Crest Water 4 BIRP (Ocean, Rivers & Lakes) v4.22.3 is a high-performance water system designed for Unity, offering a comprehensive and efficient solution for creating realistic ocean, river, and lake environments. Developed by professional game developers, it is widely trusted by studios for its quality, performance, and reliability, having been implemented in multiple successful games and simulators, and featured in SIGGRAPH talks. The resource pack supports Unity 6 and includes a state-of-the-art LOD system that delivers class-leading performance. It features an innovative "equalizer" style wave authoring system supporting both FFT and Gerstner waves, along with a "wave spline" technology enabling detailed control over water simulations for rivers, lakes, and shorelines. The system includes simulated light transport with reflection, refraction, scattering, caustics, and shadowing, underwater effects with partial submersion and meniscus, and dynamic wave simulation for interactions such as boat wakes. It supports GPU or CPU-based water displacement queries, Unity Server integration for authoritative multiplayer environments, and a shifting origin component for large or open worlds. Additional features include foam simulation from waves and shorelines, surface decal-like coloring, water volume restrictions, flow-based horizontal motion, physics integration with buoyancy and Dynamic Water Physics 2, flexible time synchronization, surface clipping, planar reflections, and support for multiple rendering pipelines including deferred, forward, perspective, orthographic, and stereo (VR/XR). The pack also integrates with Gaia Pro VS and includes example scenes covering various use cases, with real-time validation feedback and embedded video documentation to guide setup and usage. Crest 5 is now available, but Crest 4 continues to receive bug fixes and minor improvements.
