The Interactive Foliage System is a production-ready vegetation framework built for Unity 6 (URP) holding all the Industry-level features wrapped in this single package that provides you;
🍂1. Dynamic Seasons & Procedural Snow
- Season Interpolation: Seamlessly interpolate across a full summer, autumn, and winter cycle using a linear master slider for mathematically fluid, physically realistic state transitions.
- Angle-Aware Snow Accumulation: Features an advanced Dot(World_Normal, Up_Vector) shader mask that procedurally blends snow layer on top-facing surfaces without stretching textures, leaving vertical undersides completely clear to make it physically accurate.
☀️2. Next-Gen Subsurface Scattering (SSS)
- Translucent Leaf Rendering: Simulates realistic light bleed, subsurface diffusion, and backlighting through alpha-clipped foliage geometry under directional light projection.
- View-Dependent Light Scattering: Real-time mathematical calculation that dynamically scales translucency based on the light source angle and camera view-direction, integrating perfectly with dynamic sun rotation.
⚔️3. High-Fidelity Interactivity (Trample/Bend & Slice)
- Vertex-Based Deformation: Realtime foliage bending and trample deformation when interacting with characters, enemies, or projectiles, returning smoothly to rest position via vertex shader math.
- Runtime Geometry Slicing: Supports dynamic leaf slice, harvesting, or clearing mechanics by manipulating vertex visibility directly within the shader graph using runtime collision data.
🍃4. Realistic Organic Wind Engine
- Non-Repeating Wind Patterns: Completely replace boring, repetitive sine-wave animation by using multi-octave world space noise for natural wind simulation according to your preferred wind direction and frequency.
- Dual-Frequency Animation: Separates low-frequency trunk sways from high-frequency leaf flutters via vertex color masks to ensure realistic, asynchronous movement.
🔆5. AAA Custom Lighting & Normal Correction
- Spherical Normal Overrides: Resolves directional light projection errors and pitch-black shading artifacts commonly seen on many leaf mesh surfaces by overriding mesh normals with a spherical orientation to ensure physically correct shading on any tree models.
- Unity 6 Forward+ Integration: Fully compatible with the modern Forward+ pipeline, ensuring your custom normal data correctly samples real-time ambient lighting, light probes, and shadow cascades.
⚡6. Production-Ready Performance Optimization
- GPU Resident Drawer Compatible: Fully compliant with Unity 6’s GPU Resident Drawer, BatchRendererGroup and SRP batcher allowing you to draw thousands of dense foliage instances with near-zero CPU overhead.
- Vertex-Stage Math Isolation: Offloads all complex wind, seasonal interpolation, and player interaction math entirely to the Vertex Shader stage, keeping the Fragment pipeline clear and frame rates stabilized.
Plug-and-Play Integration: Everything you need—including C# controllers, optimized shadergraphs, and material presets—is fully pre-configured and ready to drag and drop directly into your scene.
This system is also fully integrated and compatible with Realistic Trees & Foliage Bundle (Mobile Optimized) giving you more 3D models readily optimized for any project.
