I'm trying to animate a trapcode 3d stroke dotted line. I've adjusted the step so that the stroke looks like a dotted line, but I can't get these dots to move smoothly along the line. When I adjust offset or start/end, it just changes where the balls start / finish. They don't actually move along the line.
I'm trying to create a "crawling ants" marquee effect, but much larger. Since this will be used to show water currents on a map, the strokes are curvy lines, and so I can't just cheat by moving the position of the layer under a mask etc. I need the balls on the stroke to actually move.
Any suggestions? Perhaps 3D stroke is not the way to go?
