I'm using Poser 6 .I have been using Poser for approximately 5 years and everything I know ,up until now I have had to teach my self .So it has been a very slow process this learning curve of mine.I know lots of people are using other render engines other than the standard Poser render engine, and getting great results.But I was told that I don't need the vrays or Metal rays of this world to get similar or even better final renders.Poser has everything you need .You just need to know how to set up the lighting and the material room .And so here I am trying to do what seems the impossible( well for me  anyhow) and prove that Poser renders are as good if not better than the forementioned render engines.Its not an, us versus them showdown of the render engines , no .Its more a point of learning and using the skills which truely make us a great artist rather than an average one .
