I made a gun and some other stuff with milkshape and i got it into my map but if I put a texture on it i dont know how its gonna wrap around. i can only do the texture path thing in the obj,3ds->mdx converter so i really dont have any clue what to do.
it can't convert into .obj, its only used for new models exporting out of milkshape not for editing blizzard models.
I don't think .obj stores TVert Data anyway, so importing any blizz model into the program would runing the wrapping AFAIK
(unless ms3d supports .3ds, that keeps tvert data.)
