'Morning n00b, I'm sorry that I can't offer any help with the curved lines on the water, being that I am also a new user, ( one week ). What I can tell you is, I also get these same lines with a couple of the different waters included in Vue 4, and I get these lines from an "above water view" rendering too. Maybe someone experienced with Vue 4 can shed some light on this subject for us? Have a good one . . . Mark.
