Choose HTC Focus 3 (or HTC Vive if you are using a tethered headset such as the Vive-Pro).

## Set the world pivot

The system automatically maps the coordinate system of every quest to a common coordinate system.

This enables a shared experience where multiple players share the same world.

In order for the players to experience the same place, every object that the player can interact with needs to be mapped as well.

Create a new Game Object and add the "World Anchor Constraint" component.

Place all game objects that the player interacts with as child objects of this new object.
