Hi guys! I got a very good news for people who is searching for ocean shader with 3d generated waves! Actually I searched around and found some cool stuff from ScrawkBlog. All thanks is for him..Also the only IMPORTANT stuff is uploaded so you don't need to download the full large document . Sorry I don't have any pics.You can preview at the page : http://scrawkblog.com/category/water/
This is pretty old: http://forum.unity3d.com/threads/ocean-renderer.171651/ someone even tried to sell skrawk's version on the asset store months ago.
Nope It's all made in Unity. I am sorry I cannot upload some pics of it. I tried to post but it failed
