Help with revealing outfits

[BattDaPsycho]

1.6.1170
I use HIMBO & 3BA
I have TNG and TRX Futa add-on
all works fine
for the life of me I can never get the revealing outfits to work. I've tried Interesting Bits, and of course the himbo version and I grabbed the sos keyword patch for tng.
yes i built them in bodyslide. the futa doesn't show up at all they just look like regular 3ba bodies and for the himbo it's just a hole where the crotch should be.
I know I'm doing something wrong but no clue what it is.
could someone draw me a map? preferably in crayon?

I did manage to make a .ini file for Dereko's that got it to work, but this method requires the mod to have a .esp in my plugin list
[Armor]
RevealingMod = Obi's Derketo Priestess.esp
When I try this method for armor replacers I still have "the void" where genitals should be because they technically don't have a .esp
Halp?
