I am building a simple app in unity using vuforia. For the first tie ever yesterday, it started giving me black screen when i press play mode and the following message in my console: "Trackable (Name of the Target Image) NO POSE -- UNKNOW"


Could anyone please point to where the problem could be. I am new to unity and I have little experience in code.


Thank you in advance.

I built upon the Sample App Model Targets to implement multiple Area Targets. Therefore I activate AreaTargets over API. The Targets are being found in the real world and augmentation is visible. Nevertheless in the Simulator the method OnTrackableStatusChanged() of the DefaultTrackableEventHandler is only called when initializing or activating the DataSet, but stays NO_POSE. Also the Area Targets & augmentation in the scene are not visible (only Simulator), but activated. Am I missing a setting for the Simulator? Do I manually have to call the OnTrackableStatusChanged() method? If yes, how?

I'm using Unity 2019.14.15f1

Vuforia Engine: 9.6.3

Thanks in advance for your help!

If you're new to Vuforia/Unity, my suggestion would be to start with our Core Sample apps, available through the Unity Asset store. It is a demo app with all features from Vuforia.

Create a new project and import the Core Samples from us.

Info on getting started: https://library.vuforia.com/articles/Training/getting-started-with-vuforia-in-unity.html

Coming back to your questions, please check if the webcam is available in the vuforia configuration file, CTRL+SHIFT+V. Under Play mode, make sure that WEBCAM is selected and the camera device has your camera model there.

Could you please confirm if it worked before?

- Vuforia/unity versions?

- what features are you testing?

Thank you.
