If you search for ‘voronoi’ and ‘seamless’, you can find this example file:
Please note. Your surface is not ideal for a seamless morph. The surface seam isn’t tangent. Using the Loft component instead of the Fit Loft results in a more appropriate surface.
As you can see in the example file, a seamless pattern can be created with an array of three ideantical point sets.
To be able to clean the voronoi line network with the Topologizer, we can sporph 5 points per line and create lines with the first and last point. The end points are optimized so the curves are always coincident with the adjacent curves.
