TreeGen is a procedural tree generator for Unity that transforms vegetation creation from time-consuming manual modeling into an automated, algorithmic process. It generates unique, high-quality tree meshes directly in the editor, eliminating the need for external 3D software and pre-made tree assets.
Procedural Tree Generation
At its core, TreeGen generates trees completely procedurally using advanced algorithms. Every tree is unique, created from mathematical rules that control trunk structure, branch distribution, leaf density, and overall form.
- Algorithmic Generation — Advanced procedural algorithms create naturally-looking trees with realistic branching patterns and proportions
- Infinite Variation — Generate unlimited unique tree variations by adjusting generation parameters
- No External Dependencies — Create complete tree models entirely within Unity without external 3D software
Mesh Quality & Performance
TreeGen generates high-quality optimized meshes suitable for production games. The algorithm produces clean geometry with proper topology for rendering, animation, and physics integration.
- Production-Ready Meshes — Generate game-ready tree models with optimized polygon counts
- Mobile Compatible — Works perfectly fine on mobile platforms with efficient mesh generation
- Flexible LOD Support — Create multiple levels of detail for performance optimization across platforms
Customizable Parameters
Full control over tree generation through intuitive parameters. Adjust trunk thickness, branch angles, leaf coverage, tree height, and countless other properties to create exactly the trees you need.
- Branching Control — Adjust how trees branch, split, and distribute limbs
- Foliage Customization — Control leaf density, shape, and distribution
- Trunk & Limb Configuration — Fine-tune thickness, tapering, and structural properties
Rendering Pipeline Support
TreeGen works seamlessly with modern Unity rendering systems:
- Built-in Render Pipeline — Full compatibility with standard Unity rendering
- Universal Render Pipeline (URP) — Optimized for mobile, web, and console platforms
- Cross-Platform Ready — Works across all major platforms including mobile devices
Asset Caching & Workflow
TreeGen excels at pre-generating and caching tree variations for use throughout your project. Generate once, use everywhere—perfect for production pipelines where performance is critical.
