About this Mod

AutoBuild

AutoBuild is a Fabric mod for loading, previewing, transforming, and automatically building Minecraft schematics.

Load a .schem or .litematic file, position the ghost preview exactly where you want it, choose a building mode, and let AutoBuild place the structure while you remain in control.

AutoBuild also connects to its own community platform, where you can discover schematics, share creations, create a builder profile, and load community builds directly into the mod.

Frequently Asked Questions

AutoBuild server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.2). You can switch loaders with one click in the panel.

Is AutoBuild compatible with fabric?

AutoBuild officially supports fabric for Minecraft 26.2, 26.1.2, 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with AutoBuild – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if AutoBuild consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
