Unreal Engine Simulation Environment Requirements and Limitations

Simulink^® 3D Animation™ 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

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

Software	Windows	Linux
Operating system	Windows 64-bit	Debian^® 11 (recommended)
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.

The table summarizes the Unreal Engine version supported by your MATLAB^® release.

MATLAB Release	Unreal Engine Version
R2022b	4.26
R2023a–R2023b	4.27
R2024a	5.1
R2024b	5.3

Recommended Hardware Requirements

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

Hardware	Windows	Linux
Graphics card (GPU)	Virtual reality-ready	NVIDIA GeForce^® 960 GTX or higher with latest binary drivers
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

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.
