Crest Water 4 URP (Ocean, Rivers & Lakes) v4.22.3 (01 Feb 2026) is a high-performance water system designed for Unity with URP support. It supports engine versions 2020.3.48 or higher. The system offers a streamlined workflow with three core components: water surface, underwater, and waves. It features sane and balanced defaults, example scenes for various use cases, and real-time validation feedback in the inspector with fix buttons. Comprehensive online documentation includes embedded videos. Key features include a state-of-the-art LOD system for optimal performance, innovative wave authoring with both FFT and Gerstner waves, input-based modification of ocean data using mesh, trail, line, and particle renderers, wave spline technology for detailed control over rivers, lakes, and shorelines, simulated light transport (reflection, refraction, scattering, caustics, and shadowing), underwater effects with partial submersion and meniscus, GPU or CPU-based water displacement queries, Unity Server support for authoritative servers (e.g., MMOs), a shifting origin component for large or open worlds, dynamic wave simulation for object-water interactions (e.g., boat wakes), shallow water effects with light scattering and wave attenuation, foam generated from waves and shorelines, surface color application similar to decals, water volumes that restrict rendering to specific geometries (e.g., spherical water), flow for horizontal surface motion, physics integration with buoyancy and support for Dynamic Water Physics 2, flexible time synchronization for networking and cutscenes, surface clipping to carve out hulls or caves, planar reflections, and support for deferred, forward, perspective, orthographic, and stereo (VR/XR) rendering. Shader Graph nodes allow underwater effects on transparent objects, with Forward+ rendering support. The system has been widely adopted by studios for its quality and performance and has been featured in several successful games and simulators, as well as in SIGGRAPH talks.
