Thank you! I'm a bit busy with life right now, but I'll keep it in mind for the future! |

What would be needed in order to make the foam higher resolution and add better particle effects to this? I'm curious if godot would be capable of providing an ocean close to the same level as sea of thieves and I would like to help get it there but I'm still a beginner with shaders and game dev in general. Edit: I also wanted to add that this already looks fantastic compared to other oceans I've seen in godot and I want to help get it the rest of the way there. |

After looking into this more it looks like the main thing I was wanting was a more realistic particle effect coming off of the waves. We could probably achieve this by doing a simplified version of smoothed particle hydrodynamics. For performance reasons we could mostly focus on the surface tension and grouping of the particles together through surface tension to achieve a water spray effect. I have a couple of references that explain how it could work below. We could then give these particles a velocity based on the windspeed. We will most likely have to improve the LOD of the waves for this to not hurt performance. Maybe these more realistic splash particles could be an option that could be toggled to reach performance goals. We might be able to use raymarching to smooth out the surface of the particles to achieve a more water like look using raymarching and it looks like there are some ways to mitigate the performance cost of the ray marching. I think with ray marching we can achieve a more realistic look with fewer particles per splash. https://en.m.wikipedia.org/wiki/Smoothed-particle_hydrodynamics |

Thanks for your interest in the project! I've been too busy the last few weeks to work on it or give the contributions coming in the attention they deserve, but I do appreciate what you are doing! There's 2 parts to the splash particles that we are worried about, splash spawning, and the splash effect. Improving splash spawning, and the foam rendering in general, depends on being able to calculate the Jacobian at each point in the displaced surface, which I don't think is happening correctly at this time. The splash spawning currently is dependent on where foam is rendering. The splash effect, as it currently stands, is mostly just winging it with a very basic understanding of particles. Doing a splash effect is beyond my current skills, so I'm open to any improvements you might be capable of implementing. I appreciate the additional resources and will give them a look over when I have time to, which will hopefully be soon. |

Ok I'll try a few different approaches and hopefully I can achieve a nice visual while still keeping performance high. I think it would be good to shy away from complex and computationally large shaders so we can still have it run on lower end machines well. It may also be good to wait for the main engine to support custom rendering pipelines before adding anything too custom/complex. I'll also take a look at the jacobian issue and see if I can figure it out. |

Hey! I'm all for improving this! I know unreal and godot are really different, but I saw the rgb captures you had in the example project and remembered this video: I was wondering if the process this guy used would be another method to achieve the splash and foam spawning you guys are talking about or am I way off base? |

@tessarakkt Hey! Amazing work!.. I'm wondering if youve seen these as reference: https://www.youtube.com/watch?v=eKgNyDGvo7s Seems like some of this could be ported over and help with some of your goals! Let me know if you'd like any help |
