I've created a path that has vertices animated to follow an underlying map. The map is a slow zoom in on Google Earth looking at the ground at about 45 degrees, so each vertex of the path is keyframed to follow a point on the map to allow for perspective shift during the zoom. This path will be an animated route on the map.
I'm now trying to make a glowing dot follow the path as it's revealed - is there a way to make an object follow a path that is itself animated with keyframes? The only tutorials I've found show how to paste a static path into an object's position attribute, then animate the object along that fixed path, but this method doesn't allow for a path with animated vertices.
