if there was the normal GI i wouldnt told him to use it.it takes to long.
i was watching some video from MODO and they have a fantastic GI . renders fast and gives fantastic results. not physical accurate but you dont notice it.

if we had some nice fast indirect lightign in poser then this would be amazing. but with some spot lights we can do magic. for example the irridiance caching in poser 7 was an amazing update. i can lower it and get fantastic results with low AO. when using darker AO i do 50.  never go to 90 because you would no notice the difference in my renders.
