I am using MATLAB R2024a and trying to use the UAV Toolbox Interface for Unreal Engine Projects.
My goal is to simulate UAVs using Simulink with Unreal Engine 4.26 and create custom scenes/maps.
I have completely uninstalled UE 5.1 and only UE 4.26 is installed.
Despite performing the following steps, the problem persists:
【What I’ve Tried】
- Deleted the following folders:
C:\ProgramData\MATLAB\SupportPackages\R2024a
C:\Users\<Username>\AppData\Roaming\MathWorks
C:\Users\<Username>\AppData\Local\MathWorks
2.Launched MATLAB as Administrator
3.Reinstalled "UAV Toolbox Interface for Unreal Engine Projects" via matlabshared.supportpkg.install(The installation took over 40 minutes)
4.After reinstallation, I ran the following:
which sim3d.installUnrealEnginePlugin
→ Not found
sim3d.utils.copyExampleSim3dProject("C:\myUAVMap")
→ Project is created but only compatible with UE 5.1 (not UE 4.26)
+sim3d folder is missing, and no valid plugin was installed.
5.Even though UE_5.1 was uninstalled, executing sim3d.utils.copyExampleSim3dProject causesC:\Program Files\Epic Games\UE_5.1 to reappear unexpectedly.
【Issues】
- sim3d.installUnrealEnginePlugin is not found
- +sim3d folder is not created under the SupportPackages directory
- .uproject cannot be opened with UE 4.26 (version mismatch error)
- Reinstallation does not solve the issue
I have tried everything I could think of to reset and reinstall in a clean environment,
but the correct sim3d plugin and UE4.26-compatible project are still not available.
Any advice, solutions, or official fixes would be greatly appreciated.
Thank you in advance.
