Apparently they're using this algorithm for AO:

It doesn't use any additional texture inputs, so that's probably why there is no AO texture.

It should probably go in a new thread (or the wiki), as the old one is for D:OS which uses a different rendering pipeline. Not sure when I'll have time to set it up though.
I'd say that the UE4 reference could be a good starting point: https://docs.unrealengine.com/latest/INT/Engine/Rendering/Materials/PhysicallyBased/
Their material editor is similar to the D:OS 2 one, and the docs explain the concepts quite well.
