In this video I shared my first impressions on the XR setup on Godot 4.

Tempted to make a tutorial out of it, but the guide on the documentation covers the setup process pretty well. Also, I guess speed-running it is more fun.

I was trying to search for the "Oculus Integration" plugin (because that's needed on Unity), and was genuinely surprised by the fact that passthrough and hand-tracking features came with Godot out of the box.

Overall, very easy to setup, and I would definitely recommend it to anyone who is interested in developing VR games.
