I'm currently trying to create a wavy pattern with shader nodes, each with two opposing wavy lines running diagonally across a square area.
However, I want the curves to end up with a seamless pattern so that this can be applied to a larger mesh.
Nodes are not new to me, but I am just learning how to use shader nodes.
My first patchy attempt at least got me as far as creating a wavy line, which unfortunately isn't much yet:
I honestly have no idea which direction to go further in here, however I was thinking of mirroring this pattern, then multiplying it, then rotating it $45°$.
I'm pretty sure that's probably the wrong way to go though.
Does anyone have any ideas or tips on how I can create such a pattern?
