This chapter discusses rigging of the carriage by using a Link Constraint on the Branch node and layout controller. The tender, that big sphere holding all the fuel for the steampunk train, is rigged up next. The solid frame on this carriage has its own locator and controller. Although not necessarily needed, it does give some additional control over the main carriage. The front and rear budges have an identical setup of that of the rear budge from the first carriage. The controllers are going to be used for the actual connection between each of the carriages. Freezing Transformations allows to set zero values for the controllers or other objects in the scene. By doing so, one will have a reference point for the controller, which means that when transformation values are set to zero, the object will jump back to that exact reference position.
