Stefan said we should not use material-AO with GI. First of all, it increases render time exponentially. Second, GI does what AO does better. Third, when you use both, you're doubling the occlusion effect, losing realism.

Another thing - using VSS shader-based GC with GI is mathematically unsound.

Scroll down till you see pictures of V4.

I am still learning and studying P8 GI. I had an important discovery yesterday and another today. Since I'm still learning, I'm not posting tutorials yet, but I will be. If I had posted a tut on VSS and P8 yesterday, I would have told you wrong things.

Please be patient - you do not want the blind leading the blind, right? I can see a little bit now - getting there.
