Unreal Engine Setup

Follow these steps to set up Unreal Engine, install the required plugins, and add controller pose tracking to an object. These instructions have been tested on Unreal Engine 5.5.

2. Add a new source:

   • Click Add Source and select LiveLinkOpenVR Source.

   • Choose the necessary trackers from the list under Track Controllers.

3. Verify that four devices are listed. The two main controllers should appear as:

   • Controller_Amfitrack_Controller_Right

Set Up an Object with LiveLink Tracking

1. Locate the required Blueprint:

   • Navigate to Project > Engine > Plugins > LiveLinkXR Content > Blueprints.

   • Drag and drop BP_LiveLinkXE_DataHandler into the viewport.

2. Create a 3D object to track (e.g., a Cube).

3. Select BP_LiveLinkXE_DataHandler in the Outliner.

4. Configure the tracking:

   • Under Subject Name to Attached Actor, click the + sign to add a new entry.

   • Open Live Link and identify the controller name (e.g., Controller_Amfitrack_Controller_Left).

   • Enter the controller name in the Subject Name to Attached Actor field.

   • Use the dropdown next to the field to select the 3D object for tracking.

5. Verify the setup:

   • The 3D object’s location should update based on the AMFITRACK device’s movements.

Troubleshooting

• Plugins not appearing: Ensure you’ve installed the correct plugins and restarted Unreal Engine after enabling them.

• Devices not listed in Live Link: Verify that the AMFITRACK SteamVR driver is installed and running correctly.
