Cleaner Cave Mining

During initial chunk generation, the mod checks each block that a world feature places and swaps the decorative variants for standard stone or deepslate. Players who want tidier cave walls and fewer blocks to sort out in their inventory can enable it without changing how ores or structures are placed. A configurable list controls which block types are replaced, and each one can be toggled on its own.

For cases where the world already exists, a server operator can run a reload command that sweeps the loaded chunks and substitutes the target blocks in them. A stonecutter conversion option also lets builders turn plain stone back into the removed variants when a decorative build needs them. Master settings are registered on the server and can lock the multiplayer configuration screens, so clients cannot drift from the server setup.

Cleaner Cave Mining is a standalone Fabric mod that integrates with PCKR Engine, which handles the registration of individual block settings. Every player and the server need a copy of the mod. Files are published for Fabric only, for game version 26.1.2, and the mod is released under All rights reserved, so it is not open source.
