Networking is a LASR X feature that allows you to connect multiple devices together to behave like one: You can control the software from and veiw results from any device within your network. This allows for multi-directional, multi-room, multi-shooter, remote controls, and much more.
To use networking, you will log in with the same account on every device you are wanting to use. Your account will need to have that many simultaneous logins allowed, which is an upgrade that you can do through your account management page within LASR X.
From there, simply turn on the main switch under "Networking" on every device, and boom: your network is established and ready to go.
