Reactor is a powerful tool that comes with 3d Studio Max, it makes it possible to simulate realistic dynamics based on physically-defined properties, such as hard body, soft body, cloth, and liquid. It can simulate the reaction occurring when a box falling from a high place hits the ground. This could be compared to all the time required to do the same effect using keyframes, and that wouldn't still give us a realistic animation similar to the one possible to create using reactor. This tutorial will teach you how to simulate car motion using the Wheel Reactor. The video below features the result that we are going to create in this tutorial.
