My friend and I are working on a project in After Effects that features a landscape scene that, when finished, will have a vehicle buzz in from off-screen. We have the keyframes for standard 2D movement down, but ideally, we want the vehicle to move in a diagonal line from off-screen toward the horizon. Naturally, the object needs to diminish in size and (if I'm correct) apparent speed as it approaches the vanishing point in order for it to look realistic. I have scoured google for tutorials for AE, but I've not been able to find anything on pulling off this effect. Maybe I'm not searching for the right keywords? I don't know. Any help, or even just a nudge in the right direction would be much appreciated. Thanks!
