Just wait... There's only one transition that qualify's as a loading screen: the hyperspace jump between systems. Once you're in a system, if you're patient enough, you can fly anywhere in normal space.Ok, so how do i make it do that without the loadscreen?
Granted, most interplanetary trips will take years with even the fastest ship, but flying from a low orbiting station down to the surface of a planet can be done in a few hours, assuming you're patient enough.
