Thanks for the info and link, but I'm  still hopelessly in the dark.

I've got Terrain Tools and I've tried setting it up like in the link you provided, but all I see are evenly spaced waves with no foam or turbulance whatsoever.

To be truthful, I don't know what I'm doing with Terrain Tools since there really are no directions I can find that tell me what all the setings are for.
