In this tutorial VideoFort Don teaches you how to make tracer trails using Cinema 4D’s tracer object. Start off by choosing a star shape and set your keyframes for the motion.
From there go to the MoGraph menu and choose tracer and in tracer object atributes drop your star shape in the trace link section, if its not in there already. Then create a circle and drop both the circle and star into a sweep NURBS object. From there Don shows you how to refine the tracer trails by going into details section of the Sweep NURBS object.
