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®. This visualization engine comes installed with the toolbox. When simulating in this environment, keep these requirements and limitations in mind.

Software Requirements

The table summarizes the software requirements for Windows®.



Operating system

Windows 64-bit

Integrated development environment (IDE)

Visual Studio®

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.

Recommended Hardware Requirements

The table summarizes the recommended hardware requirements for Windows.



Graphics card (GPU)

Virtual reality-ready
Video memory (RAM)8 GB

Processor (CPU)

2.60 GHz

Processor memory (RAM)

32 GB


The 3D visualization engine is not supported on Mac and Linux.

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.

You cannot create or use sim3d objects or functions in MATLAB Online.

In addition, when using these blocks in a closed-loop simulation, all Simulation 3D blocks must be in the same subsystem.
