That's how I thought it was done thanks. I was hoping for a world size one(multi cell) but was willing to settle with a few large room size as I've only built one station and 4 outpost's so far but if I could do world size one then I can have my astroid belt (long way off), so it's just a simple skybox texture of what file type? and would you know anything about how to switch gravity off in the engine ? If not no worries. also i love your bridges and stair's mod..
