This mod was made by psychodog studios/liztail. but has long been forgotten.
I have merely made them into NMM/VORTEX/MO2 usable files.
I do not take any credit and merely bringing this mod to light and doing some edits.

the better bodies 2.4 on nexus has this in it . but due to the edits to the meshes . produces clipping when holding swords.
the original mod on nexus with this animation does not. and thus I recommend that version over 2.4 .

there is no peanut gallery variant . and honestly if you use it you suck.
nude and underwear variants only.

again, I take no credit and if asked to take down I will. but morrowind mods are so scattered and hard to find . i think this would be helpful

ps : not many images because im fairly certain the majority of you already know what im talking about.

also roberts has the sword finger clipping bug due to thin fingers.
normal BB with this mod is the only way to avoid it.

http://mw.modhistory.com/download-56-11353 it's a body retexture for better bodies . that's tone matches the vanilla heads better much better than normal BB.
and overall looks better.
