Hi, In my app I have one scene with all the markers and one ARCamera.
The markers uses a custom loadTrackableEventHandler and OnTrackingFound() will load a different scene speficic for each marker.
If I have a camera for each scene all works fine, but on certain devices it loads really slow due to the fact that there is an ARCamera for each scene.
In order to have one camera only I'm trying to use the keepCameraAlive but all the markers are disabled. Its really weird...
If I remove the keepcameraalive all works fine.
Using Vuforia 4.0.105 on unity 4.6.4p3 (but happens on p2 and p1 as well).
