Hey all. I am using vortex to download all my mods. not good at modding, not even if my life depended on it. i cant seem to get every body replacer to work. tried them all. tried for both fallout new vegas and fallout 3. the top is removed but never the bottom. it still clips through the armour as well. please help me in the form of a way i can understand. this is making me pull my hair out.

i got my game downloaded through steam. i dont know what file to throw the body modifier into. i am new to this whole thing
