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?
