Lookoo, I have been struggling with the same question. From my studies to date ( work in progress) it is just not the render engine you have to look at. You also have to look at 1. What can be done to enhance the Poser texture - layered bump maps, etc 2. The lighting options and then the 3. Render abilities. I have attached a work in progress. All I have done to date is play with number 1 in my list. I currently working on the lighting. All of this was set up in Poser and moved to C4d for "playing with". For me a steep learning curve!
