{IInstalled PoserProPack, Install Poser 4 seperately as "Poser4 only" file, convert your JPG's to BUM in "Poser4 only", and move them to PoserProPack. Awkward, but it works.} Philly, there's no need to use bum files in ProPack. PP uses jpg bump maps and bum files will give you very weird results. There's a little trick to keep you rsr's from getting corrupted (something Poser seems to LOVE to do). Once you have a new, uncorrupted one, open properties and set the file type to read only. Then Poser can't corrupt it anymore.
