The only file you need

This is a customized version of the Pampas BodySlide Preset that I tweaked a bit for my character that's used in the screenshots. Download and extract to
(game location)Steam\SteamLibrary\steamapps\common\Fallout 4\Data\Tools\BodySlide\SliderPresets

This is the same as the main file. For those who are having trouble downloading the regular compressed ZIP.
