Multiple target tracking does not work.

I did changed the Max Simultaneous Tracked Image to 4 in AR camera configuration.
I have only 4 targets in scene in which I want to tracked them at the same time,
but when I build to andriod, the app can only tracked one target.

Vuforia version 8.1.10
Unity version 2018.3.7

 

Hello,

I believe your use of Vuforia game objects is incorrect. Here is the hierarchy from our Core samples, which demonstrate multiple target tracking.



These samples are available for free on the Unity Asset Store and provide best practice examples for Vuforia's use with Unity.

Thanks,

Thanks for the reply. I set up everything the same with vuforia sample project but the tracking still did not work. So, I created a new project and imported everything to the vuforia sample scene and it's working now.
The new problem is the lighting issue.
I can see models fine in editor but they got real dark in the app.
If I move my camera near the model, they will lighten up.
Why is this weird behaviour happening?
The directional light is not parent to anything and the world center mode is set to the first object.
