I'm not sure I understand whether you want sharp edges or not. But the best thing you can do to improve any obj file, is run it through uv mapper. Did you import to Poser in obj format? I use max and this is what I do. Export from max as a 3ds file, import to poser and get the size right, export as an obj, then open the obj in uv mapper and use 'split vertices' to give me sharp sides. Then I re-export the obj WITHOUT normals (Poser ignores normals) to cut down the file size and open it in poser with all options off. This may seem a long way to do it, but it works for me, I've had nothing but trouble exporting obj from max. mac PS uv mapper is free. See link.
