Interactive Foliage System: Seasons, SSS & Wind (URP)

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.
