Natural Philosophy
Natural Philosophy changes how biomes are decorated across the Overworld, adding vegetation, sub-biome variation and object permanence that vanilla biome design lacks.
What it does
Natural Philosophy focuses on biome decoration rather than terrain. The terrain profile stays at the Minecraft default, and the mod works by replacing vegetation features in most biomes, along with commonly modified features, so that each biome gains detail and sub-biome variety. It aims to represent developed ecosystems accurately, extending Minecraft's ideas instead of discarding them, and it integrates newer blocks and features into older biome styles. It requires Lithostitched, which must be installed alongside it on NeoForge.
Players see the result as a fuller Overworld biome overhaul, and the mod is built around the idea that most vanilla biome decoration is sparse. Modded biomes are grouped inside the mod by cliff and sediment tags, and the mod carries widely applicable changes for riparian areas, sediment and cliffs. A deeper ocean setting is suggested for a more natural look. Servers that run it need every player to install it too. Files are available for 1.20.4 and 1.21.1, and the latest NeoForge build, 4.1.0 for 1.21.1, was published on 2026-08-30. The source code is open, under the MIT License.
Key features
Sub-biome variation
Biomes gain sub-biome variety, so areas of the same type look less uniform across the map.
Vegetation replacement
Most biomes receive new vegetation features in place of the defaults, including flower meadows and oak trees.
Tag-based biome sorting
Modded biomes are grouped by tags for cliffs and sediment, so their placement can be controlled by datapack authors.
Terrain left unchanged
Terrain generation stays at the Minecraft default, so the change is limited to decoration.

What the author says
Natural Philosophy replaces and overhauls Minecraft biome decoration, integrating newer blocks and features into older biomes while keeping some of the essence of Minecraft biome decoration. It extends upon Minecraft's ideas without entirely supplanting or replacing them, while integrating new content and new biome…
