I dunno what u mean by that but if its importing models to your map and you dont know how to do that just ask me next time you post a reply and I will help you.
Editing models?, i use War3 model editor, war3.mpq is at warcraft folder, for me its C:/program/warcraft 3. you can also use warcraft 3 viewer, you press: Open mpq file, then go to C:/program/warcraft 3 and choose the War3.mpq file. when you have opened it, a list of MDX and something else turns up, choose something there.
And of course, if you want to make changes in the models, you will need an application such as Maya, 3Ds max and so on. There are converter programs if you want the models imported I believe.
Maya PLE (Personal Learning Edition) can be downloaded from this site.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
