How to setup VR functionality for user to step to center

I need to add to project an initial setup screen that asks the user to step to the correct spot on the world for the user’s ax to be centered when moving. Usually, it is a circle on a dark space and some text that asks the user to go and be on the circle. I can’t find anything on it. Help, please!

hi, but HMD return coordinates from the center of your room, but why do You need this? From what You are describing it sounds like it is needed fr some sort of calibration?

In some games, when you start, it asks the user to be on a circle on the floor, and facing a specific direction. yes you have done that when you calibrate the room, in essense is the same thing, but just to fine tune it.
