animating points on a spline

[_Aka_]

The Spline To Mesh editor tool creates a mesh based on the spline as it is when using the tool. It does not update the mesh when the spline is updated.

I see two solutions to achieve what you want:

1- Use Curvy Spline's API to execute the tool whenever the spline is modiifed: https://api.curvyeditor.com/FluffyUnderware.Curvy.Utils.CurvyUtility.html#FluffyUnderware_Curvy_Utils_CurvyUtility_SplineToMesh_FluffyUnderware_Curvy_CurvySpline_

2- Generate the mesh using a Curvy Generator. This one updates the mesh automatically. I attached a modified version of your scene achieving that. You can learn everything about the Curvy Generator here: https://curvyeditor.com/documentation/generator/start
