Here's my first test.  This is after 1 hour 25 min. render time and I'm quite happy with the results.  The trans maps on the grass planes are fucked but I'm okay with that at the moment.    I placed a point light very high in the Poser scene and it seems to export nicely.  I love how the light spreads under her hat while her skin is overexposed elsewhere. 

How do you control the render size?
