Crest Ocean System HDRP v4.17.3 is a technically advanced, feature-rich ocean system designed for PC and console platforms. It offers realistic water simulation with support for simulated light transport, including reflection, refraction, scattering, caustics approximation, and shadows. The system features wave simulation using both FFT and Gerstner methods, with an innovative 'equalizer' style wave authoring approach. Water displacement can be queried via GPU or CPU, and dynamic wave simulation ('ripple sim') enables realistic interactions with objects such as boats and wakes. A 'wave spline' technology provides detailed control over water behavior in rivers, lakes, and shorelines. Shallow water effects include light scattering and wave attenuation. Color can be applied to the ocean surface like decals, with support for HDRP Decals. Foam is generated from waves and shorelines and can be manipulated using mesh, trail, line, and particle renderers. Underwater effects support partial submersion and meniscus, while water volumes can restrict rendering to specific geometries such as spheres. Shader Graph nodes allow underwater effects on transparent objects, and flow enables horizontal water movement. The system includes a physics interface with buoyancy and support for Dynamic Water Physics 2. Flexible time synchronization supports networking and cutscenes, while surface clipping allows for hulls and caves to be carved into the water surface. The package supports Ocean Shader Graph (2021.2 only), Ray-Traced Reflections (2021.2 only), decals, screen-space reflections, VR/XR (multi-pass and single-pass instanced), and both deferred and forward rendering in perspective and orthographic modes. It includes multiple example scenes, real-time validation errors in the Inspector with fix buttons, and online documentation with embedded videos. Note: No support is planned for Unity 2023 or later; a new asset is currently in development.
