RKT Utility Splines is the kind of tool that should be implemented by default in Cinema 4D.

Pierre Rapin –


Optimizing, prepping splines to morph between each other, art directing the look of my splines, using modified splines as sources for matrices/cloners. I could’ve used it in a lot of frames I had to design before.

Effortlessly smooth out any spline, softening harsh edges and creating fluid curves from the messiest input.


Choose from 4 different algorithms to eliminate points that don’t contribute to your final result.


Parametrically control the number of points in your spline using Step, Random Step, Count, Random Count, and Subdivide, perfect for rope simulations and so much more.


Remove overlapping points, redundant points, and any segments so small that they’re not visible.


Convert unruly splines into clean, smooth lines for greater flexibility and control over Bezier handles. This plugin is the opposite of baking down a spline!


Extra modes enable more advanced effects. Automatically animate a jittering Random Resample.


Maintain your overall shape by counter-scaling as messy edges are cleaned up.


Add extra detail to rigid splines easily with RKT Smooth, then optimize with RKT Reduction!
