The second set in OpenForge City Streets has been released. This set includes brick sidewalks, as well as brick sidewalks with larger stone curbs. So far only the curbs that are straight are included.
We have also decided to break out the bases into their own thing. We are no longer adding the bases to each thing, as it's created some confusion, and supporting all the variations (3 sizes for the squares * 4 connection options = 12 variations per size) means every release has a ton of files in it. This should help make things be a bit cleaner. If any release adds new base sizes that would be needed, that will be updated.
