Compatibility
UXF should be fully compatible with all major build targets, including PC, Oculus Quest, WebGL, WebXR, Android & iOS. However, data output is not yet implemented in all cases.
It is possible to implement your own data handler to handle data how you wish. Even though Android, Quest, iOS etc are in-theory compatible with UXF, there is no suitible data handler at this time, meaning no data collection. There are plans to create a data handler which will work on Oculus Quest & Mobile platforms.
For best support use Unity Long Term Support releases (LTS). UXF supports Unity versions 2018 LTS and up.
UXF works with any Windows based Unity project, that means it is not currently compatible with Android/iOS, or other platforms like the Oculus Quest (unless via Oculus Link). There are no restrictions beyond the Windows requirement, it works with Oculus Rift, HTC Vive, Oculus Quest (via Oculus Link) or any headset compatible with Unity on Windows. It also works without any headset at all (e.g. keyboard/mouse based tasks).
For best support use Unity Long Term Support releases (LTS). Currently recommended is Unity 2019 LTS but 2017 and 2018 also work.
