Thanks for the reply. I don't even know if this is a BB race and I have no idea how to change it in the cs.
edit;
In the cs, it's named;
b_n_L-FF7AC_m
This looks to me like all of the other NPC ids in the game
the name is
L_FF7_M_SKIN.tga for the texture at least in my download (i don't play that race, i looked into the files). there is only an underwear version of it. the way i work around this usually is:
take a good high-rez tex (like http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=5635) with a skin colour most similar to the one you need and convert the colour bit by bit. use the old texture for reference. then just give the right name and copy-paste over the old texture (the folder is louis - at least in my structures. i use this procedure for every time i'm in need for a naked man (mosty the women are naked...) or a haired body or whatelse...
you'll need the naked mesh for it (from bb).
