This tutorial will guide you through creating a SteamVR overlay application in Unity using the OpenVR API. Overlay applications are suitable for various utilities since they can be launched simultaneously with VR games.

Sample Application

We will create a simple watch overlay application. The watch is hidden by default, and a controller button will display it for a few seconds. (Click to play GIF animation)

We will also create a dashboard to switch which hand to display the watch.

Prerequisites

Everything in this tutorial is confirmed to work in the following environment.

• SteamVR beta 2.5.2
• Unity 2022.3.21
• SteamVR Unity Plugin v2.8.0 (OpenVR v2.0.10 included)
• Meta Quest 3 (firmware v63)
• Virtual Desktop v1.30.5 to connect HMD to SteamVR
• Windows 11

It is fine to use another connection method if it can connect to SteamVR.
