A promotional banner for the Minecraft mod "SLABBED". The word "SLABBED" is written in large, white, blocky letters with a thick black outline at the top center of the image. The scene is set in a vibrant Minecraft landscape at sunset, featuring rolling green hills and trees under a sky with soft orange and blue hues. In the foreground, several stone slabs are placed on the grass, serving as pedestals to showcase the mod's functionality. Various items that normally require a full block for placement are shown sitting directly on these slabs: * A red bed and a crafting table. * A lit torch and a soul lantern. * A flower pot containing a white oxeye daisy. * A wooden door standing upright. * A chicken standing on a slab in the lower right. The image effectively demonstrates the mod's core feature: allowing players to place furniture, lighting, and other objects on the top surface of slabs.

FINALLY! Place items on slabs!

Hang lanterns from slabs! Stack blocks on slabs! Stack blocks on those blocks on those slabs!* Your slabs finally get the love they deserve 💖

*Slabbed is still in beta. Expect some rough edges while it continues to improve and expand.

✨ New in Beta 4

Slabbed 0.2.0-beta.4 is a major interaction-stability update.

This release improves targeting, hitboxes, visual contact, placement acceptance, and server-side interaction for many common slab-supported building objects. A lot of previously cursed behavior — "the object looks like it's there, but Minecraft thinks it's somewhere else" — has been cleaned up.

Big improvements landed for:

  • Compound slab → block → slab → block structures
  • Reduction in the dreaded ghosts (culled block faces)! 👻
  • Torches, candles, lanterns, chains
  • Flower pots
  • Buttons, trapdoors, doors, fence gates
  • Fences and walls
  • Stairs and ordinary blocks in audited slab-supported setups

This doesn't mean every item and block is fully covered — it means these common building cases got the most direct testing and stabilization work this beta.

🧱 What Slabbed does

In vanilla Minecraft, slabs are awkward supports. Objects look like they should sit on them, attach to them, or interact with them — but the game's placement and hitbox rules disagree.

Slabbed makes those situations feel consistent:

  • Objects sit on slab-supported surfaces more naturally.
  • Supported objects visually land where they actually are.
  • The crosshair targets the visible object instead of the wrong support block.
  • Common building objects behave sensibly around lowered slab structures.
  • Less floating, snapping, ghosting, and interaction mismatch.

The long-term goal is broad slab support, but Slabbed expands carefully — category by category, by proven behavior.

⚠️ Still rough

These categories haven't gotten focused work yet and may misbehave:

  • Glass panes and bars
  • Carpets and other thin top layers
  • Rails and redstone
  • Signs and specialized attachments
  • Custom slabs and heavily custom modded blocks
  • Certain unusual slab-placement edge cases

There's also a known slab lane-grammar issue where some placement or break neighbor updates can visually re-resolve lowered slab lanes in specific stacked builds. It's tracked separately from per-block fixes.

If something looks wrong, it probably is — and it's probably worth reporting.

Compatibility

  • Minecraft 1.21.11
  • Fabric + Fabric API
  • Singleplayer and server-side

Mods that heavily customize block shapes, rendering, collision, placement, or models may need dedicated compatibility work. Countered's Terrain Slabs is not yet compatible, but it will be addressed in a future update!!

🐛 Reporting bugs

Bug reports are super duper helpful! The most useful ones include:

  • Minecraft, Slabbed, Fabric Loader, and Fabric API versions
  • Other installed mods
  • Exact placement steps + what you expected vs. what actually happened
  • A short screenshot or video — especially of the crosshair, placement attempt, or visual mismatch

🛠️ What's next

  • More supported object categories, added carefully
  • Tighter agreement between visuals, outlines, and raycasts
  • Remaining slab-lane edge cases
  • Better compatibility with modded blocks
  • Fewer ghost blocks and wrong-target moments
  • The much asked-for ports!! MC 1.21.1 is currently in the works :)

Slabbed's goal is simple:

Things should sit where they look like they sit.

Minecraft just makes that surprisingly complicated.

💖 Thanks!

Slabbed is made by one person and is still actively evolving. Every bug report, screenshot, video, and weird edge case helps make slab-supported building better. Thank you for playing with Slabbed and helping me make it what it is!
