Hi,

I need a working marker tracker. First I tried Vuforia, it made Magic Leap graphics driver crash all the time. So I left it, and tried using Magic Leap marker tracker, but it makes glasses reboots itself in about 10 minutes: I don't know why. My application is working standalone smoothly if there is no marker trackers in the project.

So at the end, I decided to develop my own marker tracker. I just copied the source code given in developer portal with title "World Camera - Pixel Sensor API Example" as is, I put it into an empty scene with ML-Rig, 2 boxes, I connected boxes to script. It worked and I see world center camera streams. But the application only works for 35-37 seconds. It stops exactly in 35-37 seconds. I don't understand why, there is no timer in the code. What may be the problem with the sample?

Hey @cagatay ,

Sorry you're running into this issue!

Are you able to reproduce this behavior in the official Magic Leap Examples project?

You can find out how to access and install the example app here

I cannot make official Magic Leap Examples project work in my computer. Unity editors (both 2022 and 2023 editors) crash after several seconds when I open Magic Leap Examples (never this happens with any other projects so far). I don't know why. So I just look at their source code.

I gave up using camera for now. But I realized that perception snapshots was disabled. May be this was the problem.

Unfortunately we will not be able to help if we are unable to reproduce the issue. Could you make sure that the Unity Editor Version matches the Editor Version for the Magic Leap Examples? If you find your Editor crashing, you may need to reach out on the Unity Forums.

Additionally, please make sure your Magic Leap 2 is up to date and that you are using the latest Unity Examples Project that can be downloaded from the Magic Leap Hub 3. Please try using the un modified version of the Magic Leap Examples (do not include additional packages such as Vuforia).
