Space ship that moves but the player can still walk around

You understood correctly, however this method wont work because there will be more than one ship flying at the same time… I had the idea of when you enter the ship your pawn is TPed to another level which is the ship interior. After that use cameras etc to create the illusion that your really in the ship. I am just unsure if its all possible…I guess another example of what I am imagining would be like the tardis…the inside would be a different level than the outside because its bigger inside. Does that make sense?
