DAMN RIGHT ! There must be a way to animate those tracks ! Maybe making some height function for single-tracks based on the leading wheel rotation (from one to 18-21 rotations, witch would be the number needed to go trough the whole track) corrected locally at the places of all the suspension wheels (certain leading wheel rotation values defined for each track-piece - maybe would need just an added constant for each piece while using the same function - that might work) + a basic X-axle rotation + the same for Y forward to backward movement ... tanks would be a real eye-candy with such animation.
