I've created a motion path that my elements follow. (Its a rectangle) I want the elements to continue to follow the motion path indefintely. Looping playback isn't quite right of course. I'm sure the answer is out there I just can't seem to find it. Perhaps though, I didn't "close" my rectangle although I'm pretty sure I did.
Following up on Jim's question, if you keyframed the motion path, you could go to the keyframe editor and choose "after last keyframe" to repeat the animation ad infinitum from the animation pulldown menu.
