Error when running Unreal Engine

Hello, I have MATLAB R2020a, with Vehicle Dynamics Blockset, Automated Driving Toolbox and all other required prerequisities, I am trying to run a 3D simulation based on "Straight Road Scene" with my own Unreal Environment, just for testing purposes, I have opened the Unreal Editor and started the Unreal game (via Play button) but when I try to run the simulation i got this error message:

In the Simulation 3D Scene Configuration block, you set the scene source to 'Unreal Editor'. In Unreal Editor, select 'Play' to view the scene.

MATLAB System block 'UnrealSimulinkIntegration/Simulation 3D Scene Configuration1/Simulation 3D Engine' error occurred when invoking 'resetImpl' method of 'Simulation3DEngine'. The error was thrown from '

C:\MatlabInstalationPath\sim3dblks\sim3dblks\Simulation3DEngine.p at line 0'.

Caused by:

• 3D simulation engine startup error. Start the 3D simulation engine editor.

Do you have any tips how can I fix this?

Thank you very much for any response

Hello, do you have any progressing now? I meet the same question and can't find the answer on the Internet.

I also suffered from the same problem.

It looks like you first need to read the project in the workspace with Matlab commands.

example）

env = sim3d.Editor('C:\AutoVrtlEnv')

[status,result]=open(env)

If you're trying to connect Simulink to a custom Unreal Engine scene, these instructions should help:

I second Mike's recommendation. This error is usually driven by improper setup. If this is setup correctly, I would suggest making sure MATLAB is on its latest release. See this link for another discussion on a similar issue.
