This page covers how to set up the Vicon Marker Visualizer Component in Unreal Engine. This involves adding a component to an actor and configuring the Live Link Subject Representation.

> ⚠️ **Note**  
> ⚠️ If your data has high marker counts, we recommend that you do not use the Vicon Marker Visualizer Component at run time as this can impact performance

To control the look and behavior of the visualized markers, you can use additional options.

> ℹ️ **Note**  
> ℹ️ When you're using **Marker Data**, consider the following points:
> ℹ️ 
> ℹ️ - Props and objects tracked using the **Object Tracker** method do not have marker data. This is because the tracking does not reconstruct markers.
> ℹ️ - Object tracking is enabled in Shogun Live. For more information, see [Understand object tracking in Shogun Live](https://vicon-help.atlassian.net/wiki/spaces/Shogun113/pages/84218813).
> ℹ️ - Subjects that have **Vicon Retarget** applied to them do not have marker data either and only their retarget skeleton is streamed.

Configure the Vicon Live Link Connection

1. Set up the Live Link source by following the steps outlined in [Connect to Vicon Datastream Using Live Link](https://vicon-help.atlassian.net/wiki/spaces/Unreal5Plugin18/pages/14845980/Connect+to+Vicon+Datastream).
2. After you have set up the Live Link source, select **Window** > **Virtual Production** > **Live Link**.
3. Click on the new Live Link to open the settings panel.
4. In **Data Stream Settings**, clear **Enabled** **Lightweight**.
5. In the same settings panel, in **Advanced**, select **Stream Marker Data **and optionally **Stream Unlabeled Marker Data**.
  - **Stream Marker Data**: Enables marker data on all subjects and adds a new **Labeled Marker** Live Link subject.
  - **Stream Unlabeled Marker Data**: Enables unlabeled marker data as a new **Unlabeled Marker** Live Link subject.

## Set up the Vicon Marker Visualizer Component

This section explains how to use the **Vicon Marker Visualizer Component.**

To ensure the markers align with data when they're visualized, you add the corresponding component to a static actor that does not move (this static actor is typically a **Vicon Origin** actor).

In the following instructions, the component is added to a **Vicon Origin **actor.

1. Go to **Window > Outliner** and open an **Outliner** panel.
2. In the panel, select the **Vicon Origin** actor.  
:check_mark: **Tip**: If you cannot see this actor, you may need to create a **Vicon Origin** actor. For more information, see [Set up a Vicon Origin actor](https://vicon-help.atlassian.net/wiki/spaces/Unreal5Plugin18/pages/14844368).
3. When you've selected the **Vicon Origin** actor, in the **Details** panel, click **Add ** and select **Vicon Marker Visualizer Component**.
  :check_mark: **Tip**: Search for `Vicon` when adding a component.
4. Select the new **Vicon Marker Visualizer Component** and go to the **Marker Visualization** section.
  This section contains all settings for the **Vicon Marker Visualizer Component.** For details on configuring these settings, see [Marker visualization reference](https://vicon-help.atlassian.net/wiki/spaces/Unreal5Plugin18/pages/14844520).
5. In **Subject Name**, select the subject from which to display markers.
  If you cannot see any subjects in this field, ensure marker data has been enabled in the Vicon Live Link Source settings. For more information, see [Configure the Vicon Live Link Connection](#LiveLinkSettings).
6. To see the markers in the editor outside of **Play Mode**, select **Show Marker in Editor**.

Markers are visualized in the viewport matching the **Marker Type**, **Marker Color**, and **Marker Size** settings.
