There are several methods to morph Splines in C4D. One is to use
the cloner object set to blend mode together with a Plain Effector,
which blends between given objects.

But in order to stay parametric and have a smooth transition with your
Spline-Objects you have to retopologize them. This is where MoSpline comes in.
It helps you to reinterpret your Spline-Objects. This shows only the basics
of the technique. It gets a little bit complicated if you want to morph
for example Text-Splines where one consists of several Spline Segments.
(9 for example). Also the order of the Spline-Points plays a crucial
role while morphing. But this should give you a good start on
experimenting yourself. (no audio)
