all you need is this zip file:
NM Now find your install:
mine is in a steam install, yours may be arc or something else, but they all have this path:
E:\SteamLibrary\SteamApps\common\
Star Trek Online\Star Trek Online\Live\localdata\
unzip the NM file into the localdata folder and you may have to move the contents so it is Live\localdata\Texturelibrary

it should look a lot like that
each folder under avatars should have wtex files, like these
F_Beltcloth_Formal_Gown_C.wtex
F_Skirt_Formal_Gown_01_E.wtex
F_Hips_Bare_01_D.wtex
now those are just examples and you should have 130-150 files total
