i'm pretty sure the bone hierarchy is stored in .xac files, and yah I've gotten that far on the .diffuse files, but the problem is the dword after mipmap_height/width isn't always zero, it appears to be two separate words, and I've found that most of the time, when those are 0, everything is just simple dxt1, but if the other words are there, regular dxt1 doesnt work

Hmm interesting topic. Well heres my 2 cents.

Hashes like MD5 and SH1 can be broken in a couple minutes. That is if you know the length of the string it hashes. If it hashes part of a file and it is somewhat small, it can also be broken within a reasonable time frame. It all depends on what you know, and how you can use it to get what you don't know.

Other checksums such as simple binary functions can be broken very easily. It all depends on how you code your breaking app and what info you have at the start.

Warhammer Online hash v1.6 released June 28 for the Warhammer 1.30 update at http://code.google.com/p/easymyp/downloads/list

With this new hash file you can extract about 400mb of new models/texures from the Land of the Dead update.

Has anyone made any progress on the .geom files?
