As others said, IDL is preferred over AO of any kind, and if you enable IDL, AO is automatically ignored. (Unless you explicitly override that for special cases. Examples would be using AO for crevice detection to make grime.)

But meanwhile, if you really need to use P7 style rendering without IDL, I will post a version of the Albino shader with AO. But you have to come back and tell me you really want that.

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)
