Unreal Engine Simulation Environment Requirements and Limitations

Vehicle Dynamics Blockset™ 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®.

Software

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.

In you are customizing scenes, verify that Visual Studio and your Unreal Engine project is compatible with the Unreal Engine version supported by your MATLAB® release.

Limitations

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.

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.
