For Poser and Daz characters, I like what Poser renders so I will save the rendering as a .tif and export it to Vue.  In Vue, I make a billboard and put it there along with its mask.  Then I adjust Vue's lighting to match that of the figure.  Works great and you can put many figures into Vue as billboards and it won't bog down the computer.  The finished rendering doesn't look too bad.  Jan
