A question on overlapping vertices

[Dawn Whitelighter]

hey guys..

i have a problem regarding extracted models from the MPQ's. Every time i import them on Milkshape, i always have to snap and weld together A LOT of overlapping vertices. im wondring of there is a tool or feature that does that for me..

thanks in advance

EDIT: i forgot that i was in Warcraft editing tools section when i posted this.. this should be on the Animation/Modeling section right?. sorry
