Created in Lightwave 3D, this is a working animation of an airbrake system. Scene files are included pre-keyed to animate the various stations of an airbrake, free-running, service brake and parking brake. The object has layers for all the parts including morph targets and the front service brake housing so that an entire braking system can be animated. OBJ versions of the individual components are also included, but not animated. There's only one texture map for the threads on the cage bolt, but an environmental box is included with texture maps for the shiny steel reflections.
