Unnatural Geophobia - Biome Overhaul

by knishle

Unnatural Geophobia - Biome Overhaul reshapes the vegetation of most overworld biomes, changing where trees, ferns, flowers and boulders appear without altering terrain shape.

What it does

Vegetation layouts across the overworld are rebuilt: dense taiga stands, rose-covered clearings in dark forest, and tundra dotted with trees replace many vanilla forests. Trees, plant life and soil types are changed in many places, with podzol on forest floors, ferns under dark oak trees, pitcher plants in jungle clearings and deepslate boulders scattered over snowy plains. Flower distribution follows real-world patterns as closely as practical, so some biomes gain many more flowers while a handful of others offer very few.

The mod works through surface features only. It replaces naturally generated trees with custom ones, changes sapling-grown trees, and alters ore generation, lava lakes and springs, while leaving the terrain shape alone. It requires only vanilla datapack technology, so no additional mods are needed. It is a server-side mod: the server needs it, and players may add it on the client to see the changes, though joining players do not have to. Files cover 1.20 – 1.21.1 for Fabric, Forge, NeoForge and Quilt, with the latest build 2.0.0+mod for 1.21.1, and the mod is released under All rights reserved, so it is not open source.

Key features

  1. Rebuilt vegetation

    Forests, plains and taiga receive new tree, fern and flower layouts that replace the usual vanilla arrangement.

  2. Custom trees and saplings

    Naturally generated trees are swapped for custom ones, and trees grown from saplings follow the same changes.

  3. Forest fires

    Extreme forest fires can destroy dense, branchy trees, which affects how forested areas recover over time.

  4. Ore and fluid changes

    Underground ore generation, lava lakes and springs are modified, and most forested biomes are kept clear of them.
