I am using motion and making 2D to 3D animation. Basically cars moving along a highway for traffic studies. The only problem is, is that I can't draw and am stuck with the angle of the intersection and car I use. Can I import fully 3D rendered cars into motion and manipulate them? The 2D affect is OK, but 3D has more impact. If not motion is there another MAC platform program I can use. Maybe a CAD program? If there is a powerful program that allows you to have intersections and roads that allows you to place cars and pedestrians that would be good.
