If you haven't seen some of the remarkable images rendered using "Reality 3 for Poser" to LuxRender, then you must live in a cave; not that there's anything wrong with living in a cave. If you're finally venturing into the light and are curious how you too can create uber photorealist images from your Poser scenes, check out these two free tutorial videos from PretA3D, the developer of Reality 3 for Poser.
The formula for this level of ultra-realism is pretty simple. Use any recent version of Poser (Poser 9, Poser 10, Poser Pro 2012 or Poser Pro 2014), get a copy of Reality 3 for Poser for only $27.95, then watch these two videos. In a few hours max, you'll be a master photorealist too!
