What I want to do is to have multiple identical cubes all following the same (non-circular) path, each with a different starting offset. And when one cube reaches the end, it teleports back to the start and continues along that path again. I want to do this without having to manually animate everything.
I tried to do what they suggested here: How may I create a continuously looping animation? by animating the evaluation time on the path and making that cyclic, but that doesn't seem to work for multiple objects.
