Reactor Motor Tutorial By Aziz Khan
Hello and welcome every buddy to my (Reactor Motor) tutorial.
Many of the people who asked me about reactor function in 3ds max and they asked me different kind of question about reactor in 3ds max and I tried to answer them, I realize that I should write some reactor tutorials for those who need these kind of tutorials and to help them, I will be happy to share my knowledge, some one said (Share your knowledge that God Will Increase in your knowledge).
Ok lets come to the main point, we will learn (Reactor Motor) in this tutorial, how you can simulate a fan to react as fan in scene it will possible with help of (Reactor Motor), (Point Constraint), (CSsolver), and the (Rigid Body Collection) I will show you how to do and use these (Reactors) name mentioned above.
