A final afterthought. You didn't say which version of Poser you're using. If it's Poser4 you're using, then there's a strong chance that the geometry rsr files (which P4 uses alongside the geometry object files) might well have got corrupted during the power failure. If that is the case then it may be good news, as your editing task will be simplified. You'll need to open the pz3 in a text editor, and search for all references to the object (.obj) files in use. Then open the containg folders on your hard drive and delete the rsr files which accompany these objects. Poser will regenerate new rsr files when you next open the pz3.
