Thanks for answer! If I again would ask something: I open hunting rifle in Blender Import some random scope to it attach it to the hunting rifle now I have four parts, which are trigger, slide, mag and the gun itself NOW COMES THE PROBLEM i export the gun part to OBJ. import it to the NifTools AND I HAVE TWO SEPARATE OBJECTS, THE GUN, AND THE SCOPE. WHY THEY AREN,T IN A SINGLE OBJECT, EVEN IF I COMBINED IT WITH THE GUN IN BLENDER??? You may call me noob, but I don't understand why NifTools do that... Thanks already....
