I'm trying to create a modular AR project by using Unity's LoadLevelAdditive feature.
Basically, what I'm trying to achieve, is to have a generic AR viewer with camera, which loads additional targets from a seperate level (depending on user input).
In Unity, the additional level (which only contains image targets) loads up fine, but when I build the iOS or even enable webcam behaviour in Play Mode, the additionally loaded targets don't work. It does say 'Num trackables detected: 1' in the console when holding up a target in front of the webcam.
I did a test by adding a AR Camera prefab to the additional image-targets-only scene, which works like it should. The additional level uses the same dataset as the generic one, so that shouldn't be the issue.
I'm guessing it has something to do with a somehow broken link between the AR Camera in one scene and the image targets in the other.
