I am having trouble assigning the materials ID's properly, and I may be confused about the manner to do it. First, I attached all of the elements per step 181. I went to the Modify panel, under the elements sub-object group, and expanded the 'Polygon: Material ID' roll out. Here's where I had trouble. I can't seem to find direction in the tutorials or texts as to properly assign materials, if this is the correct place to do it. I had trouble selecting and isolating the individual elements of the object. Certain parts of the back pillows are unable to be selected, doing a Ctrl select. Also, I am not sure what order to select the objects and then assign a material ID #. Whenever I make a setting, it is easily undone or I am not able to retrieve the settings that I just made.
I watched the "Building a Multi-Sub Object Material" tutorial on lynda.com, but after attempting this method, I do not believe that this applies to what the text is calling for.
