New stand or sit idles are easy fixes, but dual sheathing or special body physics (boob jiggle or combat) require some extra steps.
Here I cover how to install new bodies, with or without breast and butt physics, new animations for idles or walks, and having two sheathed weapons show up on your character.
Use a mod organizer supporting FOMOD, such as NMM or MO, to include install options.
If you’re new to installing mods, see my first post in this series.
Your character can sit in a different position, cross-legged or whatever, and will always sit that way with a few exceptions. Dual sheathing, including shield or staff on back, needs a special skeleton.
Boob physics (HDT) requires a new skeleton and supporting body mesh.
Note that some older help posts recommended deleting the female skeleton, but as noted in big, bold letters on the XPMSE page, do NOT delete the skeleton file.
Note that older tips suggested adding a [HAVOK] section to your Skyrim.ini, but with latest extensions it’s been recommended (“Skyrim Stability Guide”) to leave as default with i Num Threads=1.
