TerraTuner

TerraTuner adds an in-game world creation interface for building highly customized Overworlds without manually editing data packs or world-generation JSON files. Choose a terrain family, adjust its parameters, and create worlds ranging from enormous underground caverns to isolated floating islands and chaotic broken continents.

Terrain types

Caves

Create a connected underground world and control cave size, tunnel width, and cave density. The Giant Cavern variant creates a sealed hollow world with a bedrock floor and roof, uneven aquifers, enormous chambers, stalactites, stalagmites, and towering formations.

Floating Islands

Generate separated islands suspended above the void. Adjust island spacing, thickness, and vertical placement to create anything from small scattered island groups to large floating landmasses.

Chaos World

Generate spectacular broken and hollow continents, dramatic terrain walls, deep lowlands, and unusual large-scale landforms. Continent scale, land ratio, and terrain relief are configurable.

World controls

• Set the Overworld bottom from Y=-992 to Y=-64.
• Set the world ceiling from Y=320 to Y=2032.
• Use automatic or manual sea level.
• Scale terrain horizontally.
• Adjust horizontal and vertical noise-cell sizes.
• Start from the Default, Large Biomes, or Amplified vanilla noise foundation.
• Stretch vanilla terrain vertically through the custom world height.
• Enable or disable aquifers and large ore veins.
• Use the included English or Simplified Chinese interface.

How to use

1. Install Fabric Loader and Fabric API.
2. Place TerraTuner in the mods folder.
3. Open the Create New World screen.
4. Select Custom World Generation as the world type and choose Customize.
5. Select a terrain type, adjust the settings, and click Apply Custom Generation.
6. Finish creating the world normally.

Requirements

• Minecraft Java Edition 1.21.11
• Fabric Loader 0.18.6 or newer
• Fabric API
• Java 21 or newer

Compatibility and important notes

• TerraTuner changes the Overworld generator and is intended for newly created worlds.
• Settings are selected during world creation; the mod does not provide an in-game editor for changing an existing world's generator later.
• Only noise-based Overworld presets are supported.
• Very tall worlds require substantially more generation time, memory, and disk space.
• Back up important worlds before updating the mod or changing a modpack.
• Keep TerraTuner installed when reopening a world created with its custom generator.
• For a dedicated multiplayer world, install the same mod version on both the server and connecting clients. Create and configure the world through the client world-creation screen before transferring it to the server if necessary.
• The mod changes newly generated terrain; already generated chunks are not regenerated.

Modpack permission

You may include TerraTuner in CurseForge modpacks in accordance with the project license. Please link to this project page rather than redistributing the JAR through an external download.

Support

Please report problems in the CurseForge comments and include the Minecraft version, Fabric Loader version, Fabric API version, mod list, and relevant log or crash report. Always back up the affected world before testing fixes.

中文说明

TerraTuner 在创建世界界面中加入可视化的主世界生成设置，不需要手动编写数据包或世界生成 JSON。你可以选择地形类型并调节参数，生成巨型地下溶洞、悬空浮岛或破碎而高耸的混沌大陆。

地形类型

• 洞穴： 调节洞穴大小、洞道宽度和洞穴密度；巨型溶洞模式会生成基岩封顶封底的空心世界、地下水、钟乳石、石笋和巨型岩柱。
• 浮岛： 调节浮岛间距、厚度和高度，生成分散的小型岛群或更宽广的悬浮陆地。
• 混沌世界： 调节大陆尺度、陆地占比和地形起伏，生成断裂中空的大陆、深谷和超长地形高墙。

通用设置

• 世界下界可设为 Y=-992 至 Y=-64。
• 世界顶边可设为 Y=320 至 Y=2032。
• 支持自动或手动海平面。
• 支持水平地形缩放、水平与垂直噪声单元调节。
• 可选择默认、超大生物群系或放大化作为原版噪声基础。
• 可开关纵向地形拉伸、地下含水层和大型矿脉。
• 内置英文和简体中文界面。

使用方法

安装 Fabric Loader、Fabric API 和本模组，在“创建新的世界”界面选择 自定义世界生成，点击“自定义”，选择地形并调节参数，最后点击 应用自定义生成。

本模组目前仅支持 Minecraft Java 版 1.21.11、Fabric 和 Java 21。极高的世界会明显增加生成耗时、内存和存档占用。使用或更新模组前请备份世界，并且不要从使用自定义生成器的存档中移除本模组。
