About this project
What does Beneath the Wetlands add?

Have you ever had nightmares of vast ancient swamps awaiting and calling? And of some machines moving beneath their surface? Gigantic rusty gears, pistons and pipes. Wandering blue lights that lure strangers into the mire. The atrocious amalgam of living metal and rotting plants…
About
Beneath the Wetlands is a Fabric vanilla-style mod created by the Birchfolks team and inspired by a creepypasta. It focuses on expansion of the content related to swamp biomes. The mod adds new mobs, block, items and structures--old mechanisms lurking in the depths of the wetlands. BtW is under active development and more features are to come soon.
Fabric API and GeckoLib are required.
BtW is compatible with generation mods, even with those that add new biomes (for the structures to generate in them, names of these biomes must be written manually in the config file).
Currently BtW supports the following languages:
<center>English | Polish | Russian | Ukrainian | Pre-reform Russian</center>
Since the translations may not be 100% and we aim to add more languages, we seek for community help. If you want to translate the mod into the language you speak, feel free to contact us on Discord.
Features
Mobs

Blocks and Items
- Sapropel Block - generates on the bottom of the swamps, breaks into several pieces of sapropel

FAQ
Q: What creepypasta this mod is based on?
A: It's a short creepypasta from an image board, you can read it translated into English in our Discord.
Q: What versions of Minecraft are supported?
A: Currently 1.19.2 and 1.20.1. We aim to support the newest versions.
Q: Can you downgrade this mod to 1.12.2?
A: No. Downgrading a mod is very tedious and some features might break.
Q: Can you make a Forge version of this mod?
A: Definetely not now or soon. Fabric is much more user- and developer-friendly. But maybe some day.
Q: Why does updating take so long?
A: There're only three of us and modding isn't our job (unfortunately). We do it in our free time.
Q: Can you translate this mod to [language]?
A: No, but maybe you can. If you want to translate the mod into the language you speak, contact us via the dedicated channel in our Discord.
Q: Can the structures of this mod generate in the biomes of other mods?
A: Yes, but for this to happen you need to manually put the names of biomes in the config file. We didn't make the structures generate in any swamp biomes by default in case you wouldn't want BtW to interfere with other mods.
Q: Where can I find the config file?
A: There's a folder in the Minecraft root directory named "config", inside of it you can find "wetlands.json".
