How do I use a non-kinematic rigibody object with a non-convex mesh collider?

Unity Engine

I am working on a realistic space game and I need hyper-realistic physics. I understand what the error ‘Non-convex MeshCollider with non-kinematic Rigidbody is no longer supported since Unity 5’ means, but I can’t give up neither. Convex collider makes my complex spaceship collider into an oversized triangle, making the physics behave wierd. I also need a rigibody not to be kinematic, as I need the ship to collide properly. Is there any other solution other than:

A) Recoding the physics engine
B) Creating a custom collider with primitive collider shapes

?

Decompose your concave mesh into convex meshes using something like this: GitHub - Unity-Technologies/VHACD: The V-HACD library decomposes a 3D surface into a set of "near" convex parts.

I did install the plugin using the provided tutorial, but I can’t figure out it’s usage. I have discovered a VHACD script component, but it does not appear to make the collider. Turning the Mesh Collider does not help. Is there a step or a component I am missing?

Edit: I searched some forums, where everyone was confused on how to do it. I even tried cloning it and installing it as a local version but nothing

No idea, I’ve never personally used it.

After extensive research I came to a conclusion that the project was/is anabandoned and is no longer supported and working in the newest versions of Unity (I am using 2022.8f1). Is there any other option for me?

Search for Convex Decomposition libraries either free or on the Asset Store.

Thanks! I found a V-HACD fork by rorygames working with my version of unity. Thank you so much for the support!
