So currently I trying to figure out away to make an Orbital Runway mod, at the cost of Electric charge get structural plats to give off a gravity field with a small SOI (like gravity plats from Star Trek). Two mods come to mind with this kind of ability Asteroids 2.4 and Anti-gravity room. Both the download links don't work and the authors seems to have abandoned it. Secondly I might be pushing it, an Atmospheric shell. If you don't know what they are there like a force field that holds in air on a space craft while still letting craft fly in and out an open door Darth Vader docks at death star. I personal was thinking of just locally enabling friction on other craft, vs fully simulating and Atmosphere. I don't know, any suggestions?
