3BA/3BBB belly and vagina fix/guide

[mcnv]

• Have you just installed 3BA/3BBB and are having issues with the promised vagina and belly physics?
• Do you have a stickler for realism?
• Do you have a fetish?

 

I probably can't help with the last two but:

YOU HAVE COME TO THE RIGHT PLACE

 

I have spent an afternoon trying to fix just that.

This guide or fix will go a roundabout way in helping you through this issue so that if you have more issues it may cover it. it will be divided into three sections: Files, In-game configs, and text configs. Each section will cover possible issues deriving from each

 

PLEASE NOTE: I only use 3BA on MO2 so anything concerning UNP or other mod manager may not be accurate. 

 

Mods mentioned:

SOS

The New Gentlemen

CBBE

3BA

UMP

BHUNP

BAKA'S SOS Patch

ABC

Creature Framework/More Nasty Creatures

Bad dog's hoodies

Petite to plenty CBPC config

Files

here are the relevant files to achieve Physics in Skyrim. 

 

Male Body Penis

SOS

Physics mod: eh... keep reading

Note: The New Gentlemen Does not handle physics.

The vagina might part and the belly might move but that is the result of pelvis collision (a sort of pseudo collision detection via how close the actors' pelvis' are to each other)

 

Female Bodies

Two bodies support Physics:

 

CBBE

Physics mod: 3BA

 

And

 

UMP

Physics mod: BHUNP

 

They are similar but not interchangeable

 

Installation:

This screen exist in BOTH physics mod. Make sure you have Belly on CBPC.

This is because SOS works with CBPC. CBPC physics won't interact with SMP. My efforts in finding an SMP Physics for SOS have not succeeded. 

 

 

 

These screens exist ONLY in 3BA

 

I have no idea what this does but it apparently adds physics to dicks. 

 

The Vagina physics checklist does not exist in BHUNP. For all I know, however, both bodies have vagina Physics. looking at it in body-slide:

 

3BBB

 

BHUNP

There's something there.

 

 

If you can't get regular boob jiggle to work on their own...

STOP.

You did an Oopsie.

READ THE REQUIREMENTS.

INSTALL THE REQUIRED MODS.

 

 

 

ODD SOS

 

here's an odd file

BAKA'S SOS

It's a mod by BAKA which apparently adds SMP collision to three specific shlongs: Smurf average, VectorPlexus muscular and Average.

however, it does not seem to interact with SMP belly. it works on the vagina, but nothing else.
As Baka's patron and their older mods had disappeared, I have managed to find someone else who still had it here:

 

SOS has a file in its page that proports to give SMP collision made by DykkenTomb (using collision branches by cOJzZ and Senpo)

For whatever reason, I dismissed this file while I was trying to solve this years ago, likely because it doesn't work(?). Then I notice a comment on the 3BA nexus page saying that the file had the wrong file structure for it to work properly.

Should the image not show up here are the basic instructions
 

Spoiler

SMP from S.O.S. file Schlongs_of_Skyrim_SE_HDT-SMP - v1.1.rar  "not work" because the installler is incorrect ! It copies MaleSchlong.xml into %GAME FOLDER%\Data\SKSE\hdtSkinnedMeshConfigs\ when it should copy into %GAME FOLDER%\Data\SKSE\Plugins\hdtSkinnedMeshConfigs

So you only need to copy/move the MaleSchlong.xml from %GAME FOLDER%\Data\SKSE\hdtSkinnedMeshConfigs\ into %GAME FOLDER%\Data\SKSE\Plugins\hdtSkinnedMeshConfigs ans then it will work and no need for Baka's files at all.

In-game configs

 

there are three separate MCM menus relevant to belly and vagina collision. look around these:

 

Creature framework

if you use ABC or the animations for it, you will have to set every animal who uses Animal SOS to Animal SOS+ABC to get those animations and dicks to not stretch. it's not as tedious as you may think it is. (unless you're me and start a new game every other boot-up, then you can just ignore it until you encounter something)

 

It has come to my attention that Animal SOS is no longer supported. Just use ABC, Creature Framework, and More Nasty Creatures. This also makes animal parts default to using ABC appendages by default so hopefully you don't have to go here, but if an animal penis isn't animating as advertised by BAKA, check Creature framework's MCM.

 

Shlongs of Skyrim

In testing, I noticed that Smurf average works best for collision. As the average dick is quite short, setting the size of this specific dick to 15-20 seems to be the optimal size to get the belly collision to work.

Any other custom penis, such as Bad dog's hoodies won't work well with the SMP vagina collision but works well enough with the CBPC belly. a dick that is too big would somehow not collide with the stomach so keep it balanced.

 

3BBB

toggling physics. 

 

Text configs

 

for MO2 you can check any test file by right-clicking on Information at the bottom of the popup

go to the text files tab and pick CBPCCollisionConfig.txt like so

 

if you don't use MO2 find the installed mod file and go here

 

I know there are explanations in the text but it's lacking.

 

eldr3d linked to a complex breakdown of the physics settings. If you want to read more.

 

Here's the quick rundown:

 

BellyBulge 

this is the number that controls at what rate the stomach will bulge.

Smaller numbers make smoother presentation, while higher numbers increase bulge sensitivity. 

try increasing by 0.5 each time.

 

BellyBulgeMax 

this is the number that dictates how big the bulge can get.

50.0 works well but you can increase or decrease it at will.

Please keep in mind it won't bulge like a pregnancy morph. it's like a spike.

 

BellyBulgePosLowest

slightly misleading as it actually sets the bulge to a certain angle.

the higher the number the higher the angle

so instead of a

 straight bulge,

at higher numbers, it is more of a

 long bulge

 

I think. I have no idea really but it definitively moves the bulge up the body instead of down.

 

BellyBulgeReturnTime 

I think it is the time it takes for the bulge to go back to normal but in my testing, it didn't do anything

 

VaginaOpeningMultiplier 

Similar to BellyBulge but for the vagina.

 

I set it around 20.0

 

VaginaOpeningLimit 

BellyBulgeMax but for vagina. HOWEVER, it seems to have an odd quirk where if the numbers get too high or the penis is too long it will not register the collision

 

I set it around 60.0

 

Just know my settings are overkill. 

 

 

Beyond these settings, there's also the Penis collision shape itself at the very bottom of the text files. These are far more complicated than the above settings requiring coordination between the body weight of NPCs and the schlong size set in SOS. So please don't touch them unless you know about collision spheres.

The file explains these numbers.

 

 

eldr3d has their own "realistic" configuration, and a recommendation to try Petite to Plenty - A CBPC Config for Realistic Collisions and Physics - Adult Mods - LoversLab

Note: IF you do use Petite to Plenty, You'll have to enable belly bulge

• go to CBPCollisionConfig_Female.txt go to the line "BELLY BULDGE" follow those instructions and delete those hashtags not seen in this screenshot.
• 

 

Uhon Enej has another configuration along with a few adjustments to collision spheres.

 

Animal SOS

This is a pain

 

You'll notice the names of those files: CBPCCollisionConfig_[animal name].txt. They all contain the same stuff as the one in 3bbb.

 

If you want you can configure the animal SOS and ABC collision files but apparently, they don't do anything.

SOS smp patch apparently not installed correctly? might be a new solution?

[rizlakingsize]

I owe you a beer. SMP just stopped working for me and I was reinstalling and trying all sorts of stuff. Installed Baka's patch and it's sorted. Thanks. I mean that.

[linkhuesitos]

Baka purposely deactivated the belly physics in his SMP config file because he said that it never archieved his target.

You can activate it again by just adding the "Belly" node data into the txt.

what i have to do it again? can you explain it more in details, Thanks in advance

[RetryAgain]

Baka's mod was exactly what I needed, thank you!

[_Snow]

I know this is late, but I've been struggling with CBBE and Bodyslide for a while and when you said "The Vagina physics check list does not exist in BHUNP", it hit me that UNP textures and physics were my biggest issue, or maybe I'm wrong but I deselected all the UNP stuff in Bodyslide and all my problems were fixed. Thank you!

I'm not finding in game the part of the directions that says this

 

Creature framework

oh, yes, I'm on AE. So we will have to wait then for the mod author of ABC to make it compatible with AE?

[Chiyosuke]

Does this work with TRX or CBBE Futanari schlongs?

[AbsoluteOmega]

I'm trying to get the bulge to work in my modded game but whenever i set belly to CBPC it doesn't move. the pysics doesn't affect it and so it' doesn't move. if i se it to SMP then it works but i want the bulge to work

[jameswerder]

I have everything working but man, is there no way to have belly bulge work with SMP?

 

I kinda like how SMP looks in general but when I set to full SMP, including belly, I lose bulge, only works with CBPC.

if the schlong has CBPC Collison it should, theoretically.

So you want your character's belly to jiggle in CBPC I take it? CBPC has simpler physics, maybe its just not strong enough to be noticed. Is everything else working?

Yeah, there have not been much released concerning belly or schlong physics. Ass on the other hand.

the closes thing you can try is this:

i added ninode named "Belly" and even "NPC Belly", none worked!
sos still clips through belly.

So I got belly SMP running, but it's very wonky. I've been fiddling with the settings for two hours now, and nothing gets even close to what CBPC can do, simply because CBPC uses a sort of scripted system that is based on vagina penetration, instead of colliding the dicks with the "belly pillow" like SMP does.

 

To start, you'll need to hide/delete the folder SKSE\Plugins\hdtSkinnedMeshConfigs\ from Animal SOS SE. (I recommend using Broom for that.) These XMLs might be overriding the Baka ABC collision settings, which do not explicitly disable collision with bellies. Then, install my archive like any mod and probably take a look at this to get an idea how to continue tweaking those values.

Disclaimer: My files are based on Animal SOS SE and 3BA (Realistic SMP Physics option in the FOMOD). I did not change much. Anal settings are like Baka left them, I only uncommented these. Belly physics are modified, but probably not a lot better than Baka's.

Hey, Sorry to Necro this Thread, but i can't get for the Life of me the Belly Bulge to work. I have all the requirements installed, when installing 3BA i chose CBPC only, so that to can't be the Issue, everything else (Breast, Butt, Vagina Physics and Collision) work just fine, and i copied the setting you use in the Config Files, still nothing.

 

I'm stupid, i had the Petite to Plenty Config Installed and didn't properly read through the discription.

the others are collision spheres and their header's so they're easier to find

Edited June 27, 2023 by xavier0self

[eldr3d]

I have established these values with a bit of trial and error:
 

BellyBulge=1.25
BellyBulgeMax=35.0
BellyBulgePosLowest=25.0
BellyBulgeReturnTime=0.5 # This did not seem to affect *anything* in my testing.

 

Further, the ABC config files are not relevant for the belly bulge! You don't have to, and actually cannot set different bulges for different creatures, as far as I can tell. My config will however still work pretty well because smaller cocks will distend the belly less (because of the low BellyBulge value) while the max is set rather high to have a somewhat "realistic" proportionality.

I recommend using Petite to Plenty (improves human vagina collision by a LOT) and enabling anal and bulge options, then set the above options in the CBPC_CollisionConfig_Female.txt. (For all 3BA users: this is the only file you need to set this in, because it has a higher priority than CBPC_CollisionConfig.txt.) Petite to Plenty enables all penis-like nodes for belly collision, which makes the bulge work a lot better for some very large cases, although it also means that the belly sometimes bulges when it's not actually inside.

Edit: The author of MNC said that Animal SOS is deprecated and incompatible with newer versions of ABC and MNC, that should maybe be mentioned here as well.

Saving this for when I inevitably need to reinstall Skyrim from scratch again

[Uhon Enej]

Yay! Achieved some decent results using the Petite to Plenty config. Goes up to very large bulge, pushes the belly out preventing clipping and is well synced with movement. Also no more large bulge with small penis.

 

But it took more than changing the Belly Bulge values. Mainly its about editing the NPC Spine1 collision sphere (read the guide for CBPC) and disabling collision with hands (for animations where hands are placed near belly).

 

In CBPCollisionConfig_Female.txt find and change these values:

 

[ExtraOptions]
BellyBulge=1.6
BellyBulgeMax=20.0
BellyBulgePosLowest=10.0

[NPC Spine1 [Spn1]]
0,13,3,8 | 0,13,3,8

 

Result is good for animations where you would normally see clipping through the belly. So far it seems pretty robust and works for most animations (animal animations too).

The physics not working.

 

Does the naked body physics work?

if yes: then it concerns the outfit.

This outfit mod is not made with whatever physics setup you're using. I've seen the mod, it has three different versions for three different body physics mods. Did you use the correct one? If you are: Their fomod has several settings you might want to look over. Try reinstalling those.

 

if not: Then you have a bigger problem. go over the requirements for the mods and the requirements for those requirements.

Just wanted to say thanks for sharing these settings.  Just about perfect in my opinion - a bit of bulge for distortion and to minimize clipping, but not overly bloated.  Also doesn't look like a twitchy stomach seizure. 

 

Beautiful, and have saved the settings so I'll not loose them.  :)

BellyBulgeReturnTime=0.5 # This did not seem to affect *anything* in my testing.

 

Just letting everyone know, the mystery about this setting may be solved. The newest version of CBPC no longer has the above var in its configfiles. Instead it now has this:

 

Quote

BellyBulgeSpeed = 1.0   #This is the speed of belly bulge to return to its original pos.

 

So this may be yet another case of the CBPC dev not understanding his own codebase and writing shit docs. And it only took him a few years to figure out his configfiles shipped with a wrongly named variable that does nothing. Unfortunally the new var and description is even more ambigious than the former: What does "speed" mean? Is higher faster and lower slower, or the other way around? What is the unit of measurement? You guess is as good as mine.
