Ctrl-Shift-U Or Image - Adjust - Desaturate

If i'm correct you mean the BUM files for Poser? (I don't have Poser so sometimes i need to shoot from the hip...) If they are like Displacement Maps (which are images in Photoshop that take the White pixels and shift to the high/positive position and Black pixels to the low/negative position) that will add surface and realism to an object. Basically you can "desaturate" the image and adjust the contrast/brightness. Any pixels in the Grey (50% range) wont have any effect on the image you apply it to. i may be TOTALLY-OFFBASE so take it with a grain of salt!! :) retrocity

In Poser greyscales are used. And it actually has to be inverted to work properly, for P4 at least.
