Countered's Terrain Slabs

by Countered

Countered's Terrain Slabs smooths the ground of generated worlds by placing custom slabs along the terrain, so players can walk up slopes without hitting blocky steps.

FabricForgeNeoForgeClient and serverMIT LicenseOpen source1.20.1 – 26.3

What it does

Slabs are generated throughout each chunk, on the surface and inside caves, which changes how underground areas feel to walk through. The mod is built on Architectury API and MidnightLib, both required, and its config lets a player turn slab generation off in the world, leaving only the slabs if that is the setup they want.

The mod targets worlds that keep vanilla terrain shapes while easing the transitions between block heights. Grass, snow and other vegetation can grow on top of the slabs, and blocks can be placed on them. Breaking a slab drops the block it was made from, so no separate slab item is added to the inventory. Files are published for Fabric, Forge and NeoForge across 10 release versions, under the MIT License. The code is open source.

Compatibility is covered for Biomes O' Plenty and Vibrant Journeys. Terrain Slabs Configured requires this mod. The included resource pack partly fixes a grass display issue that some players see with other mods installed.

Key features

  1. Ground and ceiling slabs

    Slabs appear on the surface and within caves, so underground terrain gets the same smoothing as the land above.

  2. Drops the source block

    Broken slabs return the block they were made from, keeping the inventory free of extra slab items.

  3. Toggleable generation

    A MidnightLib config option turns slab generation on or off in a world.

  4. Vegetation on slabs

    Vegetation and snow can generate on top of the slabs, and players can place blocks on them.

Questions

Does Countered's Terrain Slabs need Architectury API?

Yes. Architectury API and MidnightLib are both required, so both must be installed alongside the mod.

Does the mod have to be installed on the server?

Yes. Installation covers the server and each player's game.

Can slab generation be turned off?

Yes. The config, provided through MidnightLib, toggles slab generation in the world, and slabs can be left out if only the other features are wanted.

Is updating an existing world safe?

Not across every version. Moving a world from an older release into the 3.x line removes the slabs generated earlier, so check the project's warning before updating.
