Increasing boundary limits in Unreal engine

Hi, I am performing co-simulation of a plane in Matlab something like this:

For visulization, I have chosen the Griffiss airport scene.

When I fly the plane above 1.4 km, it hits an invisible boundary and starts tumbling. For my tests, I need to fly the plane up to 10 km.

Can someone please let me know how to get rid of this invisible boundary so that I can fly the plane up to 10 km?

Hi Vivek, there shouldn't be any invisible boundary. For example, here is the default aircraft flying at an altitude of 14km:

The tumbling might be caused by something else in your physical model, could that be possible? In general, there shouldn't ever be any boundaries around an Unreal scene, I can even place the plane at 140km above with no problem.

Hi Nishan,

I had made a few changes to the Griffiss airport scene. May be that created the issue. Is it possible for you to share the .umap of your Griffiss airport scene?

Hi Vivek, assuming you have the correct support package downloaded already, I'd recommend creating a fresh copy of the AutoVrtlEnv project by deleting the plugins from the Epic Games folder and calling sim3d.utils.copyExampleSim3dProject

1. Navigate to the following directory “C:\Program Files\Epic Games\UE_X\Engine\Plugins\Marketplace”
2. Find the folder “MathWorks” and delete the entire folder with its contents.
3. sim3d.utils.copyExampleSim3dProject("C:\project")

Let me know if that works,

Hi Nishan,

I did that and still same issues. I checked the physics model and it definitely comes from interaction with unreal engine. I get the same behavior when the plane goes out of the land boundaries in X and Y directions. It hits an invisible boundary and the plane starts to tumble uncontrollably.

Hi Vivek,

Can you tell me a little bit more about your workflow? Are you relying completely on the physics from Simulink and simply specifying the translation and rotation of your actor or are you leveraging Physics in Unreal as well?
