You shouldn’t do Sine of AbsWorldPos.x , you should use the ScreenPosToWorld for all the world positions there. The sky distance should never come into play.

Should be more like this

Z mask = ScreenPosToWorld.z - WaterHeight + Sine(ScreenPosToWorld.X + Frac(Time)))

Yeah, it works. Thank you Ryan!

Here is very basic setup with sine waves:
