A Reddit user known as Ok_Art_2784 shared a Gerstner water system they eventually plan to turn into an asset, though the main purpose of the project is to learn and experiment. It's built in URP, reportedly running at around 300 FPS on an RTX 5060.

Here, the developer added tessellation for an almost infinite ocean, improved wave distribution for more realistic behavior, and placed a cargo ship for scale. Buoyancy is still in progress, but SSR is now working. Foam rendering has also been improved with cascades for distant visibility, with particles still in development.

If you're interested in getting started with projects like this, the developer recommends reading The Unity Shaders Bible and watching YouTubers like Acerola and Sebastian Lague. Shaders are, for the most part, all about math.

For those particularly interested in water, Fabrizio Espindola recently announced a new course on real-time water in Unity, covering everything from simple splashes to large-scale ocean systems:

Have a look at Sakura Rabbit's URP mobile water and her water cross-section. Also, you can purchase Eugatnom Studios' Tidal, which is built around FFT-based wave simulation.
