I've been seeking for this for about a month! I have EXACLY the same question
. I mean i have extracted all the .package files and i got everything I need! I have even converted the .dds to BMP to use as textures! What i miss are the .xmod files! If I manage to convert or to read the .xmod files as graphic models I can recreate the WHOLE WORLD OF AGE OF WULIN!!!!!!!!
So, I will search more and if i find an answer to this maddness i will tell you too.
But if you find it before I do, please help me too
