I'm kind of naive when it comes to lights and materials, so I'm having this problem where any white object I have in a scene, when hit by IBL lights in Poser Pro 08 ( such as these: http://www.renderosity.com/mod/bcs/catwalk-/60715 ), it becomes extremely oversaturated, like I have the white balance set way too high for it.  Does anyone know what I would have the change in the Materials tab to get it to appear just like a white sheet of paper under a light and not reflecting everything that hits it?
