Install Support Package for Customizing Scenes

To customize scenes in your installation of the Unreal® Editor and simulate within these scenes in Simulink®, you must first install the Automated Driving Toolbox Interface for Unreal Engine Projects.


These installation instructions apply to R2024a. If you are using a previous release, see the documentation for Other Releases.

Verify Software and Hardware Requirements

Before installing the support package, make sure that your environment meets the minimum software and hardware requirements described in Unreal Engine Simulation Environment Requirements and Limitations.

Install Support Package

To install the Automated Driving Toolbox™ Interface for Unreal Engine® Projects support package, follow these steps:

  1. On the MATLAB® Home tab, in the Environment section, select Add-Ons > Get Add-Ons.

    Add-Ons menu with Get Add-Ons selected

  2. In the Add-On Explorer window, search for the Automated Driving Toolbox Interface for Unreal Engine Projects support package. Click Install.


    You must have write permission for the installation folder.

Set Up Scene Customization Using Support Package

The Automated Driving Toolbox Interface for Unreal Engine Projects support package includes these components:


  • AutoVrtlEnv folder — An Unreal Engine project folder containing the AutoVrtlEnv.uproject file and corresponding supporting files. This project contains editable versions of the prebuilt scenes that you can select from the Scene name parameter of the Simulation 3D Scene Configuration block. You must open the .uproject file from Simulink.

  • MathWorkSimulation — A plugin that establishes the connection between Simulink and the Unreal Editor. It is required for co-simulation.

  • MathWorksAutomotiveContent — A plugin that contains the elements of automotive objects that can be modified using Unreal Editor. It is required for co-simulation.

  • RoadRunnerMaterials — A plugin that contains the features of objects and base materials used in roadrunner scenes.

RoadRunner Project

RoadRunnerProject folder — A folder containing prebuilt scenes which you can directly edit using the RoadRunner scene editing software. This folder contains these subfolders:

    • Scenes — A folder containing the scene files for all prebuilt scenes.

    • Assets — A folder containing assets used to build the prebuilt scenes.

To set up scene customization, you must copy the AutoVrtlEnv project and MathWorksSimulation plugin folder onto your local machine.

After you install and set up the support package, you can begin customizing scenes. If you want to use a project developed using a prior release of the Automated Driving Toolbox Interface for Unreal Engine Projects support package, you must migrate the project to make it compatible with the currently supported Unreal Editor version. See Migrate Projects Developed Using Prior Support Packages. Otherwise, see Customize Scenes Using Simulink and Unreal Editor.

Copy AutoVrtlEnv Project, MathWorksSimulation and MathWorksAutomotiveContent Plugins to Local Folder

To copy all the support package components to a folder on your local machine and configure your environment so that you can customize scenes, use the copyExampleSim3dProject function. For example, this code copies the project files to C:\project.

localFolder = "C:\project"
The plugin files are copied to the default location, c:\Program Files\Epic Games\UE_5.1\Plugins\Marketplace\Mathworks. If you install Unreal Engine at a different location, specify the PluginDestination argument.

(Optional) Copy RoadRunnerProject Project Folder to Local Folder

To edit the prebuilt scenes directly using RoadRunner, copy the RoadRunnerProject project onto your local machine.

  1. Specify the path to the support package folder that contains the projects. Also specify a local folder destination to copy the projects. This code uses the support package path and local folder path from previous section.

    rrProjectSupportPackageFolder = fullfile( ...
        matlabshared.supportpkg.getSupportPackageRoot, ...
        "toolbox","shared","sim3dprojects","spkg","roadrunner", ...
    rrProjectLocalFolder = fullfile(localFolder,"roadrunner/RoadRunnerProject");
  2. Copy the RoadRunnerProject project from the support package folder to the local destination folder.

    if ~exist(rrProjectLocalFolder,"dir")

    All the prebuilt scenes and the assets are now located in the specified local folder.
