Vuforia and MRTK for Hololens 1 : ImageTarget not working

I'm creating a simple app with a menu and multiple scenes. The structure is the following :

  1. Loading (empty scene, MRTK Scene Manger, load the main scene, contains the camera)
  2. Main (4 buttons used to change scene, no camera)
  3. Cube (a scene with a cube, no camera)
  4. Scenario1 (a scene with Vuforia and ImageTarget, contains Vuforia Behaviour script)
  5. ...

The problems
I have one main issue :

When I launch the application in Unity, Vuforia use my webcam as a camera and the ImageTarget are detected really quickly. However when I deploy on the Hololens using USB method (since Vuforia isn't supported using Hololens Remoting Player), it's really hard to detect the ImageTarget. The ImageTarget got 4/5 stars when uploaded on Vuforia and these are my settings : enter image description here
In Vuforia database I also set the height of the target to 0.21m since I printed it on a A4 sheet

There you can see the scene system I use : enter image description here

For the camera, the loading scene contains the Main Camera, then in Scenario1 I have an empty object containing Vuforia Behaviour Script.

Question

Why is Vuforia having so much troubles to detect the ImageTarget when running on the Hololens ?

Solution
