Quote - Regarding the gather, I find that the effect is usually too strong. If you're plugging it into Alternate_Diffuse, choose a gray instead of white for the value multiplier. This will make the amount of gather much more subtle.

I see the gather get a little bit over the edges in P7... can't see anything on this website you posted above it is clean so no flash or anything visible ..
I made a quick test before so not exact.. I never use white surfaces in my final renders and for the best effect I spend 12-16 hours on so not compared to 2 min preview.. but well we have to keep it simple and give the oportunity for the users to play with that.. the self made cookies taste the best right ? ;) I made one pic using only gather nides for the surfaces where was not specular and everything based on reflect and fake GI.. it was looking very natural, rendering time was a killer but well a good quality..  every surface and material need own attention and different settings.. even for GI, we can use one script and light everything the same way.. this will go to nowhere.. skin or wall reflect light different ways that why in some progs everything looks not natural at all , nice for the eyes as illustrations but not photographic effect..
