How to find a nice water material

I know I maybe dream in color, but any idea if there is a nice free water material somewhere .

The only one I found is this: Water Material - Work in Progress - Unreal Engine Forums

And it work fine but there is these annoying line

I dont know why they are here, but I have biuild the light so it must not be theproblem.
Again, maybe I am dreaming in color but if anyone know ifthere is a nice free water mateial somewhere or How to slve these anoying line I wouldbe very gratefull.


In launcher you can find WaterPlanes project
Also there are few different materials in example projects - effects cave, vehicle game, shooter game, kite demo, and maybe else…
