Question How would you render 'water' underneath a plane having wavy CPU mesh deformations done to it?

    I have a plane mesh that I am trying to make 'water' from by deforming the vertices on CPU in a wavy motion. (I know this is not ideal for performance). But currently I am trying to figure out how to render water underneath the plane such that it perfectly follows the wavy 'waterline' of the plane mesh's movements.

    I have tried a Fog-based solution, but that did not allow for aligning with the plane's deforming 'waterline'.

    Therefore, does anyone have ideas for how to render water underneath a deforming 'water' plane mesh, such that the wavy 'waterline' of the plane's moving vertices is indeed adhered to? I'm posting in the Shader Graph category because I have a feeling shaders will ultimately be the best solution, but I don't know where to begin.

    Thank you.
