Unreal Engine Simulation Environment Requirements and Limitations

Automated Driving Toolbox™ provides an interface to a simulation environment that is visualized using the Unreal Engine^® from Epic Games^®. Version 4.23 of this visualization engine comes installed with Automated Driving Toolbox. When simulating in this environment, keep these requirements and limitations in mind.

Software Requirements

• Windows^® 64-bit platform

• Visual Studio^® 2019

• Microsoft^® DirectX^® — If this software is not already installed on your machine and you try to simulate in the 3D environment, Automated Driving Toolbox prompts you to install it. Once you install the software, you must restart the simulation.

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

MATLAB Release	Unreal Engine Version
R2019b	4.19
R2020a	4.23
R2020b	4.23

Note

Mac and Linux^® platforms are not supported.

Minimum Hardware Requirements

• Graphics card (GPU) — Virtual reality-ready with 8 GB of on-board RAM

• Processor (CPU) — 2.60 GHz

• Memory (RAM) — 12 GB

Limitations

The Unreal Engine simulation environment 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

In addition, when using these blocks in a closed-loop simulation, all Unreal Engine simulation environment blocks must be in the same subsystem.
