How to use the Automated Driving Toolbox to render car models in Unrealengine

A scenario was created using the Automated Driving Toolbox. It was confirmed that the vehicle moved according to the scenario in UnrealEngine 4.27.

Next, the car created in Blender was imported into UnrealEngine. Next, uasset was added to the "type" parameter of the Simulation 3D Vehicle with Ground Following block, but an error occurred and it could not be executed.

・The uasset was set to a Skeletal Mesh

・The path of the uasset was the path that was obtained by copying the mesh reference in the UnrealEngine content browser (/Game/Alphard/Alphard.Alphard)

Hi Don,

What version of MATLAB are you using? Are you using a Simulation 3D Terrain Sensor in your model? There might be an issue with the way you have configured your skeletal mesh in Blender. I assume you have been following the guide here:

https://www.mathworks.com/help/driving/ug/prepare-custom-vehicle-mesh-for-the-unreal-editor.html

Here is a video also that might be helpful to make sure you don't miss anything:

Would you be able to share this custom uasset here? If not, I would recommend reaching out to MathWorks technical support at [e-mail] so that they can reproduce this issue and help you resolve it.

Thank you for the great guide and video. I didn't know the video existed.

I will try.
