Hello there, unfortunately, according to the fact that many promising realistic water systems for Unity, which I have bought (and spent a lot of money on), are deprecated one by one, I have decided to develop my own. (hoping to finish my game someday, which makes strong use of water simulations) A prototype already exists (not yet in Unity and also without shaders, but first I was only interested in the wave motion). This water system is programmed with Processing (Java) and is based on a modified Phillips Spectrum for more control over the waves and their direction. The example uses my own FFT routine that has not yet been heavily optimized at this moment. Here is a Youtube link: You are welcome to write me what you think about it. The next planned steps are the implementation in Unity with shaders. Many Thanks.
