Issue using sim3d.util​s.copyExam​pleSim3dPr​oject()

Note: I am using Matlab R2023a.

I am trying to customize some Unreal Engine scenes to use with the Automated Driving Toolbox. I was following this documentation: Install Support Package for Customizing Scenes - MATLAB & Simulink (mathworks.com). I have successfully installed Automated Driving Toolbox Interface for Unreal Engine 4 Projects within Matlab.

I tried using the

sim3d.utils.copyExampleSim3dProject("C:\project", VerboseOutput=true);

function, but that results in the following error:

Copying C:\ProgramData\MATLAB\SupportPackages\R2023a\toolbox\shared\sim3dprojects\spkg\project\AutoVrtlEnv to C:\project\AutoVrtlEnv

Creating C:\Program Files\Epic Games\UE_4.27\Engine\Plugins\MathWorks

Ensuring C:\project\AutoVrtlEnv\AutoVrtlEnv.uproject is writable

Error using fileattrib

The system cannot find the path specified.

Error in sim3d.utils.copyExampleSim3dProject

Error in sim3d.utils.copyExampleSim3dProject

I also tried to do it manually following the documentation, but the specific files that are specified do not exist on my computer. There is no MathworkSimulation folder anywhere on my machine.

Thank you for any assistance.

Hi Upneet,

You should be able to verify the existence of the "AutoVrtlEnv.uproject" file under "C:\ProgramData\MATLAB\SupportPackages\R2023a\toolbox\shared\sim3dprojects\spkg\project\AutoVrtlEnv\"

If this file does not exist, it means the support package did not install correctly.

If you believe the installation was done correctly, I would recommend reinstalling MATLAB and the support package using the following steps:

1. Navigate to the following directory “C:\Program Files\Epic Games\UE_4.26\Engine\Plugins\”
2. Find the folder “MathWorks” and delete the entire folder with its contents.
3. Navigate to the directory “C:\project_unreal”
4. Remove all contents from the folder (the folder itself does not need to be deleted)
5. Uninstall MATLAB
6. Reinstall MATLAB (be sure to include the Automated Driving Toolbox and any other necessary toolboxes)
7. Install the support package

I hope this helps,
