video in AR App with 1.94 possible?

Is it possible to use the Quest3 camera with the "AR Capture" and "AR Marker" plugins? If I create a program with them, when I load the APK onto the Quest, my avatar is displayed in the background performing my movements (as if it were a mirror). Why did I select "Yes" when loading the APK? The question "Allow this app to take photos and record videos of your avatar experiences?" appears. If I select "No," I don't see any background (the original scene).

Using the OpenXR template, however, the passthrough video is displayed, but if I add a plugin like "AR Capture," the program crashes on startup.

Is it possible to use AR plugin functions to display the background video on the Quest (and have OpenSpace3D receive the video information to identify the markers)?
Thanks!

Hello, unfortunately there is no way to use marker detection on meta quest. The camera stream is not accessible because of the meta restrictions. It seems that the last PicoXR SDK allow to detect and track markers on pico 4, but I didn't dig into this yet.

I understand, but apparently it recently added access to cameras through its "Passthrough Camera API," so I don't know if the video stream required to recognize markers is the same as for the Passthrough functions. These links have information about this:

You can now access the Meta Quest's Passthrough Camera: https://www.youtube.com/watch?v=1z3pcMJbnRA
See samples here: https://github.com/xrdevrob/QuestCameraKit

Official Passthrough Camera Samples: https://github.com/oculus-samples/Unity … ApiSamples
Documentation: https://developers.meta.com/horizon/doc … a-overview

It would be very interesting to also be able to use openspace3D's AR features with Quest. Thanks Arkeon for your hard work!
