Hi Nawrot,
thanks for the interesting ideas 
I agree with you that I should be pragmatic and fake it 
I’m now thinking which approach would be the best.
Moving everything minus the ship sounds interesting, although I’m wondering whether that would cause more intensive work to the engine than just moving the ship.
However it is a really interesting thought which I did not consider before. That would make the ship easily walkable inside.
I made some progress in the meantime and I actually have the interior of the ship bridge now implemented
Just it’s without collisions, so I cannot plan to visit it anytime soon
I could make the “ship interior” a separate level like you say, in this way I can visit it during a dedicated event.
On the other hand, for space games it would be great to be able to use the World Composition. If I choose to isolate the ship interior in its own level, I would lose that possibility to make an open world.
Interesting dilemma. I’m a bit counting on UE5 to solve that in the near future
Here is an image of how it looks like in game at the moment (I just finished composing it)
I’m really happy of the result, it looks better than I was hoping for 
And it was very simple and fast!
