## What it is
Crest Water 4 is an advanced, class-leading water and ocean rendering system for Unity, implemented in C# with GPU displacement and sampling techniques. It supports the built-in renderer, with paid variants for URP and HDRP, and has been used in shipped games.

## Use cases
- render realistic oceans in a Unity game
- simulate interactive water waves and boat physics
- add buoyancy to ships and floating objects
- create ocean shorelines and foam effects
- build a sailing or water-based game

## When to choose
- you need production-quality water rendering in Unity
- your game features oceans, rivers, or large bodies of water
- you want a battle-tested water system used in shipped titles

## When to avoid
- you are not using Unity
- you need water for a non-game engine or web project
- you require URP/HDRP support without purchasing the paid asset versions

## Facets
- artifact type: library
- maturity: active
- function: simulation, graphics, game-engine
- domain: simulation, graphics
- platform: game-engine, cross-platform
- tags: unity, water-system, ocean, shader, rendering, waves, game-development
