Unreal Engine Simulation Environment Requirements and Limitations

Robotics System Toolbox™ provides an interface to a simulation environment that is visualized using the Unreal Engine® from Epic Games®. When simulating in this environment, keep these requirements and limitations in mind.

Software Requirements

Note

Simulating models in the 3D visualization environment requires Simulink® 3D Animation™.

The table summarizes the software requirements for Windows® and Linux® platforms.

Software

Windows

Linux

Operating system

Windows 64-bit

Debian® 11 (required)

Graphics driver

Microsoft® DirectX® — If this software is not already installed on your machine and you try to simulate in the environment, the toolbox prompts you to install it. Once you install the software, you must restart the simulation.

Vulkan®: AMD® (21.11.3+) and NVIDIA® (515.48+) (recommended)

Vulkan — If this software is not already installed on your machine and you try to simulate in the environment, the toolbox returns an error. To install the software, run these commands in the Linux terminal.

sudo apt install vulkan-tools
sudo apt install mesa-vulkan-drivers
sudo apt install nvidia-vulkan-common
To verify if the software is installed, run this command. 
vkcube
Once you install the software, you must restart the simulation.

Compiler

Microsoft Visual C++® (MSVC)

For a list of compatible Windows compilers, see Supported and Compatible Compilers - Windows.

GCC

For a list of compatible Linux compilers, see Supported and Compatible Compilers - Linux.

To customize scenes, you must install Unreal Editor and the Robotics System Toolbox Interface for Unreal Engine Projects support package. The table summarizes the software requirements for building custom Unreal Engine projects.

Software

Windows

Linux

Integrated development environment (IDE)

Visual Studio®

CompilerMicrosoft Visual C++ (MSVC)

Clang

In addition, verify that your Visual Studio, Clang and Unreal Engine project versions are supported by your MATLAB® release.

Limitations

  • Mac platforms do not support co-simulation between Simulink and the Unreal Engine.

  • Simulink Online™ does not support co-simulation between Simulink and the Unreal Engine.

  • MATLAB Online does not support sim3d objects or functions.

  • The Simulation 3D blocks do not support:

    • Code generation

    • Model reference

    • Multiple instances of the Simulation 3D Scene Configuration block

    • Multiple Unreal Engine instances in the same MATLAB session

    • Rapid accelerator mode

    • Simulink Online simulation.

  • For closed-loop simulation, all Simulation 3D blocks must be in the same subsystem.
