No more needs for many similar meshes!

Grab Z-aligned tangents of the mesh and push it with some strength. Use UV coordinates for masking to define on which vertices we want to be moved. Multiply it all and send to World Position Offset - and viola!

Here is a mesh, which I've used for this effect - simple donut plane with planar UV-mapping. If you're feeling lazy, you can download this mesh from here: goo.gl/ZEzLCa
