Hi All. How would one make a model or character appear to be approaching from a distance? What I mean as in real world scenarios, an abject appears to get larger as it gets closer.

I would like to Green Screen maybe Daz V4 or the CP (Jess, Miki, etc) characters and drop them into another background and make them appear to be in the scene.

The reason being,  by using an AVI movie editor that supports screen in screen I can really cut back on render time :)

Thanks;;
