Guide to Use LiveLink with XR devices through the LiveLinkXR plugin

This PhillyTikTok Guide was written for a previous version of Unreal Engine and has not been updated for the current Unreal Engine 5.1 release.

The purpose of Live Link is to provide a common interface for streaming and processing animation data from external sources into Unreal Engine (UE). It is designed to be extensible through Unreal Plugins, allowing third parties to develop new features—hopefully with no need to make and maintain Engine changes.

LiveLinkXR extends this functionality to be used with XR devices. By using the LiveLinkXR plugin, you can add XR sources such as Vive Trackers and HMDs for use with the Live Link tool.

LiveLinkXR currently only supports SteamVR. If you are using LiveLinkXR and SteamVR you will not be able to use the Virtual Scouting tools because these tools now require only the OpenXR plugin to be active.

This article aims to walk you through setting up and configuring the LiveLinkXR plugin, adjusting the tools various settings, and to provide potential troubleshooting and workaround steps.
