There is no requirement to rename all your items, as long as you're willing to add rules for the names they already have. Vestmann was choosing one of two approaches based on his desired workflow. Seeing that he had many items whose name begins with the letters si, he made a rule for si* and that took care of finding the props for the standard toon shader to apply.

If you have 20 chairs, and they are all called chair_1, chair_2, chair_3, etc, then add a rule node for chair* and all those are covered, without renaming them.

If you have 3 tables and two are called Table_1 and Table_2, and the third is called Desk, you add rules for Table* and Desk and they're covered.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
