o.k., maggie's out.  also wanted to mention that when trying to render poser girl (vickie or alyson) in mitsuba, I get rays emanating from the hip area, and they look like stray polygons.  ISTR the guy who distrib. mitsuba renderer may be attributing these to bad normals, but for some reason they don't show up in poser nor carrara, hence IMVHO it's just a bug in early beta release.
