Limitless Structure
Limitless Structure removes the vanilla size limits on Structure Blocks, so a single structure can be saved far larger than the default allows.
What it does
Structure Blocks in vanilla Minecraft are capped by hardcoded size offset limits. This Forge mod lifts those caps and makes saving very large builds possible. It changes the Structure Block screen, its text input and the networking packets that carry the data, with data validation kept in place, so both sides need it installed to work correctly. Files are published for Forge 1.20.1 only, and the mod is released under the MIT License, not as open source.
Key features
Larger structure saves
Structure Blocks accept sizes beyond the vanilla offset limits, allowing much larger structures to be saved.
Validated networking
Changes to the Structure Block screen and its packets keep data validation in place on both sides.
Performance warning
Saving and loading very large structures creates big NBT files and can cause temporary server lag and TPS drops.
Compatibility
