Suggestions how to run a functioning spaceship in Sims 4?

I made a spaceship once and used double walls around the exterior to make it look like they were actually in space when inside the “ship.” Put windows on the inner walls and a cc space-themed wallpaper on the inside of the outer wall. Put a few dim lights in the in-between space to show off the wallpaper. You can even find some animated wallpaper to make it look more realistic.
