KWS2 Dynamic Water System

Before updating, REMOVE the water shaders/scripts folder. KWS2 is an advanced water system for Unity, built around a physically-based real-time simulation. Unlike many static or purely visual solutions, KWS2 simulates actual wave-based flow, interactions with dynamic objects, and terrain-driven behavior. Fully customizable through zones and optimized as far as technically possible for large-scale water environments, with support for natural scenarios like calm-to-moderate oceans, small waterfalls, and realistic river flows. Ideal for projects requiring believable, performance-friendly water, from open seas to mountain streams, without targeting exaggerated extremes :) Compared to the first version KWS Water System, some outdated features have been removed, while others have been significantly improved and reworked from the ground up. KWS2 is a completely separate asset and does not require KWS1 to work. An upgrade discount (~40%) is available for existing KWS1 users. Supported pipelines: Built-in, URP, HDRP, Unity 6+, including modern RenderGraph-based versions Mobile platforms are not supported due to compute shader limitations and heavy real-time rendering features. In future updates, lighter baked alternatives (such as precomputed simulation or ocean data) are planned, which should allow limited support on mobile hardware, webGPU, etc. Other platforms (VR, Metal, PlayStation, Xbox, etc.) may work, but are not officially supported or guaranteed. You can find additional technical information in the online README which is continuously being updated and expanded. Also you can find an interactive PC DEMO here Main Features Dynamic Water Simulation - Real-time dynamic water simulation using shallow-water equations and FFT ocean rendering - Dynamic wave propagation and water mass movement - Automatic interaction with terrain, obstacles, shorelines, and dynamic objects - Water sources, drains, forces, flow redirection, and configurable zone effectors - Persistent water accumulation, flooding, puddles, and evaporation - Adjustable flow speed, turbulence, wave response, and stability - Quality and performance controls for individual simulation zones - Support for calm water, rivers, shorelines, pools, flooding, and other scenarios - Optional cached simulation for faster and more predictable startup - Dynamic rerouting when obstacles or water sources change Rivers and Waterfalls - Spline-free river creation (no manual river path placement required) - Water automatically follows the terrain - Create flowing rivers using zones, sources, forces, and obstacles - Natural flow redirection around rocks and other geometry - Support for long rivers built from multiple simulation zones - Transfer of incoming water between connected zones - Waterfall rendering with flow, foam, splashes, particles, and wetness Rain, Puddles, and Flooding - Rain can physically add water to simulation zones - Natural puddle formation based on terrain depth - Persistent water accumulation and flooding - Configurable evaporation - Independent rain control for different water areas - Concentric raindrop ripples on water surfaces - Wetness effects around flooded or rainy areas Object Interaction - Interaction with moving and rotating objects - Shoreline response from ocean waves - Water flow redirection around obstacles - Dynamic wave generation from objects - Water displacement and local flow changes - Configurable water source, force, and drain effectors - Custom water source color (blood, oil, etc) - Splash/foam particles generation from surface impacts - Projectile and bullet impact effects Buoyancy - Built-in buoyancy system - Water height, flow and velocity sampling - Suitable for boats, debris, characters, and other floating objects - Public API for custom buoyancy and gameplay systems - Support for both ocean waves and locally simulated water Rendering and Lighting Physically Based Water Rendering - Physically-based lighti
