Hello, SInce the system uses it's own simplified mesh you can do whatever you want with colliders. You could have 1, 10 or 20 colliders as a part of the ship. The only thing that is required is to have at least one since rigidbodies require that. So you can have separate collider for hull, cabin, small parts, etc. One suggestion is to create colliders in modelling software as it is easier that way, but you could make everything out of primitive colliders as far as DWP is concerned.
