About Wings3D. Wings, for it's price (free), is most probably the best modeller for Poser, but there are certain limitations. Firstly, it lacks some of the more advanced tools, and it has a limit on the size of object it can handle. But that said, every model I make in Cinema 4D, Hexagon or Shade, I import into Wings to check it's compatibility with Poser. If the model won't open in Wings, you know it will have a problem in Poser. Wings shows up inverted normals, double sided polygons, n-gons, etc, better than any other modelling program (and I have tried them all).
