I hear about this new seamless space stuff in SWRs now, and I'm curious about how this might be accomplished. I can't think of any codebases up for grabs that have it implemented, so I was thinking of removing systems and basically making one large system with larger xyz coordinates and spreading everything out inside that. Is this how it is typically done or is there something I'm missing here?

Most muds I've played with custom space do it in small grids of 15,20,10 ish. then larger grids of space. One game I played used a local area of like solar system xyz and then universal xyz aswell.
