Smooth Bezier Spline


This node will edit the handles of the input spline so that the spline get smoothed.

In fact, the node just set the length of the handles to the smoothness value and align them to the tangent line to the curve at their location. So if the smoothness value is set to zero, the bezier will act as a poly spline since it has no handles.

Note that this only work for bezier splines and not poly splines.


  • Spline - A spline.
  • Smoothness - A float that defines the amount of smoothness. (the length of the handles of the bezier spline)


  • Spline - The smoothed spline.
