theres an option in the .3ds exporter to do that (its default i think), so as long as you stick with short filenames for your texture images you wont have to make any changes, otherwise youll have to do some fixing in milkshape but nothin too hard. just be sure you attach all the parts of the model togeather (wiff attach tool of course!) or itll be all weird. you can use more than one texture image tho
