Terrain Slabs Configured
by Lon4th
Terrain Slabs Configured changes which slabs generate in the world, through a config file, for servers that run Countered's Terrain Slabs.
What it does
The addon sets the terrain slab generation on a server. It can remove listed slabs from worldgen and switch off the listed top blocks that carry them, while the default settings keep the Terrain Slabs snow slab and the vanilla snow block. Its new settings are written to a config file, so a server owner can choose which slabs appear without editing the original mod.
Slabs are placed in a top layer modification step, the same worldgen step the original mod uses for slab placement. Underground ore placement is also listed per biome. Custom slabs from other mods can be registered by pairing a base block with its matching slab, and the defaults already pair Darker Depths' aridrock with an aridrock slab and provide compatibility with Geophilic's rework through the stony shore biome.
Installation needs Forge and Countered's Terrain Slabs, which is required. The server is the side that needs this addon, while clients may leave it out. Files are published for Forge across six game versions, 1.20.1 – 1.20.6, and the mod is released under the MIT License without being open source.

How it compares
Mod Blacklist is server-side only, runs on Forge for 1.18.2, is released under CC-BY-1.0 and is not open source, so it covers a different job from slab generation. Countered's Floating Tree Decay is needed on the server, with the client optional, across Fabric, Forge and NeoForge for 1.20.1 – 26.1.2 under the MIT License, and it is not open source. SnowCrafting is open source under the Apache License 2.0 and needs the server, with clients optional, across 1.21 – 1.21.11 on four loaders.
