We’ve talked a little bit about blueprint blocks in the past, but they’re probably a ‘later on’ feature. The aim is for blueprints to be an in-world item that encourages group building, not a tool or an editor to make building easy. This is what we have on the website:
“If you’re a born creator you can even place Blueprint blocks for your friends or other players to fill in. Blueprint helpers will receive gold for every block contributed.”
