Thanks SO much for this tutorial! I’ve been using this approach for a few monhs actually, but always great to hear other people still care about this problem. I did have a lot of issues with Set Spline Cyclic node deleting the wrong edge, so I think what I did instead is to export curveu attribute from Houdini (via vertex colors) and then deleting the vertices with curveu smaller (or larger) than some near-limit value such as 0.02 or 0.98 in order to force the deletion of correct edge (although in that case I lose the first or last vertex of the curve too, so it’s not perfect neither).
