Description
A simple, quality-of-life mod that removes the vanilla restrictions on Minecraft's Structure Block, unlocking its true potential for builders, server admins, and creative minds. Save, load, and manage massive structures with ease and precision!
Features
Have you ever tried to save your megastructure, sprawling city, or complex redstone contraption, only to be stopped by the frustrating 48x48x48 block limit? This mod fixes that and adds powerful new tools for on-the-fly manipulation.
Fully Configurable Size Limit: The maximum size of a structure is increased from a tiny 48x48x48 to a massive 512x512x512 blocks by default. You can change this limit in the config file to whatever your machine can handle!
Extended Render Distance: The structure's bounding box is now visible from much further away, increased from 96 to 256 blocks by default (also configurable). No more running back and forth to see if your alignment is correct.
"Re-open Last" Keybind: A configurable keybind (default: G) allows you to instantly re-open the GUI of the last Structure Block you interacted with, no matter where you are in the world. A huge time-saver!
Dynamic Grid Resizing (New!): Intuitively resize the structure area without opening the GUI! Simply look at a face of the bounding box and use the new keybinds (default: Up/Down Arrows) to push it away or pull it closer. It works from both inside and outside the box.
Dynamic Grid Shifting (New!): Nudge the entire structure area one block at a time. A new keybind (default: V) moves the bounding box in the direction you are looking, allowing for precise, quick positioning.
Client + Server: This mod is required on both the client and the server to enable all features.
Lightweight & Vanilla-Friendly: No new blocks, no new items. Just powerful tweaks to a vanilla feature that make it infinitely more useful.

Configuration
This mod is fully configurable. After running the game once, a config file will be generated in config/structure_block_unlimiter-common.toml.
#The maximum size (per axis) that a Structure Block can save or load. #Vanilla default is 48. # Default: 512 # Range: > 1 max_structure_size = 512 #The distance in blocks from which the structure's bounding box is visible. #Vanilla default is 96. # Default: 256 # Range: > 16 render_distance = 256The keybind can be changed in the standard Minecraft controls menu, under the category "Structure Block Unlimiter".
