Crest Water 4 HDRP (Ocean, Rivers & Lakes) v4.22.5 is a high-performance water solution designed for Unity, offering a comprehensive and efficient workflow to add realistic water effects in minutes. The resource pack includes three core components: water surface, underwater, and waves, with sane and balanced default settings to reduce setup time. It provides detailed help boxes in the inspector that display validation errors and offer fix buttons to guide users through proper configuration.
Key features include support for Unity 6, a state-of-the-art LOD system delivering class-leading performance, and an innovative "equalizer" style wave authoring system that supports both FFT and Gerstner waves. The "wave spline" technology enables precise control over water simulation, including rivers, lakes, and shorelines. The pack includes simulated light transport with reflection, refraction, scattering, caustics approximation, and shadowing. Underwater effects support partial submersion and meniscus, while GPU and CPU-based water displacement queries enable dynamic interactions.
Additional features include a shifting origin component for large or open worlds, dynamic wave simulation for object-water interactions like boat wakes, shallow water effects with light scattering and wave attenuation, foam generated from waves and shorelines, and the ability to apply surface color like decals. Water volumes can restrict rendering to specific geometries, and flow and surface clipping allow for horizontal motion and carving of hulls or caves. Planar reflections, multiple rendering paths (deferred, forward, perspective, orthographic, stereo), and shader graph support—including Ocean Shader Graph (2021.3+) and shader graph nodes for underwater effects—are included. Screen-space reflections and planar reflection probes are supported, as are decals and integration with Gaia Pro VS.
The asset is compatible with a wide range of other Unity tools and plugins, including Dynamic Water Physics 2 (DWP2), Enviro, Cozy Weather, Buto, Expanse, Gaia, MicroSplat, MicroVerse, Nature Manufacture, Azure[Sky], Skybox Creator, and Vegetation Studio. It comes with several example scenes, including the "Submarine" demo scene created by the Digital Wizards team (Aldana Zanetta and Fernando Zanetta).
