rapid coral
I am trying to make a mesh move in an undulating manner while also varying the intensity of the movement from top to bottom. When I do this, the top and bottom of my mesh open up while everything else remains OK. Is there something I can do in shader graph to prevent this?

It's hard to know without seeing more of the graph.
But the usual culptris for a "split up" effect is if you are using the normal to push the face, and that the mesh has hard edges.
