Thanks for answer, 

I use a simple 2D circle in order to follow a basic image target .

Im usining the image target fonction whith an AR camera. When i deploy it on my pc cam it works perferctly, but no result on hololens.

I can't  show you that behaviour because of the cam is disable when i deploy unity, but i will explain

During the deployment, axes of tracking are like inverted. When hololens detect the target, and i moove the target right , the circle moove on left.

I have this problem for the hololens sample also.

thanks.

Hello cyrildemaria,

What sort of tracking issue are you seeing? Which feature are you using? Can you share a video of the behaviour? Do you observe this behaviour in the samples?

Thanks,
