Well, first of all, DAZ Studio is FREE! It's hard to beat that price! Plus it imports ALL Poser file formats and they will be adding others in the future. It also has full Python support, Shaders, and advanced control settings that are (in this early alpha version) starting to look like MAX or Lightwave control panels. I've only had it for one week, so I have barely tapped into what it can do. Also in the works are HDRI Plug-ins, Cel-Shade Plug-Ins, Hair-Fur Plug-Ins, etc. It uses a high-end Ray-Tracing render engine developed by 3Delight. BTW- if you already have Poser, the quick and fast way to light a scene in Daz Studio is just import your favorite lights from Poser. That's what I do. Plus DS doesn't delete one set when you bring in another, so you can actually layer in lighting with fills, spots and even POINT LIGHTS. Actually for me so far, lighting has been the EASIEST part of using DS. You can also make sky domes with your Bryce skies, so you won't lose those, and another thing I'm working on is bringing in Bryce backgrounds as Alpha Planes. Basically you can Bryce-Out a Daz Studio scene with hugely faster render times using the 3Delight render engine.
