This tutorial will explore one of the many functions of Reactor in 3DS Max, which is a powerful tool that lets us simulate various real-life physics so that we can, for example, simulate physical behaviours such as wind, wheels and motors. We will learn in this tutorial how to create a simulation of a fan with the help of the Reactor Motor, Point Constraint, CSolver, and the Rigid Body Collection. I will show you how to use these reactors to create an animation similar to the one you see below. This is an intermediate level tutorial, make sure that you know the 3DS Max basics before attempting this tutorial.
