Structure blocks are one of the few things in Minecraft that do not generate naturally but can be obtained using commands. The command for getting a structure block is "/give @p structure_block 1".

Used in cohesion with the structure block, the structure void is an invisible Minecraft block that prevents blocks from being overridden when a structure block manually generates a structure.

Added a button in the GUI that generates a jigsaw structure starting from the jigsaw block, using given generation depth. Expanded the max size per axis of Structure Blocks from 32 to 48.
