Are you planning a case where two spacestations can collide into each other? If not, then a static collider is the way to go. They provide dead accurate collisions with super good performance.
You can move them around normally without any problems like everything else, they just can’t collide with other static which shouldn’t be a problem if you keep different spacestations away from each other.
It works pretty damn well for me:
I once asked why this works so well even when you move the static colliders (which shouldn’t be possible), but apparently nobody has a clue.
The only important part of code:
yourPhysicsControl.setCollisionShape(CollisionShapeFactory.createMeshShape(yourStationNode));
Then I suppose you can use dynamic mesh colliders for ships or compound shapes if you need more performance.
