I'm currently working on a huge beach scene, and if I make the beach tank huge I'd like to use narrowband because there are so many particles and the process is so heavy.
But simply using the narrowband doesn't work the way I want it to, as if there's nothing underneath. It will be simulated.
I haven't had this problem in previous ocean scenes because I didn't make waves, but I don't have any solutions. Isn't it?
