the device and was able to detect some objects with the help of the guide views. However, I am interested in integrating custom models trained using OpenCV with Vuforia in Unity. Is there any way to implement this?

Your quick response is highly appreciated.

Hi there! Has someone else tried to build a 32bit ARM Unity app for the HoloLens 2 with the Vuforia Library included? If I compile my project as an ARM64 UWP application, Vuforia is working fine. If I compile as an ARM (32 bit) UWP application however, I get the following error message:

DllNotFoundException: Unable to load DLL 'VuforiaEngine.dll': The specified module could not be found.
