Hi,
It's been a while since the last reply but is this solved yet? I did manage to connect the Focus 3 to Direct Preview using Wi-Fi and I'm able to see the headset movement in the editor, but sadly I can only watch a small frame of the unity scene in the headset, everything else is black.
Curiously, I made a recording of the headset in order to show what I'm talking about, but after checking the recording in the computer, it looks fine there.
Just fyi, I'm working with Unity 2021.3.2f1 and Wave XR / Wave Essence plugins version 4.4.0-r.8
Thanks!
