3ds Max Tutorial - Part 1 - Slider-crank mechanism with Expression Controllers
Part 1 of a step-by-step process for using expression controllers to rig the kinematics of a slider-crank (piston) mechanism. Motion in the direction of a principal axis or at any angle is addressed.
Part 2 is available at: • 3ds Max Tutorial - Slider-crank mechanism ... is provides an easier method for rigging a piston at any orientation and to allow the mechanism to move is space as would be found on a steam engine.
