Helper tool for Expired6978's amazing LooksMenu for Fallout 4. Please direct any complaints about this very tool to me though.
Files
Preset files
Add all BodySlide preset files you wish to add to BodyGen here. You'll find them at Data/Tools/BodySlide/SliderPresetsor in their respective mod directories if you're using Mod Organizer.
Drag and drop preset XML files here
Base Preset
Optional. If you don't want to use zeroed sliders, select the preset you've built your body/outfits with. The values will be subtracted from the target presets in order to account for the difference.

Toggle presets
Preset files may contain more than one preset. Deselect any presets you do not wish to add to BodyGen.
Targets
Next you'll need to specify the actors to which your selected morphs are to be applied. Most BodySlide presets only work for female humans, so don't expect CBBE Curvy to work on Deathclaws.

Generate .ini files
Many presets include single-dimensional weight ranges from "small" to "big", but BodySlide for FO4 builds with 100% weight. Pick, which weights you want to use for a centered weight triangle, click "Generate" and you're done. Note that randomization occurs on a slide-by-slide basis, not collectively.
..you have properly built the body and outfits with any of the applicable presets (preferably "CBBE Zeroed Sliders") and ticked the "Build Morphs" checkbox in BodySlide before doing that (Gopher's Tutorial).
..the resulting .nif files end up in FO4's Data directory and aren't overwritten by the original files and/or other mods.
..the morphs.ini and templates.ini end up in Data/F4SE/Plugins/F4EE/BodyGen/YourPlugin.esp/ and that YourPlugin.esp actually exists and is enabled in your load order (this can really be any valid plugin name, including Fallout4.esm if necessary)
