I've got one main spline that acts as a driver. This spline will have many child splines that are copies of it, but the children should be offset based on the parent's size. Higher radius -> bigger offset.
The problem is, I can't find any way to access the parent's radius at a given point. Get Spline Samples and Evaluate don't have this information.
The Spline Info node can access radii, but it returns one radius for each point in the spline, and ideally the children will have much higher resolution than their parent. Is there any way to interpolate between values like the Sound Falloff node does for spectrum data? Is my best option to make second "helper" splines to store the data?
