by 4tubborn

What it does

Block Morph is a minigame and mechanics mod that transforms customized block structures. A datapack handles the transformation, so individual blocks and whole structures can change into other blocks in the world. Players can sneak around a morphed block with friends, and the mod includes a become-block option that turns the player into a block.

The mod requires the Bookshelf Suite Bundle, which must be installed alongside it. Bookshelf is available in two ways, and the author asks that users choose one of them. Only the server has to run Block Morph, while players may leave it out. The mod is released under the MIT License and is open source, and its source code, issue tracker and wiki are public. Files target the 1.21.9 – 1.21.11 range, and the latest build is 0.3.4+mod for 1.21.11, published as a beta on 2026-09-24. The first release date was 2026-07-21 and the last update was 2026-10-15.
