Greetings,
I’m beginning development on a Unity project that aims to let multiple users interact with the same object—either remotely or while sharing the same physical space.
I’d greatly appreciate it if anyone could point me in the right direction, especially if there are existing tools, frameworks, or resources that could help me get started.
To be honest, I’m slightly concerned about the deprecated features and I hope none of them were essential for this kind of functionality.
The Magic Leap 2 runs an Android based operating system, which means that we do not restrict or require custom solutions for our platform. Instead you can use solutions that are already availed from 3rd parties like Unity Netcode, Photon, Mirror, etc. Unfortunately, the implementation of these 3rd party solutions is not device specific and falls outside of what we can provide help with on our developer forum. But the general question is still a good community discussion 
If you run into issues implementing any of the 3rd party solutions, I recommend reaching out on the Unity’s Official Discussion Forum.
