I'm using Unity (2019.2.8f1) and tried the Vuforia Sample Unity for Hololens. The project run on my HoloLens and i can see the Vuforia Splash Screen and the UI but i still can't see the models when i look at the target pictures. I get this on console in Visual Studio 2019:
AR:ERROR: 2019-10-10 06:38:20: VideoBackgroundConfig with screen size of zero received, skipping config step
AR:ERROR: 2019-10-10 06:38:20: You must successfully set a mode with Device.setMode before retrieving RenderingPrimitives
Likewise, if i run the app directly on Unity and simulate it on the webcam eveything works fine.
Do you know why?
