First is how to turn off the lines. Set the Line Threshold to 1. Everything below the threshold is toon shaded. Above the threshold it is black. The transition is controlled by the Line Spread. But since it doesn't really work - I won't bother with showing any more about controlling the line.

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)
