Lucid Water Pro - Ocean / Water + Physics for URP

Lucid Water Pro is a complete AAA water system for the Universal Render Pipeline (URP). It gives you a realistic infinite ocean, lakes, rivers and pools, boat wakes shaped by the real hull, buoyancy, caustics, waterfalls and a seamless underwater view. Everything is simulated on the GPU and fully procedural: no textures, no baked normal maps and no visible tiling, all the way to the horizon. A stylized anime water mode is built in, so the same component covers both photoreal and toon or cel-shaded games. ▶ INFINITE FFT OCEAN • GPU FFT ocean waves (Tessendorf method) driven by a physical JONSWAP wave spectrum, with wind sea and swell • Three wave cascades, from 500 m swells down to small ripples, with no repeating patterns • Physically calibrated wave heights, choppy sharp crests and correct deep- and shallow-water dispersion • A camera-following clipmap mesh gives an endless ocean with no tiling, popping or swimming textures • Bounded mode for lakes, rivers, ponds and swimming pools ▶ REALISTIC WATER SHADING • Physically based GGX sun glitter and specular highlights • Light absorption and scattering (Beer–Lambert) for turquoise shallows that fade into deep blue • Subsurface scattering: sunlight glowing through backlit wave crests • Refraction, depth-based colour and soft shorelines ▶ REFLECTIONS • Planar reflections, with total internal reflection when seen from below • Screen-space reflections, with reflection probes as a fallback ▶ FOAM & CAUSTICS • Whitecaps that form where waves fold and break • Shore foam, contact foam around objects, and wake foam that dissolves into lace • Real-time caustics computed from the simulated waves, on the sea floor and underwater ▶ BOAT WAKES & WATER INTERACTION • A dispersive wave simulation on the GPU: objects push water aside by the real shape of their mesh • Natural Kelvin V-wakes, bow waves, stern troughs and a turbulent slick behind boats • Ripples, rain, splashes and swimmers on the same simulation • Submarines: surfaced hulls push bow waves, submerged ones slip quietly underneath • Clip Water Inside: exact per-pixel removal of water inside open boat hulls ▶ BUOYANCY / FLOATING PHYSICS • Archimedes buoyancy on the real simulated waves, not an approximation • Multi-point floating for boats, relative density, drag and smooth heave damping • A drivable demo boat and submarine controller included ▶ UNDERWATER • Seamless waterline split when the camera crosses the surface • Underwater fog, caustics and volumetric light shafts (god rays) • Snell's window: the sky seen through a circle of light, with the underside mirroring the deep ▶ WATERFALLS & PARTICLES • Procedural waterfalls: ballistic sheets that speed up and aerate as they fall • Plunge-pool churn, spray and mist • Soft, round splash droplets, mist and bubbles (no square particles) ▶ ANIME / STYLIZED WATER • A one-click toon water mode: banded colours, crisp foam lines, cel highlights and sparkles • Suited to anime, cartoon, low-poly and stylized games ▶ PRESETS & WORKFLOW • One-click looks: Open Ocean, Tropical Lagoon, Stormy Sea, Calm Lake, Pool and Anime, from glassy calm to a full gale • Setup Wizard, custom inspectors and debug views • Clear scripting API for wave height queries, splashes and interaction • A full showcase demo scene: island, dock, boat, submarine, waterfall, pool and weather switching Perfect for: open-world, survival, sailing, naval, pirate, fishing, island, underwater exploration, racing boat, flight and stylized anime games, as well as cinematics, architectural visualization and virtual production.
