The camera appearing in the floor sounds like when the game boots to the HMD but you’re viewing on desktop. It might be launching in VR if the Quest HMD is in link mode.
In VR, currently, you are intended to hit the pause button and open your wrist menu, which enables your VR pointer to click in menus and stuff.
On the Quest, hitting B should open the interaction menu once you’re inside- and if you’re using GPT or the Robot Punch api, holding Y will handle short PTT recordings.
I might have got those buttons mixed up.
I should make a video explaining some things, I think.
