Hey,
great job on the water, I really like it so far. Also the plans you have for it sound great.
I copied the water over to my project and it looks great, but I just have one, like you can see in the picture, in a certain radius around my island, the water gets those open spaces. On the left side, its alright, but on the right you can see where the radius starts.
I have not found a way to fix yet. Hope you can help me out with it 
Thanks a lot and keep up the good work
