I love the way you used grammar in your title.
Uh, why? and plus, i have milkshape already, i've put in some skeletons and figures and i've tried to make it a map but i have no idea how to do that.
Oh, there's your problem. You can't make a map with milkshape.
i thought you could make models to insert into the map with mission editor?
Ok, now i've built a map. i want to build add-ons to go with it. do you use milkshape for that?
