You could use a space skybox (I am currently creating a couple of these right now) and texture the terrain with stars for space scene, or even completely transparent so the bottom of the skybox is seen. I am not sure at this stage about terrain using transparency for texture though, still, it could work and since I am in the space mood will look into it and see if there is a workaround
It might even be possible to texture the terrain black and use a large plane over it for starfields or nebula's, all the same for performance reasons it would be good to be able to remove terrain/water completely
You wont be doing any teleporting of any kind right now either since there are no commands/actions functional in the engine right now
Still, you could make a start (if you have the assets) on prototyping your levels.
This is all dependent on you placing your ship/station way above terrain level, if you plan to have it indoors then careful placement of windows etc would mean not having to do any of the above, I hope your models are collision ready too otherwise you got your work cut out for you so early in Beta without much in the way of ready made assets.
