Can you tell us how animate a camera along the path with a target. For example if I want to procedurally generate the curve for the track. Then if I want to do a POV. I don't have to keep redoing the animation for the camera and the focal point. I had seen an Erindale video using a vertex. But there are some issues once I try to make it follow a path.
At the end of the course there's a video on how I went about it for my animation using drivers: https://cgcookie.com/lessons/parenting-to-the-carts
But the vertex parent method should also work, though I haven't used it much and would have to look at it again. I'm assuming you're following this video?
