About this Mod




⚠️ WARNING: This mod is currently in early testing/alpha stage and is heavily subject to change. Expect bugs, unfinished features, and frequent updates. Not recommended for survival worlds yet. ⚠️

🪨 Slabbed — Natural Cave Slabs

Slabbed is a world generation mod that makes underground exploration feel more natural and immersive. Instead of awkward 1-block jumps everywhere, caves now have subtle stone slabs placed at step edges — making traversal smoother while keeping the raw, natural feel of Minecraft caves.

✨ Features

  • Automatic step slabs -> Slabs are placed at the base of 1-block-high steps in caves, ravines and mineshafts, making them easier to walk through
  • Staircase detection -> Long staircase-like cave sections get slabs placed every other step, preventing cluttered or unnatural-looking sequences
  • Material variety -> Slabs match the surrounding stone type (Stone, Deepslate, Tuff, Andesite, Diorite, Granite) with rare variants for a natural look
  • Mob & lighting friendly -> Only bottom slabs are placed, meaning mobs can still spawn normally and lighting is unaffected
  • Performance conscious -> Built with a per-chunk slab limit and minimal block update propagation to keep worldgen fast
