Schlumpf, thanks for your help.
So, to change the weapon size, I would have to work on changing the .m2 file, but, do you know how to "navigate" thro the m2 files, I mean, how can I open the file and explore the configuration contained there?
Im guessing that if we can change the m2, we could do some cool stuff like changing the model animations, make an human attack like an orc, or dance like a dwarf...
