You don't really have to search, the materials are always at the very end, at least on all the CR2's I've seen. I don't bother with CR2Edit or CREditor, I use MS Word (Curse you, Bill Gates), since it is really just a text cut and paste operation. Wordpad works well too, except for the really big CR2s. I can make a bunch of MAT files in nothing flat, my SMV Essentials clothing pack has about a dozen or so included, I've go naming conventions worked out so some MATs will work with mutiple items. Incidently, part MATs work too, for example you can just turn transparency on or off with a pair of them, while you have others that set colors or maps that will be unchanged.
