Hello. This plugin would require multi-verse core as well as worldedit. Say you wanting a build, a tower with loot in it. But, You wanted it random generated in a world. You would, Select the build with worldedit and do /Rw addstructure (structure name) Then, You could create a mock world and add structures to it (Before the world is created) Example: /Rw add structure Tower /Rw add world Survival /Rw add structuretoworld Tower Survival /Mv create Survival The world would generate with the structures randomly generated inside of them
