Simulink freezes when using 3D Animation

Hello,

I am trying to run the aeroblk_HL20_UE demo.I have the Aerospace Blockset and Simulink 3D Animation installed. When starting the Simulation the "Simulation 3D Viewer" opens, but is completly black and I can only close it using the task manager. Beyond that, the Simulation is not running, since the Scopes are not filling up. After around 3 minutes of waiting this error pops up:

MATLAB System block 'aeroblk_HL20_UE/UE Visualization/Simulation 3D Scene Configuration/Simulation 3D Engine' error occurred when invoking 'resetImpl' method of 'Simulation3DEngine'. The error was thrown from '

'C:\Program Files\MATLAB\R2023b\toolbox\shared\sim3dblks\sim3dblks\Simulation3DEngine.p' at line 0

'C:\Program Files\MATLAB\R2023b\toolbox\simulink\ui\studio\config\m\+SLStudio\StartPauseContinue.p' at line 0

'C:\Program Files\MATLAB\R2023b\toolbox\simulink\ui\studio\config\m\+SLStudio\ToolBars.p' at line 0'.

Caused by:

3D Simulation engine interface read error.

Next to trying to figure out this error, I have tried to check all the requirements on this website: https://de.mathworks.com/help/aeroblks/unreal-engine-simulation-environment-requirements-and-limitations.html

These seem alright.

Does anyone have a idea why the demo could not be running for me? I am not finding any more relevant information online.

Hi @Timon Helmich,

It seems that the GPU may not be recognized correctly. I recommend reinstalling the necessary driver, as this might resolve the issue.

I hope this was helpful.
