I've gotten a bit further but wihtout those expor settings i don't think it will work.Here's whats wrong and what i do I make a simple mesh,i import the outfit.nif(the sleeepwear female).So i remove the sleepware and replace it with my mesh.Also, note when I import it,it's editable mesh with skin modif on it,so i delete the skin and make it editable poly,and add it to smoothing groups 1,than i atach my mesh with this one(so the pivot point remains as it should).Than i skin it,import skeleton.nif(extracted from mesh.bsa from fallout 3) and add the bones.Than here's a screen how i export.Oh yah i select only the mesh and use Export selected. http://i60.servimg.com/u/f60/12/10/52/34/th/pb110.jpg After that i open my mesh and the vanila one.At my mesh i select the NiTRiStrips i want,in one guide it sayed i should click mesh and triangulate,after that i enter it's data and change TSpace Flag to 16 and refresh normal,tangents and bionormals. Than i block-copy the data and i paste it over on the vanila mesh part i want replaced.And here's the problem.The part is positioned way wrong and not complete.I understand its supose to look a bit bad but im worried how it's positioned,maybe the pic can explain better my problem http://i60.servimg.com/u/f60/12/10/52/34/th/pb210.jpg
