Ok,
I have to apologize if this has been posted before and I haven't found it.
I've looked over the forums and not just this one, I understand how to extract and edit .m2 files, skins, doing geos and all that fun stuff.
One thing I don't get is - after I do the changes, how do I put the finished converted .m2 file back into say, art.mpq so I can see it in game?
:?
