Yeah the AO node, if is used for something else like fractal shadow, it is called "Nasty Shadow" because they did not use it with direct light interaction. Many members argued against my term because they thought the AO node would work the same with true AO. However the AO node may be used as true AO if you know how to use it with light settings and the light nodes. It may be renderer time saving. I still have not received my P6 box and am waiting to play with it.
