About this Mod

Functions very similarly to jigsaw structures from modern versions of Minecraft, allowing for building complex randomised branching structures directly within your mod, without causing worldgen cascades or having to manually type out block IDs by hand.

Structures can be configured to spawn in any dimensions or biomes you choose.

Can be used to generate simple non-jigsaw structures too, enabling you to quickly replace any structures in your mod that are causing cascading issues.

Frequently Asked Questions

NBTStructureLib server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.7.10). You can switch loaders with one click in the panel.

Is NBTStructureLib compatible with forge?

NBTStructureLib officially supports forge for Minecraft 1.7.10. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with NBTStructureLib – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if NBTStructureLib consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
