Stream Vicon Tracker object into Unreal Engine 4

Before you begin

Before you begin, ensure the following preconditions are met:

• Tracker is installed on a capture PC.
• Unreal Engine is installed on a game-ready PC.
• The latest Unreal Engine plugin is installed on the game-ready PC.
• The two PCs are connected via a network.
• Vicon LiveLink Datastream Plugin is installed (see Install and set up the LiveLink plugin).
• UE4 project is open.

Complete the following steps in the order shown.

Create the object in Tracker

1. Create an object from the reconstructions by pausing playback and using Alt+drag to select them.

   

2. To prevent naming hierarchy issues later, set the name of the object to "root".

   This sets the root bone to root and enables any default FBX to be used.

Set up Live Link

To set up Live Link, use one of the methods described in Install and set up the LiveLink plugin.

Set up the prop or object

Your method for setting up a prop depends on the version of Unreal Engine that you're using:

• Unreal Engine 4.26 and earlier: For setup steps for a skeletal mesh, see Create Animation Blueprint (Prop/Object).
• Unreal Engine 4.27 and later:For setup steps for a skeletal mesh, see Set up Prop/Object using Transform Role.

Check the animation at runtime

The animation is now streaming onto the character as seen in the preview window. The next step is to check the animation is still streaming at runtime.

1. On the tool bar at the top, click Play and observe the animation data streaming onto the character.

Package the project

1. Follow the instructions in Packaging a project.
2. Launch the executable.
