Unreal Engine Simulation Environment Requirements and Limitations

R2026b

Vehicle Dynamics Blockset™ 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® 13 (required)
Graphics driver	NVIDIA® latest driver	NVIDIA (535.86+) driver
Rendering hardware interface (RHI)	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® — 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 nvidia-vulkan-common To verify if the software is installed, run this command. vkcube Once you install the software, you must restart the simulation.

Recommended Hardware Requirements

The table summarizes the recommended hardware requirements for Windows and Linux platforms.

Hardware	Windows	Linux
Graphics card (GPU)	NVIDIA GeForce RTX® 2080	NVIDIA GeForce RTX 2080
Video memory (RAM)	8 GB	8 GB
Processor (CPU)	2.5 GHz or faster	2.5 GHz or faster
Processor memory (RAM)	32 GB	32 GB

Unreal Editor Development Requirements

To customize scenes, you must install Unreal^® Editor and the Vehicle Dynamics Blockset 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®	Visual Studio Code
Compiler	Microsoft Visual C++® (MSVC)	Clang

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

MATLAB Release	Unreal Engine Version	Visual Studio Version	Clang Version
R2018a–R2019b	4.19	2017	Not applicable
R2020a–R2021a	4.23	2019	Not applicable
R2021b	4.25	2019	Not applicable
R2022a–R2022b	4.26	2019	Not applicable
R2023a–R2023b	4.27	2019	Not applicable
R2024a	5.1	2022	13.0.1
R2024b–R2025b	5.3	2022 v17.4 or later (17.6 recommended)	16.0.6
R2026a–R2026b	5.4	2022 v17.4 or later (17.6 recommended)	16.0.6

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

  • Multiple instances of the same actor tag. To refer to the same scene actor when you use the 3D block pairs, such as Simulation 3D Actor Transform Get and Simulation 3D Actor Transform Set, specify the same Tag for actor in 3D scene, Actortag parameter.

  • Simulink Online simulation.

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