Following the previous tutorial, now I'm going to explain how to animate doors and windows in your building. Basically there are two types of doors and windows. The first one is default doors and window from 3ds Max and the second one is the one that you manually create. But in this tutorial you can also see that both types can be combined together.
Though its easier to animate the default doors and windows from 3dsmax, it will require more work when you want to add accessories such as doorknob, handle and such. So I don't think its suitable for close up pictures.
