What is the best way to create a realistic ocean?

I am trying to create an island (with ocean all around it), I want a nice blue ocean like a desert island, I have tried using the materials in the starter content but it does not look right, I have also downloaded the ‘Water Planes’ demo and this seems better, I place down the ocean blueprint into my level and it looks good, however when I make it bigger (to cover the entire map) the waves essentially disappear and the entire ocean looks bad. Anyone know a good way to get a large scale realistic ocean with waves?

Thanks.

Your best bet would be to look into this forum thread.
