mcteunofficial
by mattya
MCTEUnofficial is an unofficial build of the MCTE world editing tool, letting players copy, fill, shrink and rotate areas through a miniature block system.
What it does
Players use the editor tools to edit large areas quickly. A miniature block system handles the operations: a selected region can be filled with one block type or with a random mix of several, and structures can be shrunk or rotated freely, without the limits of normal block placement. Block copying and miniature creation are part of the same toolset.
The mod suits map creators and builders who want more advanced building tools than vanilla Minecraft offers, especially for large-scale structures and detailed decorations in compact form. Its code descends from an earlier tool made by a single developer. Files are published for Fabric and NeoForge for 1.21.1, and the environment is client and server, so the server and every player need the mod. The mod is released under All rights reserved and is not open source.
Latest builds are fabric_alpha8 for Fabric and neoforge_alpha8 for NeoForge, both dated 2026-07-28 on the alpha channel. The mod was first published on 2026-05-04 and last updated on 2026-07-28.
Key features
Area fill
Selected areas can be filled with a specific block, or randomly filled with several block types in one operation.
Miniature block system

Free rotation
Structures can be rotated freely, without being limited to the orientations normal block placement allows.
Block copying
Blocks and miniature structures can be copied, supporting the creation of detailed decorations in compact form.

Use cases
Large-scale building
Map creators can edit vast areas and build large structures using the miniature system instead of placing each block by hand.
Who it’s for: Map creators and builders who want advanced world editing tools beyond vanilla Minecraft, and server owners who run building projects that need both sides to have the mod.
How it compares
EZCoords is a Fabric mod for 1.19.2 – 1.20.2 that runs on the client only and is open source under the GNU General Public License v3.0 only, so it does not cover world editing for 1.21.1. Simple Blueprints is a client-side Fabric mod under the MIT License for 1.21.11 – 26.3, and it is open source. Multi World Borders Unofficial is a server-side Forge and NeoForge mod for 1.18 – 1.20.6, released under the MIT License. None of these targets 1.21.1 alongside a world editor.
