Control sine wave area


I follow some sine waves tutorial to create deformation on surfaces and I wonder if there is a way to avoid the deformation of the surface edges ? So the rectangle can stay a perfect rectangle on the edges and be deformated only on the center.

Thank you in advance !


You need to make sure ‘edge’ points aren’t being affected - though different project, there’s an example here:
