So - if you have a color (3-channel) attenuation map, or something LIKE one, you can plug it in that way. I don't know if that's really relevant though. I have never seen anybody demonstrate that skin appears mo'betta' if you avoid using the same attenuation on it everywhere. Prove to me you need it, and I'll believe it. So far I haven't seen it.

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)
