your Mini Guide Helped alot : but do i change the avatar items to the set name : " avatar_m_angel_wing_dress.bsr change name to clothes_08_ba.bsr & clothes_08_la.bsr(u have to copy the avatar file because it will be edited 2 times) "
or change the Set to the avatar name : " And now you will change the files (those you extracted - the set) BA and LA (light_09_XX.bsr) to avatar_m_halloween.bsr (this is the chest)." i am confused

and after i do this changes to what path i import this stuff ??
