Geoset merging prob

I was trying to do a geoset merge, it worked, although I repaced half of the tauren with a NE shield (wich was not QUITE what I wanted :P) and I was wondering, if, model editing was easier, like on realm designs models, they are only blizz ones but they have extra bits on them, is this Geoset merging or done with a modeling program/notepad?

thx,

u can simply attach items to units if that's what you are doing

btw, is this bifrsot related? =P

I know about attachments (Im not st00pid :P) that method takes ages, and you have to do it for every unit thats got attachments, and it can sometimes look dodgy, Im trying to add the bits permanently

Edit: I'm trying to find this out, so we can have some variation on the skins that we are replacing in the game

as long as it wont take up too much size of the map

itl add like, 2 bites to the MPQ :P
