A demo project using the Nreal Air as a XR headset for unity on windows
Clone / Download this repo and import into unity hub
Once you open the project in unity navigate to Assets/Scenes
Open the "AirPoseDemo" Scene and press play at the top.
If your glasses are connected you should be able to move them around and see cubes in the editors Game window.
Depending on how many displays you have and what display your Nreal Air shows up as varies from user to user. I havent looked much into setting up a menu so its hard set.
To change this goto the main camera under XRRig->Camera Offset->Main Camera in the tree.
Set "Target Display" to the correct number for your glasses.
You should now be able to build/play with the game opening on the glasses.
