getting CBBE to work with nude mods working properly

[fishsticksandwich]

hey everyone. im super new to modding as it pertains to most things skyrim related. and im looking for a little help for the cbbe nude mods and such. i downloaded the cbbe mod and applied the script extender and most of the basic stuff when it comes to modding for physics. though im running into some problems. after making my body preset, the body applies to clothes and doesnt seem to apply to the vanilla "naked body".

this presents me with the two main issues i need help with:

1. how do i get my nude mod to apply to the vanilla "nude" body?

and 2. how come the slider doesnt apply to the vanilla body even if the first question wasnt in the picture?

im totally blind when it comes to these issues, and i'd really appreciate a bit of help if anyone knows the most likely rookie mistake im making, thanks a ton
