It was back in March some time that Uwe Schweer-Lambers (Equiloud) shows how to create an appearing animated ribbon using the Mograph Module Cinema 4D, and here, animator Mac Lanphere adds to the technique, adding a fluid-like wave motion into the ribbon effect, bringing them to life after they have been drawn-on created.

try changing the interpolation of your tracer, something like b spline + uniform, one of those combos

Mac uses the Cinema 4D MoSpline to introduce the waving motion into the ribbons. Mac walks through creating the animated ribbons and also provides some tips for troubleshooting or fixing problems, including creating some refinements by changing the interpolation of your tracer object.
