Versus the translucence channel, which is basically no lighting model at all. Whatever you set it to goes to the render, just like ambient or alt_diffuse. Of course if you plug a lighting node into it, then it behaves like that lighting node, but this is no surprise.

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)
