This is the second of a 4 part video tutorial series geared to teach you how to rig a tank in Maya to a professional level. Please keep in mind that this rig is not easy to achieve so be sure to know the rigging basics before watching. In this video, "How to rig a tank in Maya - part 2", I will be using vector math techniques to setup the wheels so that they move correctly in any direction and distance. I will then connect the wheels so that they drive the treads that we setup in the previous video. The next video will setup the hull control, giving us a suspension and weight shifting effect.
