Hello again,
The ring has been built now to guide the asteroid belt, and a region has been created for permissions.
If you would like to work on this project, let me know ingame and I'll add you to the region.
The look I'm going for with the asteroid belt is many small objects floating in an orbit.
The guideline I'm working with is "not more than 7 blocks in size, and not more than ten blocks away from the orbit ring". The asteroids do not have to be round, but please no square boxes!
As far as materials go, generally speaking I'll be using stone and ice blocks, but I'm fine with almost anything, including a few rainbow asteroids as jennythegreat has mentioned ingame.
Please join on this build, I think it would be fun if everyone built at least one asteroid up there, and put a sign on top with name etc.
cheers!
*edit* to reach this site, do /warp build and fly up, look for the stone ring outside the planets above build spawn.
