Reach AR Setup Guide

Reach Cloud supports AR experiences using our Meta Prefab pipeline and our custom https://ar.reachcoud.org domain.

Guide

1. Begin by following the documentation on uploading Prefabs using Reach’s Cloud Engine SDK. You must upload for WebGL since this is a Web Based application. Other platforms will be ignored.

2. After successfully uploading a prefab, you’ll want to begin by constructing a link. Please follow the parameters section for details.

3. Take the final URL and create a QR code out of it. You may use the QR code itself as the tracked image by uploading it as the Meta Prefab thumbnail (but don’t include the imageurl parameter)

4. After following these steps you should have a working AR experience like the example below.
