I want to populate in-between splines positions by several (user defined number) of splines. How can I achieve this ? In this example, my curve has 3 splines: I can deform splines along normal, and to their respective sides, I would like to fill with other splines between given extreme positions.

Moving curves

Edit : Solution: We need to instanciate via mesh line and instance on point, then capture spline indices:

  • $\begingroup$ Thanks, Mix Node is interesting to interpolate positions for one curve, but my main problem is : how to populate with several curves ? (ie : 6 in my example, but could be more) $\endgroup$
