Crest Water 4 BIRP (Ocean, Rivers & Lakes) v4.22.3 (01 Feb 2026) is a powerful and reliable water system designed for Unity 6, offering a comprehensive solution for creating realistic ocean, river, and lake environments. The resource pack enables developers to add water in minutes through three core components: water surface, underwater, and waves. It features sane and balanced defaults, with multiple example scenes covering a wide range of use cases. Detailed help boxes in the inspector display validation errors and include fix buttons to guide proper setup. Online documentation includes embedded videos for easier learning.
Key features include a state-of-the-art LOD system for optimal performance, an innovative "equalizer" style wave authoring system supporting both FFT and Gerstner waves, and a "wave spline" technology that provides detailed control over water simulations, including rivers, lakes, and shorelines. The system simulates light transport with reflection, refraction, scattering, caustics, and shadowing. It includes underwater effects with partial submersion and meniscus, GPU or CPU-based water displacement queries, and Unity Server support for authoritative servers such as MMOs. A Shifting Origin component supports large or open worlds, while dynamic wave simulation enables realistic interactions like boat wakes. Shallow water effects include light scattering and wave attenuation, with foam generated from waves and shorelines. Color can be applied to the ocean surface like decals, and water volumes allow rendering restrictions to specific geometries. Flow enables horizontal water surface motion, and a physics interface supports buoyancy and Dynamic Water Physics 2. Flexible time synchronization supports networking and cutscenes, surface clipping allows carving of hulls or caves, and planar reflections are supported. The system works with deferred, forward, perspective, orthographic, and stereo (VR/XR) rendering, and integrates with Gaia Pro VS. This version continues to be supported with bug fixes and minor improvements, while Crest 5 is now available.
