Dynamic Rain & Wetness System: Rivulets, Ripples, Interaction [URP]

Bring your world to life with physically accurate weather system. Dynamic Rain & Wetness System is a premium, drag and drop system that instantly applies realistic rain ripples, flowing water, accumulating puddles and interaction to your existing materials seamlessly Whether you are building a gritty cyberpunk city, a lush forest, or a realistic architectural visualization, this shader adapts to your environment seamlessly.

Key Features:

• Procedural Water Ripples: Infinite, non-repeating rain impacts generated entirely procedurally without relying on heavy flipbooks. Ripples dynamically overlap, fade, and react physically, rendering exclusively within flooded puddle zones for maximum realism.
• Flowing Rain Streaks & Splashes: Utilizing smart triplanar world-space projection, rain streaks intelligently slide down vertical faces. Rotate or scale your objects, and the gravity-driven droplets adapt instantly, featuring customizable noise distortion for authentic liquid refraction.
• Dynamic Puddles & Water Runoff: Advanced noise-driven puddle accumulation. Watch as the environment gets soaked—once the puddles hit their flood threshold, the shader triggers a customized directional runoff system to mimic real-world drainage and overflowing water.
• Interactive Wetness & Trails: Built-in support for character and physics interactions. Feed a dynamic Render Texture into the material to part the water, leaving dry trails, splashing footsteps, and localized surface disruption as actors move through the weather.
• Seamless PBR Integration: The shader accurately modifies your base material data—lowering roughness for a glossy finish and darkening the albedo to ensure your surfaces look genuinely wet under dynamic scene lighting.
• Unity 6 URP Ready: Developed natively within the latest Shader Graph framework. Highly optimized, SRP Batcher compatible, and completely artist-friendly with a clean, node-by-node exposed material inspector.
