Do the bump maps comes as JPG files (black and white) or do they come already converted into BUM maps? If they come as b&w jpeg files, you can simply import them into the bump channel of your texture in Bryce and use them like that. If they come already converted in BUM files, you'll need to use a graphics package to convert them to b&w jpegs first. PS and (I think PSP) will read BUM files Paul
