In this lesson, you set up the scene by opening a 3ds Max file.
Open the sample file:
You are presented with a simple scene containing some stairs, a floor and a character model.
At the moment none of the objects in this scene have any physical properties associated with them; this is what you'll be adding over the course of the tutorial. reactor essentially adds physicality to scenes. To properly simulate dynamics, objects must have real-world properties such as mass and friction assigned. By adding these things to your scene, you can create a simulation that mirrors your everyday experiences, or if you'd prefer, an alien world with gravity pointing to the right!
