As usual, you can find an already prepared scene set up for you in the following folder: Content / UE4ShadersAndEffects / Maps / Chapter02 /
The name of the scene is 02_07_AntiAliasing. Again, feel free to continue using one of your own scenes if you so prefer, as that is completely possible. We will however point out that we are going to be exploring some effects, such as the screen space reflections, which require some highly reflective objects to be placed in the scene in order to be able to see what we are actually modifying, so keep that in mind!
