AutoBuild
by oDilan
Players who build large structures can load a schematic file into AutoBuild, preview it as ghost blocks, and have the mod place it in the world.
What it does
AutoBuild, a Fabric mod by oDilan, loads .schem and .litematic schematic files and shows them as transparent ghost blocks before anything is placed. The preview can be moved, raised or lowered, rotated, flipped across the X and Z axes, and given a different transparency, so the position is set exactly where the builder wants it. A selection tool lets a player mark two corners of the world and export the chosen area as a schematic.
The placement mode decides how the structure is built: AutoBuild can place it automatically or leave the player in control of each step, and it is aimed at repetitive builds in both Survival and Creative. A community platform linked to the mod offers schematics to browse, profiles that load community builds directly, and a way to share creations. Several players can keep separate building states and settings. The mod requires Fabric API and is released under the MIT License. It is published for Fabric only, across 15 release versions 1.21 – 26.3, and runs on the client and server.
Key features
Schematic loading
Files in the .schem and .litematic formats are read and placed as a preview at the chosen position.
Ghost block previews
Structures appear as transparent blocks, so the builder can compare the plan with the surrounding terrain before building.
Preview transforms
The preview can be moved, raised or lowered, rotated and flipped across the X and Z axes, with adjustable transparency.
Selection and export
A built-in selection tool marks two corners of the world and saves the area as a schematic, kept locally or shared through the community library.
