Properties
The Theme-O-Matic records properties that fall into the following three categories. Most of them are set using your viewer's regular "object edit" window.
Object properties are set once for the whole object
Prim properties are set for each and every prim making the object
Face properties are set for each face of each prim making the object.
To create a theme you will usually have to alter one or more of these properties in your viewer. More about this in the next chapter.
