Incompatible version of 3D Simulation engine

[OCEClub]

i followed the steps outlined in the PDF, I hit run, Unreal opens for a bit then closes. matlab thows this error:

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

Caused by:
Incompatible version of 3D Simulation engine: 25.1.0.

what version should i have? what version do i have? how do i get that version?

Hi there, we encountered a similar error, I didn't take a picture so I can't remember the exact wording, sorry. I fixed it by running this command in the matlab command window.

setpref("Simulation3D","PluginVersion","25.1.0")

You could try changing the version number in the command if this doesn't fix it.
