Hard to explain, but I am trying to achieve a traditional 2d animation look and want to have the pink grain shader shown in the pic copy the shape path of the object. I am utilizing Grease Pencil and Geometry Nodes, allowing to create a mesh from the GP objects with no Z scale, so they are essential planes. Is this even possible?

Hope this make sense.[![photo of Blender UI with shapes discussed][1]][1]
