MSS - Moog's Soaring Structure (config pack)

This datapack is automatically kept up to date.

It now stays in sync with the latest version of the mod. Prefer a different approach? You can still build your own config pack from our git repos or use a config mod like Cristel Lib

How To Use This Datapack

This is a template ("config") datapack for my structure mod, Moog's Soaring Structures. Everything MSS generates is data-driven, so this pack lets you re-configure the mod (remove structures, change how rare they are, and control which biomes they spawn in) just by editing JSON files. No coding required.

Step 1: Install the datapack

1. Download the version of this pack that matches your Minecraft version from the Files tab.
2. Add it to your world:
   • One world: drop the downloaded .zip into .minecraft/saves/<your world>/datapacks/.
   • Every world / on a server: use a datapack loader such as Paxi so the pack is applied globally instead of per-world.
3. Enable it in-game: load the world and run /datapack enable "file/<datapack file name>", or run /reload if the pack is already in the folder.

⚠️ Worldgen only affects new chunks. Changes to structure spawning, rarity, or biomes only appear in newly generated terrain. Already-explored chunks won't change. To see your edits, explore into fresh land or start a new world.

Step 2: Edit the pack

1. Open the datapack .zip (or unzip it) and browse to the data/mss/ folder.
2. Edit the JSON file for the thing you want to change (see the common tasks below).
3. Save, re-zip if you unzipped it, then run /reload in-game (or regenerate the world) to apply.

Common things people want to do

Remove a structure completely Open its file in data/mss/worldgen/structure_set/… (each .json is named after the structure it controls) and empty the structures array so nothing spawns:

{
  "structures": [],
  "placement": {
    "type": "mss:advanced_random_spread",
    "salt": 71204863,
    "spacing": 40,
    "separation": 20
  }
}

Make a structure rarer or more common In the same structure_set file, change spacing and separation. Larger spacing means rarer. separation must always be smaller than spacing.

"placement": {
  "type": "mss:advanced_random_spread",
  "salt": 71204863,
  "spacing": 100,
  "separation": 80
}

Change which biomes a structure spawns in Edit the matching tag in data/mss/tags/worldgen/biome/has_structure/… and add or remove entries from values:

{
  "replace": false,
  "values": [
    "#minecraft:is_overworld",
    { "id": "#biomesoplenty:is_overworld", "required": false }
  ]
}

• Plain biomes look like "minecraft:meadow"; biome tags start with #, e.g. "#minecraft:is_overworld".
• Modded biomes/tags must use "required": false so the pack still loads when that mod isn't installed.

The tasks above cover the most common tweaks. Every JSON file in this pack (structures, template pools, placement types, biome tags and the .nbt building blocks) is documented in full on the Moog's Structure Lib Wiki:

The wiki's examples use Moog's Voyager Structures (MVS), but the layout is identical for MSS. Just swap the mvs namespace for mss.
