Give us as much detail as possible regarding the issue you're experiencing:  
I am using the [Marker Tracking Example](https://developer-docs.magicleap.cloud/docs/guides/unity-openxr/marker-understanding/unity-marker-understanding-example/) with a different Prefab but it keeps moving with the updated Aruco marker. Is there a way to Instatiate the object just once and stop having it move with the marker?

Hi @faziz  
I am not sure exactly what you are asking. The marker tracking example is supposed to lock a prefab to a marker, following the marker if it is moved. If you are trying to simple instantiate a prefab at a location once then you could update the script to only update the transform of the prefab once right after its instantiated, but this doesn't feel like the most efficient use.
