I have never seen the actions that add rule or copy nodes do so in anything but the material you currently have open.

Is this something that you did one time, or it happens over and over?

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)
