Poser totally ignores external smoothing and always does it's own - might as well just strip out the normals cause they just waste disk space. Also, to add to what BYS said, no lights! "why doesnt obj from may show up in poser 4? " Are you getting anything in the pop-ups under the main window? Especially under the Props sub-category? If there's something there, does it still not show up when rendered? The RT preview is real picky about which way the faces point and which way the object is "wound" (vertex list order) but usually renders these types OK.
