Description

Small mod that increases the size limit of the vanilla structure blocks.

As of version 1801.1.1 we now also expand the limit of the fill command!

Fill limit on newer Minecraft versions: Minecraft 1.19.4 added a vanilla gamerule for this limit, so on those versions set it with the gamerule:

  • Minecraft 1.19.4 – 1.21.10: /gamerule commandModificationBlockLimit <limit> (max 999,999,999)
  • Minecraft 1.21.11 and newer: the rule was renamed, so use /gamerule max_block_modifications <limit>

Mod version 1.16.5-1.0.5 and below:

Increases the size limit of the structure block from 48x48x48 to 127x127x127

Mod version 1.16.5-1.0.6 and above:

Increases the size limit of the structure block from 48x48x48 to 256x256x256
Added command to remove air blocks from structure files:
/structure clean <name>
(if structure is saved as 123 then name would be 123, if saved as sunekaer:123 name would be "sunekaer:123")
