Say I have a spline shape with several knots along it, and also a point helper. What I want is to set up straight lines (secondary, single-segment, splines) connecting each of the spline’s knots to the point helper. Creating the the lines is fairly simple, and I have even been able to get the splines to “stick” to the point helper using a script controller. Unfortunately, I can’t figure out how to also make them also stick to the knots of the main spline.
Can anyone help me with this one?
You could use a SplineIK Modifier to place a Helper on each knot, then draw lines from the one helper to the SplineIK Modifier’s Helpers.
Another option you could use, is to instance knot controllers; to keep the viewport simple.
Align the pivots, and use animateVertex to create the tracks.
