Creating a semi-realistic ocean in blender

No.509409 ViewReplyOriginalReport
Does anyone know how to create a nice looking (but low poly and baked) ocean that I can import into Unity? I don't know how to make the material look good and, basically everything.
I'm pretty new to blender.
Also, the ocean kinda flows into a river and ends out in the ocean again, but it looks like the water melts through the island. How do I make it seem like the water is crashing or flowing?
