Just doing some quick tests of Psunami from RedGiant Software for potential use in an upcoming personal project. You can quickly get an ocean simulation up and running with little effort, with a few presets to get you started to build on. It actually generates a pretty decent look for underwater scenes, something to keep in mind should you ever find yourself needing that.
Although I just scratched the surface of Psunami, it's pretty clear there's no way you'll ever get an actual realistic looking ocean (by 2000's effects standards, by 90s standards you're golden though!). But, as with a lot of these tools, there's a lot of potential creative applications that have yet to be explored with them. Including ridiculous blood effects for an potential upcoming zombie-themed project.
