Hi weengle, Yeah sigh...MANY, if not most of us get the "unsupported file format" error message when trying to load a PZ3 with those .BUM files. It should work; it was advertised to work, but for most of us it most definitely does notwork....... On the other hand, you can take those .BUM files, make a copy of them, so as to not over write the riginals, and then rename them with a .bmp extension. Then you can manually load them as bump maps into Vue, under the bumps tab in the material editor, with the "mapped values" selection checked off. You'll want to lower the Gain way down, to like maybe around .001, and you might have to set the Y scale for each one to -1.000. That's about the best you can do for the time being. E-on seems to be staying amzingly quiet as to why the .BUM files don't work. Annoyingly quiet, for that matter. I'm thinking about emailing them and asking if they have some sort of "official" answer I can give the dozens of people who have asked about this.....
