Ore Generation Disabler

The mod turns off Overworld ore generation before chunks are created, so ore features never run for the blocks listed in its tag. Because the check happens before generation, ores are not placed and then removed afterward. Ores are controlled through a block tag rather than fixed hardcoded lists, and any ore block added to the tag is detected and has its worldgen features disabled. Ores placed inside structures are removed as well. The mod works with vanilla ores and with many modded ores, and it is aimed at modpacks that use alternative ore generation systems.

Settings are kept in config files that appear the first time the game starts, and the tag can be changed there. Tag editing can also be done with datapacks or through KubeJS, and an example of adding blocks to the tag with KubeJS is covered in the author notes. The mod requires NeoForge and runs on client and server, so the server and every player need it. The latest NeoForge file is 1.0.1 for 1.21.1, published under the MIT License, and the code is not open source.
