I'm developing an application for HoloLens 2 in Unity. I started using Vuforia's ImageTarget, which works fine with a webcam in Unity's Play mode. Also building and deploying to the Hololens 2 succeeds. However, the image target is not recognized on the Hololens. I don't have any other issues with the application.
To set Vuforia up, I followed these guides: https://arvrjourney.com/hololens-2-marker-tracking-with-vuforia-engine-and-mrtk-fb582c8f8ac0 and https://library.vuforia.com/articles/Training/getting-started-with-vuforia-in-unity.html
I'm using the following versions:
Windows Mixed Reality 4.2.3
Also, I'm using the default HoloLens2 profile.
Are there any pitfalls why Vuforia is not working in my case?
