Nicole, all you have to do is place everything in the my objects folder. Well, first, download the map object,
second, open it up with winRAR, third, place all of the things in my objects. So then, go to Object maker and type in the exact mesh name, one little mistke and the mesh will not be found. ONce you have the mesh, go to the first tab and name it, and name the group. You can always make a new group. There is tutorial everywhere, you should check them out before you go asking questions c:
