Gaïa's Breath
A Fabric mod that makes the natural world evolve on its own — grass spreads, flowers bloom, trees regenerate, paths form under footsteps, and burned wood can leave behind charcoal. Minecraft’s ecology becomes alive, gradual, and fully configurable.
About this Mod
🌿 Gaia’s Breath
A Fabric mod that makes the natural world evolve on its own.
Grass spreads, flowers sprout, trees regenerate, metal weathers, wood ages — Minecraft’s ecology becomes alive, gradual, and configurable.
🧭 Overview
The world breathes, grows, and heals over time.
Without player input, nature reclaims barren land and balances overgrowth,
creating a living landscape that changes as you explore.
Main Features
- Vegetation propagation: short grass spreads, may become tall grass, and wild flowers can appear.
- Tree renewal: saplings can pop near trees, letting forests naturally expand.
- Natural path formation: player footsteps gradually wear down grass into coarse dirt and dirt paths, which can slowly recover over time.
- Charcoal from burned wood: when wood blocks are burned by fire, they can drop charcoal instead of disappearing completely.
- Fully configurable via an in-game screen (tick budgets, growth chances, moss spread, path erosion, and more).
- Server-friendly: all updates are tick-limited and distributed across chunks to prevent lag spikes.
🌱 Natural Growth
Vegetation Propagation
- Grass blocks may receive short grass over time.
- Short grass can convert to tall grass based on probability.
- Flowers occasionally generate in suitable spots (low density, natural feel).
⚙️ Configuration (ModMenu)
Open the Gaia’s Breath configuration screen from ModMenu to fine-tune every natural mechanic.
All values are stored in config/gaiasbreath.json and can be safely edited in-game or manually.
