An excavator carriage rig in 3DSMax done with reactor. The tutorial by pierrrecesar was really useful. The result is pretty convincing (and quite precise, the track goes off near the end probably because the links are too loose), though not really "user friendly" to set-up perfectly and animate, right now, the whole thing is quite bouncy for an excavator supposed to weight 120T (liebherr R984). Or I just need to use it more, I don't know.
