📋 About This Mod

This mod adds BNB and BB(Bouncy Butt) support for a sizable portion of Type 4 vanilla outfit conversions, excluding armors where it makes no sense for breasts/butts to jiggle. Almost all outfits in the game are covered except white legs outfits, they will be done later when I feel like taking that nightmare on.

Some outfits have had their polygon counts and overall visual fidelity slightly increased along with bug fixes in some areas if I notice something I can fix easily.

The BB addon is a bit experimental as I just rigged the boob animations to affect butts too to a much lesser degree, expect some jank here and there and of course results will completely depend on your animation sets. Because of this, you can now have animations for the best outfits in the game; the stealth suits!

Some of these outfits are based off of More Modest Type 4 body and armor which are based off of type 3 body and armors; partly because I prefer them and partly because I couldn't get some outfits working. :(

I am open to suggestions on what to change, and if there are any issues please report them I will fix them if I can. If you want an outfit covered, ask me and I will do it if possible.

Install:

Get a set of BNB Animations such as from BNB Lite on Nexus, and a compatible skeleton, I recommend this one. (if you're using Enhanced Movement you need to get a compatible first person skeleton too like this one, or the one from this page in it's optional files section)

Dramatic Inertia has a bnb conversion too, and it looks great but the bounce is pretty extreme so there can be a lot more clipping.

Robert S also has a really good animation set that even has it's own actual butt animations but it's made with male bodies in mind and doesn't work very well with the way I handled butt bouncing so the bounce will be really extreme if you use the BB addon. Maybe someday Allnarta will grace us with female animations. I recommend getting it, and removing everything but the animations unless you want the body, and then loading it above your other BNB animations because it has some that other animation mods don't.

Load order:

1. Type 4 body armors

2. This mod, and other type 4 conversions

3. most advanced bnb skeleton last

BNB animations wherever you want

BNB Troubleshooting:

1. Boobs stretching through the universe: You are missing a compatible skeleton; if the skeleton doesn't have breast bones that happens.

2. Boobs/butt stuck after animation ends: this happens if your character goes from a BNB animation to one without it, say your jump has breast bones animated but your idle doesn't, your idle will just inherit the last position from those bones until you use an animation with BNB added again. Solution is just to have more bnb animations.
