About this Mod
TFC Structure Compat is an expanded fork of claustra01's TFC x YUNG's Better Series, extended to support a much wider range of structure mods for TerraFirmaCraft 1.21.1 on NeoForge. All credit for the original mod, core mixin system, and TFC block replacement processor goes to claustra01. This version builds on that foundation with additional structure mod support, TFC-appropriate loot tables, and terrain adaptation fixes.
What this mod does: Structures from supported mods will now spawn correctly in TFC biomes, use proper terrain placement so they don't float above the ground, and contain TFC-appropriate loot in their chests instead of vanilla items.
Installation
Always required (client and server / singleplayer):
- TerraFirmaCraft
- YUNG's API (if using any YUNG's mod)
- Moog's Structure Lib (if using MVS, MTR, or MMV)
Optional — install whichever you want:
- YUNG's Better Dungeons / Strongholds / Mineshafts / Ocean Monuments / Nether Fortresses
- Moog's Voyager Structures / Temples Reimagined / Missing Villages
- Towns and Towers + Cloth Config + Cristel Lib
💡 Singleplayer players: We strongly recommend installing all required and optional mods listed above. In singleplayer, your game acts as both client and server if a structure mod isn't installed locally; its structures simply won't load or generate in your world at all.
💡 Multiplayer note: Clients connecting to a dedicated server do not need the structure mods installed; only the server does.
⚠️ The new world requires existing worlds not to get the new structure spawns.
