I need lots of help... with Maya too. I am trying to do a 3d graph, where the arrow animates up and down over a period of time (45 seconds) For example, The rise and fall of the stock market. As the camera dollies across a background, the arrow moves up and down as it is going side ways. The tip of the arrow is always in view, but the "tail" of the arrow starts at one point and continues to grow. And the arrow head leads the way.
