GPU-accelerated URP water with waves, refraction, foam, and underwater effects. Easy to use and fully documented!📘 Documentation 🕹️ Compatibility 💬 Support (support@eugatnomstudios.com)A license for this asset guarantees access to updates for Unity 2022-2023 & Unity 6.0–6.3 and future improvements within the Tidal product line.What is Tidal?Tidal is a GPU-accelerated water system for Unity URP, built around FFT-based wave simulation, clipmapped ocean meshes, and modular subsystems. It is designed for oceans, lakes, pools, and large-scale water bodies, with a strong focus on performance, flexibility, and editor tooling.Tidal is intended for developers who want real control over wave behavior, performance scaling, and runtime interaction, rather than a one-size-fits-all water shader.🌊 HighlightsFFT-based multi-cascade wave simulation (GPU compute)Profile-driven wave behavior (wind, fetch, swell, direction)Infinite oceans and bounded lakesGPU height readback for buoyancy & gameplayOptional planar reflectionsUnderwater rendering & depth fogZone-based damping and transitionsExtensive editor tooling and validation🏄 Quick OverviewTidal separates simulation, rendering, and interaction into clear components:TidalCompute - FFT wave simulation (can be shared across bodies)TidalBody - Rendering, mesh LODs, subsystemsTidalSurface Material - Visual appearanceTidalProfile - FFT water settings (as Scriptable Object)Zones & Volumes - Damping, masking, clipping, and interaction controlThis modular design allows multiple water bodies to share a single simulation for excellent performance scalability.💧 Rendering & Visual FeaturesFFT-based displacement with 3 cascadesShoreline & surface foamSubsurface scatteringEnvironment reflectionsOptional planar reflectionsUnderwater fog & lighting syncOrthographic camera supportDay/night & emissive reflection support📦 Demo scenes/contentExtreme wave / tsunami sceneLarge-scale oceans and island sceneIndoor & confined water sceneMulti-body sceneOrthographic camera scenePerformance-focused configuration sceneExample profiles & materialsEditor validation and setup helpers✔️ Platform SupportFully Supported:Windows (DX11 / DX12) - Primary development and tested platformMay Work: (Untested / Limited)macOSiOS / AndroidConsolesVRNot Supported:WebGL - Compute shaders required⚡ PerformanceTidal is designed to scale:Share one simulation across many bodiesReduce FFT resolutionLower simulation update rateDisable planar reflections or underwater renderingAdjust mesh LOD densityFrom calm lakes to massive oceans, performance is always under your control.📘 DocumentationFull setup guides, inspector references, performance tips, and demos:https://eugatnomstudios.com/tidal/doc/Third-Party ContentThis asset includes third-party components licensed under permissive open licenses:Assets from Poly Haven and AmbientCG, licensed under Creative Commons CC0 1.0 Universal3D models by Kenney, licensed under Creative Commons CC0 1.0 UniversalCode and mathematical techniques derived from FFT-Ocean by Ivan Pensionerov, licensed under the MIT LicensePromotional Media Notice:Some promotional screenshots on the Asset Store page use a skybox from the Fantasy Skybox FREE package by Render Knight.
