so i need to set up a bunch of activators in my scene; i.e. you walk over to a pile of books, there is a cubic activator surrounding it, you click on the activator (in game) and it brings up a message box.

When i'm creating the cubic activator the options is asking me for a model. So i'm not sure if i'm making these activators correctly, or even how they work. Skryim seemed to be much easier.
