That's true lilkc. Sometimes people export with faces flipped and sometimes faces/polygons get flipped randomly during export. One of the many downfalls import and export. I'm not quite sure why this happens but I know that most software allows you to make doublesided during export or to flip faces. This is not uncommon and the comment about nurbs may also be true, however Lightwave will not allow you to export using subd. It must be turned off in order to export. It helps to know someting about modeling and polygonal manipulation. My tip for the day towards poser users.
