Overview

Unity's XR Interaction Toolkit is a Package created by Unity to allow developers to add cross platform VR and AR functionality to applications without the need for programming.

It serves the same purpose as VRTK, but it's newer, and more up to date. In some ways, it's easier to use. In others, less. This page covers all the things you need to get started with the XR Interaction Toolkit, and directions to make the interactions you are used to with VRTK.

Configure the Project Settings for Oculus

You now have everything you need to start building XR scenes in Unity. However, to get the project to work on an Oculus, you will need to set some more settings. These settings are for an Oculus Quest. For other Oculus headsets, consult the Oculus Developer site.
