Prefer a different approach? You can still build your own config pack from our git repos or use a config mod like [Cristel Lib](https://modrinth.com/mod/cristel-lib) Feedback Please comment any ideas you may have to improve this mod. Any and all feedback is greatly appreciated :) Additionally, if you make any configs you think other people would enjoy, send it to me on Discord and I'll be happy to upload it here! NeoForge and Fabric All datapack versions work on Forge, NeoForge **and** Fabric. How To Use This Datapack This is a template ("config") datapack for my structure mod, **Moog's Voyager Structures**. Everything MVS 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 **Versions** tab above. 2. **Add it to your world:** - **One world:** drop the downloaded `.zip` into `.minecraft/saves/ /datapacks/`. - **Every world / on a server:** use a datapack loader such as [Paxi](https://modrinth.com/mod/paxi) so the pack is applied globally instead of per-world. 3. **Enable it in-game:** load the world and run `/datapack enable "file/ "`, 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/mvs/` 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/mvs/worldgen/structure_set/…` and empty the `structures` array so nothing spawns: ```json { "structures": [], "placement": { "type": "mvs:advanced_random_spread", "salt": 836845261, "spacing": 77, "separation": 58 } } ``` Example file: `data/mvs/worldgen/structure_set/other_decoration/crimson_enchanting_table.json` **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`. ```json "placement": { "type": "mvs:advanced_random_spread", "salt": 836845261, "spacing": 100, "separation": 80 } ``` **Change which biomes a structure spawns in** Edit the matching tag in `data/mvs/tags/worldgen/biome/has_structure/…` and add or remove entries from `values`: ```json { "replace": true, "values": [ "minecraft:snowy_taiga", { "id": "byg:frosted_taiga", "required": false } ] } ``` - Plain biomes look like `"minecraft:snowy_taiga"`; biome tags start with `#`, e.g. `"#minecraft:is_taiga"`. - **Modded** biomes/tags must use `"required": false` so the pack still loads when that mod isn't installed. Full Per-File Customisation Reference 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**: 📖 **[Moog's Structure Lib Wiki »](https://github.com/FinnSetchell/MoogsStructureLib/wiki)** | What you want to edit | Wiki page | | --- | --- | | Where structures spawn (spacing, salt, biomes) | [Structure Sets](https://github.com/FinnSetchell/MoogsStructureLib/wiki/Structure-Sets) | | A structure's type & properties | [Structure Files](https://github.com/FinnSetchell/MoogsStructureLib/wiki/Structure-Files) | | Which building pieces are used | [Template Pools](https://github.com/FinnSetchell/MoogsStructureLib/wiki/Template-Pools) | | Advanced placement & terrain adaptation | [Placement Systems](https://github.com/FinnSetchell/MoogsStructureLib/wiki/Placement-Systems) | | The `.nbt` structure files themselves | [NBT Files](https://github.com/FinnSetchell/MoogsStructureLib/wiki/NBT-Files) | | New to all of this? | [Getting Started](https://github.com/FinnSetchell/MoogsStructureLib/wiki/Getting-Started) | The wiki's examples are built around Moog's Voyager Structures (MVS), so they apply directly to this pack. ***  The best and fastest way to get
FreeMinecraftMods decision guide
This mod is most relevant to players looking for adventure, management, worldgen on datapack, fabric. Treat those labels as discovery hints, then verify the exact file and dependency list on the official project page.
The source record was updated on Jul 6, 2026, which is a recent freshness signal. A recent date does not guarantee support for every loader or Minecraft version, so still inspect the current file list.
What to verify before choosing a file
- Confirm that the file is published by the credited creator on the linked official source.
- Match the Minecraft version exactly instead of relying only on a broad category label.
- Read dependencies, incompatibilities, and changelog notes before updating an existing instance.
- Match the loader or server platform and its required version. Forge and NeoForge are not interchangeable.
- Back up worlds and configuration files before testing the project in a long-term save or public server.
