So, this is only at 35 samples right now (single sun, ran it for 3+ hours at 2880x1680.  Smaller would have been much further along).  The glass on the car isn't showing up like I want it to, the glass in her glasses on her face isn't showing up well (yes, there are a pair of glasses a car, Doc/Bob).  They are set to architectural, with a reflection color of a gold-ish color, and white transmission.  I'm trying to get a good semi-mirrored (i.e., mirrored, but transparent, so that there is a fair bit of reflection) look on both.

Any comments/suggestions?

 

BTW, the Porshe model is availble from here in the freebies:Porsche
