This addon is designed to transfer .mcstructure files, which can be exported using a structure block, to another world or server. Simply name and save the structure with a structure block, export it, and then place the resulting .mcstructure file into the structures folder of the destination world or server.
Restart the server, and you can insert the structure with the command:/structure load (Name) ~~~
Alternatively, you can use another structure block, set it to Load, and enter the name of the structure.
