One of the biggest projects I have ever done. First I would like to thank @MiguelPerezSenent for guidance, tricks and tips. The main focus of this project was creation of the water and white water simulation, ocean building, material editing and karma rendering. I've learned a lot from building this project, mostly about velocity and density of the water, as well as freeing my memory space, cause for me at least took a lot of memory.
