Hello Tomas,
Yes i figured it out, and can’t help but to feel annoyed by how even the TA is making wrong assumptions here. The fact that someone has a VR headset, doesn’t translate automatically to them knowing how set it for development. And NO, it is not a simple task. I personally stopped taking this course because it doesn’t even come close to GameDev other courses standards, this was really poorly made and managed course by every mean.
Here are the steps for you to set your Quest device.:
1- You can’t turn on the Developer Mode from the headset (unlike most other devices), you need to create a developer account on Meta (using your Facebook account), then use this account to log in to the Quest app on your phone or on your PC Oculus application. Also, you will need to create an organization on your developer account.
2- Then from the app, you need to first pair the device (please use USB-C or connect it to USB3 ) to link your device. If you use Airlink, you will later have problems with Unity not finding your headset.
3- Once it is linked, you need to activate the developer mode from the “Device” tab on on the left side of the PC app.
4- The most important step is to set your device for Open XR runtime. You will find this on the Quest app > Device> settings as well. If you miss this step, you will not be able to run your app on the headset.
Best of luck.
