That's right, it does that. Why? I don't know. Seems kind of strange for them to want to take a 100 KB jpeg and turn it into a 3 MB .bum, but there is no way around it without the Pro Pack. So, while you wouldn't be able to use the .BUM file in Vue, you still can use the jpeg, and it works the same. The bad news is, it takes a few minutes to apply it, and get it right, but the good news is that once you have it right, you can save it as a Vue .mat (material) file and reuse it often, much easier. So if you use the same bump files for many different characters, it's a good thing to save them as Vue .mat files. On the other hand, you could end up being one of the lucky ones that have never had any problem with the .bum format. It DOES work for some before the 4.05 patch, but not for others, and no one seems to know why. We have a saying around here, which you can find alot throughout these messages in this forum: "Vue funny sometime. " ;)
