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 0.3.0 — Countered's Terrain Slabs compatibility!! 🎉
Remember when I said Terrain Slabs compat was coming "in a future update"? THE FUTURE IS NOW. ✨
The much asked-for feature has arrived! With Countered's Terrain Slabs installed, terrain slabs become proper, first-class support:
| Terrain Slabs support | Highly recommended: Countered's Terrain Slabs | |
|---|---|---|
| 🪶 | Flush, not floaty | Blocks, lanterns, torches & chains on terrain slabs lower to sit flush — no more hovering |
| 🧩 | Combined slabs | Put a vanilla slab on top of a Terrain Slabs slab and they merge into one continuous surface.* |
| 🔌 | 100% optional | Runs exactly the same with or without Terrain Slabs. No Terrain Slabs? No problem 👍 |
| 🕳️ | No more world gaps | Slabbed used to tear see-through holes in Terrain Slabs terrain, straight into the void. Gaps have officially been de-gapped 😎 |
And it's not just the compat — this release sands down a LOT of the cursed jank:
| What got better | What it means for you | |
|---|---|---|
| 🎯 | Better targeting | Your crosshair and the selection box finally agree on where a lowered block actually is |
| 👻 | Fewer ghost windows | Less staring into the void through a lowered block! (I call these 'Doom Windows', or 'DODOs' :P) |
| ⬇️ | Less snapping | Freshly placed blocks stop doing the little dance - IYKYK |
| 🧱 | More multi-stacking | Objects & full blocks on combined slabs sit flush, and vanilla slabs chain neatly when stacked |
*One-way for now: combining works when the vanilla slab sits on top of the Terrain Slabs slab — they lower and merge flush. The reverse (a Terrain Slabs slab on top of a vanilla slab) doesn't lower yet. It's a known limitation and on the list! 🛠️
🧱 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 haven't gotten focused work yet and may misbehave:
| May misbehave | ||
|---|---|---|
| 🪟 | Glass panes & bars | not slab-aware yet |
| 🧶 | Carpets & thin top layers | excluded from offsets |
| ⚡ | Rails & redstone | visual / connection edge cases |
| 🪧 | Signs & specialized attachments | not specially handled |
| 🎨 | Heavily custom modded blocks | may need dedicated compat |
And two Terrain Slabs edge cases I'm being honest about:
| Terrain Slabs caveat | The deal | |
|---|---|---|
| 🔃 | A custom slab placed on top of a vanilla slab | Doesn't lower yet — flip it around (vanilla on terrain) and you're golden ✨ |
| 🗼 | Very tall (3+) combined-slab towers | Cap how far they lower, on purpose — keeps targeting reliable instead of breaking your clicks |
If something looks wrong, it probably is — and it's probably worth reporting (just see if it's already been reported first pleeease). 🐛
Compatibility
- Minecraft 1.21.11
- Fabric + Fabric API
- Singleplayer and server (install on the client for the visuals)
- ✅ Countered's Terrain Slabs — now supported! (optional)
Mods that heavily customize block shapes, rendering, collision, placement, or models may still need dedicated compatibility work.
🐛 Reporting bugs
Bug reports are super duper helpful! The most useful ones include:
- Minecraft, Slabbed, Fabric Loader, and Fabric API versions
- Other installed mods (especially Terrain Slabs!)
- 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
- Custom-slab mixing in both directions, and deeper combined-slab towers
- More supported object categories, added carefully
- Tighter agreement between visuals, outlines, and raycasts
- 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!
