A '''structure void''' is an [[invisible block]] that allows existing blocks to remain unchanged rather than be overridden when using the [[structure block]] to load a structure.

== Obtaining ==
Structure voids are available only using the {{cmd|setblock}}, {{cmd|fill}}, or {{cmd|give}} commands.

{{IN|Java}}, they are also available in the creative inventory if cheats are enabled.

== Usage ==
[[File:Shown Invisible Blocks.png|thumb|The difference between air (top left) and structure void (top right) when "show invisible blocks" is enabled.]]
Structure voids can be placed as part of a structure and are ignored when the structure file is saved. This results in the blocks at the location where the structure is placed being maintained and not being overridden. For example, if a player saves a 2 block high structure with air at the top and a structure void at the bottom, and loads it into a 2 block high area of stone, the top block becomes air but the bottom stays stone.

{{IN|JE}}, structure void blocks have no collision box but have a small hitbox. Additionally, they are invisible, but are displayed as red cubes when "Show invisible blocks" is turned on in Save mode inside a [[Structure Block]]. Blocks can also replace structure voids similarly to [[snow]] and [[grass]]. A [[piston]] can move a structure void, but the structure void pushed by the piston will turn into air.

{{IN|BE}}, structure void block's hitboxes are the same as a full [[block]], and, similar to barriers, appear when held by the player. Unlike ''Java Edition'', they can support blocks such as [[sign]]s, [[torch]]es, [[rail]]s and [[redstone wire]]. A piston cannot move a structure void.

As there is no collision box, [[entities]] can pass through, although [[liquid]]s cannot.
