No Structure Limits [NSL]

Have you ever spent hours building an amazing, massive dungeon, only to watch Minecraft cut it in half when you load it into the game? Or maybe you've tried to use Jigsaw blocks, but the 128-block limit ruined all your plans?

Well, I got tired of this. So I broke the rules.

No Structure Limits (NSL) is a lightweight utility mod that completely removes the vanilla restrictions on structure generation and the Structure Block.

What does this mod do?

Removes the 128-block limit: Vanilla Minecraft limits Jigsaw structures to a maximum of 128 blocks from the center. NSL removes this limit entirely. You can now set max_distance_from_center to 512, 1024, or even higher.

Fixes clipping: Vanilla engine only scans 8 chunks around the structure start. NSL expands this scan radius, ensuring that your massive structures generate completely, without missing rooms or cut-off walls.

Unlocks the Structure Block: The vanilla Structure Block is capped at 48x48x48. NSL removes this limit, allowing you to save and load structures up to 255 blocks in size.

No Crashes: Built with custom Mixins to safely bypass the codec limits and chunk generation errors, so you don't have to worry about your game crashing when a huge structure loads.

Why do you need this?
If you are a modder, a map maker, or just someone who wants to build a gigantic underground city, this mod is for you. You no longer have to split your structures into tiny pieces using Jigsaw blocks (which I personally hate). Just build it, save it, and let NSL handle the rest.

Important Warning:

This mod removes vanilla safety limits. Generating colossal structures will require more RAM and CPU power.
