Hi,

I have installed "Vehicle Dynamics Blockset Interface for Unreal Engine 4 Projects" and trying to run the Custom method to open the AutoVrtlEnv project in Unreal.

I have followed the procedure https://in.mathworks.com/help/vdynblks/ug/support-package-for-customizing-scenes.html, installed UE4.19 (tried with 4.19.2, 4.19.0, 4.19.2_release tags from Unreal github directories and buiding the executable as EPIC Launcher is having only UE4.24 and UE4.23 versions as of now).

When tried to open the project from Matlab environment, I am getting the following errors:

Missing or incompatible:

2. If I choose No in the above option (step 1) then getting the error as failed to load:

3. If I press OK in step 2, the Epic launcher app is launched which provides only the latest 4.24 version launch option.

4. If I press Yes in step 1, the AutoVrtlEnv project is opened but having the Load errors as below:

5. Also having the MathworksSimulation Plugin disabled:

6. If I try to enable, the Unreal application is asking for a restart and the same sequence continues. Below snapshots are for your reference on the unreal version being used:

Note that the source is built using the Github https://github.com/EpicGames/UnrealEngine/tree/4.19. I also tried with https://github.com/EpicGames/UnrealEngine/tree/4.19.2-release and https://github.com/EpicGames/UnrealEngine/tree/4.19.0-release. But all are providing the same above errors only.

7. I tried opening the AutoVrtlEnv project using the latest UE 4.24.1. But getting the following error:

8. If I provide No, then the project is not loaded. If I press Yes, then getting the following error:

Request your support in adding the MathworksSimulation plugin inside Unreal engine and use the custom mode to edit the scenes in VehicleDynamicsBlockset.

@Nishan Neeko, Can you specify why this is failing? Is there a fix planned?

Hi Manoj, unfortuantely this is a technical limitation that I don't have much insight to offer into. The team may consider implementing a more robust interface mechanism in a future release that doesn't require this manual step.

the AutoVrtlEnv unreal project must be opened from matlab command line, or form simulink block [Simulation 3D Scene Configuration] -> [Open Unreal Editor].

Because the simulink is not linked to Unreal Editor, when u double click xxx.uproject to open the AutoVrtlEnv project, the error happens. as ue editor can not find matlab plugins.

matlab command line: e.g

path = fullfile('C:','Local','myProject','myProject.uproject');

editor = sim3d.Editor(path);

open(editor);
