How to Morph Between Splines in Cinema 4D

October 8, 2014


In this tutorial I’m going to show you a really cool workflow for morphing between splines using Cinema 4D.  This kind of spline morphing animation is awesome for using in conjunction your 2D workflow in After Effects by applying a Cel Shader material to your splines.  The nice thing about using the Cel Shader or just flat colors in the Luminance channel of your material is that when you use Cineware, these type of scenes render out super fast as a Cineware layer in After Effects because you’re not doing heavy shadow or shading calculations.  So to begin, I’ll go over the thinking behind the method I chose and how to achieve a nice, smooth spline morph.  Then, I’ll show you how I build a spline that is able to be affected by effectors to morph from one spline shape to another.  I’ll demonstrate how to use the Inheritance Effector to achieve this morph and ways to make your morph look super sexy and bouncy!  Finally, I’ll show you an alternate method of using MoSplines to morph and the shortcomings of going that route.

Here’s one of my previous tutorials that shows you how to create the 2D illustrative materials using the Cel Shader that I’m using for the objects in this tutorial:

Using the Cel Shader to Apply an Illustrative 2D Style to 3D Objects in C4D

And here’s the scene file I used in this tutorial that you guys can mess around with:

  • hey, nice workflow. would you see any possibility to connect the spline-wrap size profile (the thickness of the rendered stroke) to the two matrix-objects? so it changes according to the inheritance falloff.


  • i have a little problem in my cinema 4d ( i dont have the cel shader ) what should i do

  • Is it possible to morph to a third spline shape? (and a fourth!)

  • is it possible using the posemorph to morph splines-objects like this ???
    …and would be fantastic to get a scene-file to every tutorial…;)

  • the download link is not working 🙁
