World space is my way of saying the area you made for walking around in, your ground level where it all happens before you get on the ship.
So when you board your ship you make a new one which allows the ship to very big if you want, so if you leave the world you are on to another one, you no longer have to worry about the size and distance of them.
When you get to the new place load another area in.
_____A____ship___ to _____ship____ to ______B____ship__
walk run on level A
enter ship
walk run on ship level
land ship exit to level B
walk tun on level B.
if this does not help, post saying it not what you are after, can someone please tell me how to do request in the first post.
