No Caves Mod
Disables caves and canyons based on the configuration, and maintains compatibility with other terrain modification mods and data packs as much as possible.
About this Mod
NoCaves
Disables Noise Caves, Density Function Caves, Generated Features, Carver Caves and Canyons based on the configuration, and maintains compatibility with other terrain modification mods and data packs as much as possible. Affects all biomes and all world generation presets by default.
根据配置禁用噪声洞穴、密度函数洞穴、地物、雕刻器洞穴和峡谷，并尽可能保持与其他地形修改模组和数据包的兼容性。默认影响所有生物群系和所有世界生成预设。
Configuration 配置
The configuration file is located at config/no_caves.json. If the configuration file does not exist or is corrupted, a new one will be generated. If the configuration file is incomplete, a new one will be generated by merging the existing values with the default values.
配置文件位于config/no_caves.json。如果配置文件不存在或损坏，会重新生成一份。如果配置文件不完整，会合并已有值和默认值并重新生成一份。

noiseCavePatterns |
List of regular expressions | The names of the noise caves to filter. 要过滤的噪声洞穴名称。 |
enableDensityFunctionCaveFilter |
Boolean, default = true |
Set to true to enable density function cave filter, which filters references to other cave density functions in the density function (including the final density).设置为 true以启用密度函数洞穴过滤器，在密度函数（包括最终密度）中过滤对其他洞穴密度函数的引用。 |
densityFunctionCavePatterns |
List of regular expressions | The names of the density function caves to filter. 要过滤的密度函数洞穴名称。 |
Glossary 词汇表
- carvers: are referenced in biome definitions (
worldgen/biome), used to add caves and canyons. - density functions: are referenced from the noise router in noise settings (
worldgen/noise_settings), make up mathematical expressions to obtain a number from a position. - final density: a part of a dimension's noise settings (
worldgen/noise_settings), is the main density function that determines whether a block position should be solid or air.
- 雕刻器：在生物群系定义（
worldgen/biome）中引用，用于添加洞穴和峡谷。 - 密度函数：主要供噪声设置（
worldgen/noise_settings）使用，可以根据一定的运算法则将一个坐标转换为一个数。 - 最终密度：是噪声设置（
worldgen/noise_settings）的一部分，是决定方块位置应为固体还是空气的主要密度函数。

No Caves Mod server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.
Is No Caves Mod compatible with fabric and forge and neoforge?
No Caves Mod officially supports fabric, forge, neoforge for Minecraft 26.1.2, 26.1.1, 26.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with No Caves Mod – how to optimize performance?
Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if No Caves Mod consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
