Ok so first thing’s first: the links for everything you need to make your own default female body in fo4, in case you don’t have it already.
These are NECESSARY:
Fallout 4 Script Extender: http://f4se.silverlock.org
CBBE: www(dot)nexusmods(dot)com/fallout4/mods/15?tab=description
Bodyslide tool for CBBE: BodySlide and Outfit Studio at Fallout 4 Nexus - Mods and community
This MIGHT BE NECESSARY (idklol):
Atomic Beauty mod: www(dot)nexusmods(dot)com/fallout4/mods/12406?tab=description
(I seem to recall this mod adding some sliders to the Bodyslide tool, but this was a while back so I’m not quite sure of that)
This is HIGHLY RECOMMENDED:
LooksMenu: www(dot)nexusmods(dot)com/fallout4/mods/12631?tab=description
(This mod allows you to change your own body and those of NPCs using the console command “slm”, almost exactly how you would modify a character on a new game save)
OK. Now comes the hard part: learning how to use Bodyslide effectively. Here’s a guide I threw together that has the values for my own personal preset, alongside a description of what each slider does (to the best of my ability). REMEMBER that all sliders can accommodate values that are unreachable by moving the slider (negative numbers + numbers >100)!!!

Here’s more helpful tips for using Bodyslide:
- There’s a preview button where you can see a model of your values before you build the preset file.
- You can press the batch build button to build refits for all of the base game + dlc outfits, so they actually fit your model.
- Larger bodies may have issues with clothes and hands/arms clipping into the body.
- When you batch build, be sure to select the body base that MATCHES the one you used when creating your preset. I recommend CBBE Physics.
Finally, if anyone else has helpful tips for fo4 modding, Bodyslide or otherwise (but preferably sticking to body edits/maybe outfits, for sake of relevance lol) please feel free to share! Also feel free to share your own value sets for your own favorite body presets! Fallout 4 is a game that has TONS of replayability AND customizability, so I really hope this guide helps you make the most of it. Best of luck, and have fun
P.S.: I got an error saying I could only put in 2 links so for the other links, just replace the (dot) with an actual dot lmao
