Natural Philosophy Mod (1.21.1) – Richer Plant Life Across Every Vanilla Biome

Natural Philosophy Mod reworks Overworld biome decoration to create believable ecosystems across your world. The mod updates older areas with newer vegetation and blocks without altering the default terrain shape. It fills empty clearings with subtle plant life, lush undergrowth, and diverse micro-environments while preserving the original feel of the game.

Features:

• Reworks Overworld biome vegetation to provide richer sub-biome variation and plant growth.
• Integrates newer blocks and plants into classic biomes that lacked modern detail.
• Keeps default terrain shapes intact while completely refreshing surface decoration.
• Adds rocky cliff details to steep hills and mountain slopes during world generation.
• Fixes cold biomes by generating snow layers and ice under tree canopies.
• Populates ocean floors, swamps, and riverbanks with thick rushbeds, sugarcane, and kelp.
• Supports biome tag customization for cliffs and river sediment across custom world generation.
