Structure Block Unlimiter
by KantraCity
Structure Block Unlimiter removes the size restrictions on the vanilla Structure Block, so builders can save and load far larger structures.
What it does
The vanilla Structure Block caps the size of the area it can capture. This NeoForge mod lifts that cap and raises the render distance of the block's outline, which makes it practical to save a sprawling city, a large build or a redstone contraption in one piece. It is open source under the MIT License and has source code publicly available.
Key features
Uncapped structure size
The 48 by 48 by 48 block limit of the Structure Block no longer applies, so larger areas can be captured.
Wider outline rendering
The Structure Block's boundary box is drawn at a greater distance, so the edges of big structures stay visible while editing.
Tools for large builds
Adds new blocks, items and on-the-fly tools for saving, loading and managing massive structures with more precision.
