If you have Quest 3, try the room scanning once because you paid for its depth sensor. It actually works, although it is not perfect.
I heard that Meta will release the real-time depth API with better accuracy. I’ll update this feature once again when it becomes available.
Playing with Room Scanning
Gameplay video making use of Quest 3 room scan.
Take your time to get the best room scan possible. The better the room scan is, the better the shadow gets.
I once tried to get a whole scan of my home. But it turns out Q3 room scan has time limits. I think 2-3 rooms is a practical limit.
