I use james in studio quite often with genitals on, all i did was load james in poser, be sure genitals are on, save him back to your library(with genitals on)...then when you go in studio, load the one you just saved, be careful using any james poses that came with p6, when you click the pose it will switch the hip back to gen off. Hope you get it to work, studio renders with so much more detail than poser
