The image above is my quick try at a standard lamp in Poser 4, made from Poser primitives. It uses one of my Omni-12 lights, with Dist End set to 2.220, and intensity set to 1.200. Casts Shadows is off for the light bulb. The image was rendered twice, once with Casts Shadows on for the light shade, and the second time with it off. The 2 images were imported into PaintShop as layers, and merged, the 'Lightness' was adjusted, no other postwork.
