Blight

Blight adds decorative blocks to Minecraft 1.20.1 in an industrial, decaying style, with mesh blocks, stairs, flooring, grate-like blocks and black lanterns. Its design draws on the Befoul mod, and the theme centers on a world where forgotten lands slowly rot and corrupt over time. The blocks are meant to decorate abandoned factories, ruins and similar scenes.

New materials such as Blackened Iron are needed to craft the newly added blocks. Blackened Iron comes from smelting iron in a blast furnace, and it is the base material for most of the blocks added by Blight. Burnt Grass is a grass-type block that appears after a fire is put out on a grass block. The mod was rebuilt from scratch with manual scripting after an earlier MCreator version, and the author expects some bugs because the project is still in progress.

Blight runs on both the client and the server, so the server and every player need it. Files are published for Fabric and Forge for 1.20.1, and the latest build for each loader is 0.1.1, released 2026-02-12 on the alpha channel. The mod is licensed under the MIT License and is not open source.
