CaveBiome Mod

Author of the CaveBiome Mod: mlie

The CaveBiome Mod adds a new cave biome that lets you explore and settle deep underground tunnel networks, offering a unique subterranean survival experience with custom map generation and integration with several popular mods.

CaveBiome Mod Features

  • Adds a new fully playable cave biome where colonies can be founded deep below the surface.
  • Generates winding tunnels and underground spaces suited for hidden or protected settlements.
  • Updated map generators so cave features can also appear when using DeepRim and Z-Levels.
  • Prevents things from short-circuiting in the rain unless they are built in a cave-well, making underground infrastructure more practical.
  • Includes a French translation (thanks to qux!).
  • Adds a compatibility patch for Vanilla Fishing Expanded so cave content works smoothly alongside fishing mechanics.
  • See the forum thread for a complete changelog, additional details, and related cave-themed mods.

Compatibility notes

  • Load order: Caveworld Flora Mod must be enabled before the CaveBiome Mod or the cave biome will not function correctly.
  • Supports cave map generation with DeepRim and Z-Levels.
  • Includes a dedicated patch for Vanilla Fishing Expanded.
  • If you encounter errors, first test only with the CaveBiome Mod and its required mods active. If the issue disappears, re-enable other mods gradually to find the conflict.
  • Always upload your log using the Log Uploader when requesting support.
  • For best support, use the dedicated Discord channel for error reporting rather than creating Steam discussion threads, since the author does not receive notifications from those.
  • If you discover a fix or workaround, please share it on the GitHub repository.
  • Use RimSort to keep your mod list organized and reduce load-order issues.
