NeoStructureMapper
by DraGome
NeoStructureMapper lets players preview, annotate and export multi-block structures from a right-click panel on any block, and it is published for Forge and NeoForge.
What it does
Right-clicking a block opens an annotation panel. From there a player can type text, pick from sixteen colors, and attach notes to the parts of a structure. A preview shows the three-dimensional model of a selection and of the sub-selections a block is part of. Hovering the mouse over an annotated block shows its annotation text in the inventory.
The mod is built around the main function of mapping a multi-block build and exporting it. Its features can be heavy, so the author advises thinking twice before installing it on a large modpack or server. Installation covers the server and each player's game. The code is under the MIT License and is open source, with public source code and an issue tracker. Files target 1.20.1 and 1.21.1, and the latest Forge and NeoForge builds were published on 2026-06-08.
Key features
Annotation panel
Right-clicking a block opens a panel where text annotations can be typed and attached to the structure.
Sixteen colors
Annotation text can be drawn in one of sixteen colors to tell notes apart.
Three-dimensional preview
A 3D model shows the selected structure and the sub-selection a block is part of before export.
Renamable selections
Main selections and sub-selections can each be renamed by right-clicking them.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Who it’s for: Builders and server owners who map multi-block structures and want notes attached to blocks. Because the author warns about its load, it suits smaller worlds and test servers more than large modpacks.
How it compares
Inner Voice is a Forge and NeoForge mod for 1.20.1 – 1.21.11 that also runs on client and server, but it is closed under All rights reserved. Create: Schematic Preview is a NeoForge-only mod for 1.21.1 that runs on the client alone and is open source under the MIT License, so it does not handle server-side structures. Export Stats is open source under the Apache License 2.0 and covers Fabric, Forge and NeoForge for 1.20 – 26.2, which is a different purpose.

DISCLAIMER: The project is ENTIRELY vibe-coded by me using ChatGPT. Although the features provided are not likely to cause trouble, think twice before using it in a large modpack/server. In the center of the GUI is a 3D model of the selection, you can rotate, zoom, and pan. Additionally, you can press "-""=" to peel…
