Unreal Engine Simulation Environment Requirements and Limitations

UAV 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 (recommended)

Integrated development environment (IDE)

Visual Studio®

Visual Studio Code

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.

If you are customizing scenes, you must install Unreal Editor. In addition, verify that your Visual Studio and Unreal Engine project versions are supported by your MATLAB® release.

Limitations

The 3D simulation engine is not supported on Mac platforms.

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.
