Procedural Nature Generator - Trees, Biomes & Environment

Procedural Nature Generator - is a procedural low-poly nature creation system for Unity.

It allows you to generate unique, animated trees and build full biomes using customizable rules, objects, and environment settings — both in the Editor and at runtime.

Whether you're creating a stylized forest, a dynamic world, or complete environments with multiple biome types, this tool gives you full control over vegetation, object distribution, and visual atmosphere.

Key Features:

• Fully procedural low-poly tree generation
• Custom branch and foliage prefab support
• Recursive growth with adjustable depth, scale, and randomness
• Foliage appears on terminal branches for more natural results
• Procedural branch animation (no bones or shaders)
• Full biome system with multiple biome types on one map
• Custom object spawning per biome (trees, rocks, plants, etc.)
• Biome-based lighting, fog, and camera settings
• Biome boundaries with editable areas in the scene
• Works with any surface (plane, mesh, or custom terrain)
• Lightweight and mobile-friendly
• Includes TreeSpawner for runtime placement
• Modular and easy to extend

Ideal For:

• Stylized or minimalist 3D games
• Procedural environments
• Open worlds with multiple biomes
• Mobile and VR projects
• Infinite world generation
• Runtime level decoration

Flexible Parameters:

• Tree depth and branching probability
• Branch rotation and scale randomness
• Foliage scale variation
• Animation speed and amplitude
• Biome object density and spacing
• Biome-specific visual settings

Workflow:

1. Create prefabs for branches and foliage.
2. Add the TreeGenerator component and configure tree settings.
3. Set up BiomesManager and define biome rules and objects.
4. Adjust boundaries and environment settings for each biome.
5. Generate trees or full environments in seconds.

This tool is designed to stay simple and performant, while giving you enough flexibility to create diverse trees and complete biome-based environments.
