I'm doing it wrong then. I've tried putting just the texture_library folder (from your post, annemarie) in live/localdata - I tried the 3.5.1 installer - neither the TOS Mirror or TNG Skant costumes change. There another localdata folder (using steam) I tried that and nope. I even tried just putting the files in the localdata folder with no folders, nope. But if it's still working for you than there's hope. Can you (annemarie) please walk me through your install and dress process?
all i did was run the installer with JUST the replace clothes options, no jiggle or movement replace
then I put the files in that I zipped. and I do have STO under the steam commons. in my install there are 2 sto folders:
E:\SteamLibrary\SteamApps\common\Star Trek Online\Star Trek Online\Live
The problem with nude male bridge officers is they will not have penises as there are no meshes for them. If you were really good and made the Caitan tails for everyone mod work again and then modify the mesh to a penis you might make something bearable.
So for now, don't try to show your emasculated male toons on the bridge.
That was why there was a most NPC toons female mod at one point.
