Unity Markers - Flipped in App Simulator vs Real World?

Unity Development

In my testing, when I set up a marker in the Application Simulator and read its location and orientation. It appears to be produce a result that is 180 flip vs when I read an actual marker on device, in the physical world. I expected the result of identifying a marker to be consistent between them.

This appears to happen to two kinds of markers (tested so far):

  • APRILTAG_36h11 id 0
  • QR Code

Has anyone else noticed this behavior?

Hi @otri,

Welcome to the Magic Leap 2 Developer Forums. We are so grateful to have you here engaging with us.

It seems that I am unable to reproduce this issue on my end. May I ask which target you chose (Simulator, Device, Hybrid)?

Best,

El

Hi El,

Both Simulator and Device mode in Application Simulator behave similarly.
Only when running on device does the orientation flip.

I can't share the client's code, so I'll prep a standalone sample project that reproduces what happens.

Best,
Aaron
