Petite to Plenty - A CBPC Config for Realistic Collisions and Physics 8.3

If you play a vanilla-style game of Skyrim, then this is good for you! 

If you dress up sexy dolls in erotic attire, you may prefer the "clothes" parameters to have MORE amplitude! ❤️

Billyy Table Blowjob (stage 5)


Nibbles Face Sitting
this is a cunnilingus animation with the actors switched so the male can be on top. to showcase scrotum collision


I can't remember this animation, sorry.  It is way out of alignment to showcase scrotum collision.

Leito Doggy 2 (stage 1-2)
weight 100 P2P 3BA preset (v8) 

Nibbles Sideways Fuck (Stage 2)

If you experience a flickering anus opening, try downloading the skeleton_female.hkx file

TIP:   For better anus alignment, try using the Bodyslide slider "Anal Back" found at the bottom of Vagina and Anal (3BA)
There will be something similar with BHUNP.

The idea is to move the anus away from the vagina opening. 
Not a whole lot, just about 1 inch (2.5cm)
Setting that to 10%-20% for both weight 0 and 100 will help. 
Try 20% first, and then more or less from there!

I guess other sliders can affect anus position, so 10%-20% might not be enough, or too much.  It'll depend on your preset a bit. 
Just remember it might be easier to move the anus position on your body preset (to match my CBPC anus positioning) than it is to tune anal CBPC values to match your preset.
That's just some friendly advice lol
(tune my CBPC values to your heart's content though!  I encourage that too ❤️ )

Anal collision should be close or bang-on for most presets.

-Weight 0 breast size has been decreased to include more petite-shaped bodies throughout the gradient.  Weight 100 breasts may be the "smallest" of my versions, but making them bigger should be easier than ever (probably just increase sphere sizes by 1 or 2)

-Breast movement is wonderfully distinct at weight 100 and weight 0, not just a linear decrease in movement.  Weight 0 still has plenty of movement range and bounce, but the range is tighter and breasts are lighter.  Weight 100 movement looks heavy; sags, droops, and splays out nicely.  Yet breasts bounce freely and without encumbrance.  
I personally loved v6 movement, and v7 was quite sublime. 
Hopefully v8 will be refreshingly different in almost no noticeable way! haha

I haven't fully solved "breast-drag" with my config yet.  That's when you see breasts behaving undesirably when running, sprinting, jumping, going down stairs, etc.. I've decreased it as much as I can.
The newest 3BA config DOES solve these kinds of issues!  Their CBPConfig_3b.txt is the only file contributing to that fix.
There are A WHOLE BUNCH MORE parameters to tune.
They are all standard instructions, but there are now pretty much every combination of instruction and parameter there can be!
It's totally possible to mash my config and theirs together.
I'm not sure if I'm ever going to get around to incorporating all those parameters into P2P.
Anyone else is highly encouraged to use P2P as their starting point to making a better config for the community!  ❤️

I've added scrotum collision to your game.  v// 

Yes, balls can be cupped in hands, dragged across faces, and slapped against buttholes and pussies. 
*caveats included* 

My goodness. 
Its not perfect, but its a start!

Scrotum node can collide with a bunch of stuff now and doesn't just float through thighs and other body parts!  It will clip through male thighs a bit, and I couldn't quite get vagina/labia/clit collision working good enough to enable, BUT, collision with female thighs does seem to be adequate to prevent pussy clipping for animations like doggy style.
This is new and experimental. 
Within CBPCMasterConfig_SOSScroum.txt are two references for the scrotum bone. 
3BA and BHUNP mods put a hashtag in front of the first reference, so the contents of their file looks like this:

[ConfigMap]                   
#NPC GenitalsScrotum [GenScrot]=SOSScrotum
GenitalsScrotumLag=SOSScrotum

I remove that hashtag in order for scrotum collision to be enabled.  I don't know why that is.  
To disable scrotum collision, just put the hashtag back! 
This might cause problems for some people, and I wont be sure until a bunch of people tell me so.

Other than that, scrotum collision is great!  Doesn't work amazingly well in all situations. ie. there's a missing patch of collision in the female pelvis region, scrotum collision is pretty conservative and soft and should clip through some body parts a bit (intentionally), and some of this collision accuracy is to be determined by you! (as you are my guinee pigs lol)

Enjoy! 
and feedback on scrotum collision would be helpful, please!

I've completely customized what can and cannot collide with almost every female node.  I've also added a couple nodes.  And a scrotum collision node for males!
At the top of CBPCollisionConfig_Female.txt you will find the [AffectedNodes] list.  In the list are a bunch of nodes, and beside them (in brackets) a list of some more nodes.  Those nodes in brackets will not be able to affect the node they are listed beside (unless there's an "@" symbol in front of the node name.  the "@" symbol is like a hashtag but only for the one node, not everything after that node)

This is the biggest change to P2P, by far. 
Why?
This affects all collisions and almost all nodes. It fixes many oddities and tries to simplify the tuning process!  

This customizes the [AffectedNodes] list (for better or for worse). 

A great example to help explain = boob jobs should work flawlessly now. 
Why?  Because I've disabled breast collision with penis nodes!  Nice and simple.
You are certainly capable of tinkering the shit out of all of this yourself.  Nothing here is set in stone 


-Anal node collides with ONLY penis nodes now! 
no more random anus opening (from the pelvis) or fingers or hands!  no more head triggering anus opening during cunnilingus!
Right index finger (finger 12) DOES collide with Anal node (i let it.. its the only non-penis node that does, i think) just for literally one animation (I can't even remember what animation it is lol).  You can easily disable by reading the prompt directly below the [Anal] node found at the bottom of the [AffectedNodes] list found in in CBPCollisionConfig_Female.txt 

-Heads do NOT trigger vagina opening or labia collision anymore! (maybe that's good!  maybe not, maybe you liked that.  let me know.  easy to change back if you want) 

-Some fingers no longer collide with female genital nodes.  (hopefully a better experience than V7, but I'm not actually sure if it will be. V7 was great)

-Some fingers do not collide with breasts anymore.. this was done in an attempt to further wrangle breast collision. 
Breast collision is something I'm a little worried about because I feel its been degraded a bit by the whole ordeal.  But I'll let everyone else be the judge.  Bewbie collision still works fine, but maybe previous versions were as good as it gets and I'm chasing that here with V8.

Something I've learned, is essentially, you get body part trembles/tremors and erratic movements when too many nodes are colliding at once with a particular node.  This is a common problem with butt nodes and breast nodes.  I've done my best to control what can collide with them so as to limit the amount of interactions that can occur.  This has helped in a bunch of the animations I test (especially butt nodes!) but also degrades some of the collision experiences in other animations. 

I'll let everybody decide for themselves if they prefer breast collision in V7 or V8.



BE AWARE, if you want to manually copy/paste collision values from other configs or other versions of P2P into V8 (or use V8's collision values in other configs), you will also have to copy over the respective  [AffectedNodes] list! (or try to cobble shit together however works best for you)
The [AffectedNodes] list in V8 is customized, and likely is different from all other configs, so probably won't have the same effect with other config's collision values.  It might be fine, and so trying without copying the list over won't hurt anything at all.

It wasn't my intention to make things more difficult to incorporate other configs.
srry ❤️

to increase ass-smashing goodness back to 8.1 levels, simply move male pelvis "outwards" 
look into the spoiler below:
 

Ass-smashing goodness headed your way, and so you're welcome
sex animation below

Leito Anal Doggy 2
weight 0 P2P 3BA preset (v8)
Hands should be able to spread butt cheeks apart! *(limitations here, but yeah, hands move butt cheeks in a particular direction!)
so have fun with that too

Butt movement has much more room to increase it's amplitude value found in CBPConfig_ButtAmplitude.txt
so if you want even more butt movement you can add it yourself and hopefully limit the tuning you have to do (maybe no tuning!)

Rear thighs have also been given some attention.  They're still very conservative with collision and movement.

I've disabled the penis nodes from being able to affect breasts!  Schlongs happily sit in between, never causing any troubles!
I would still highly suggest using NiOverride Pose Adjustments + Objects SE for control of both female and male positioning.
sex animation below
 
Boobs play nicely with PP's!
Weight 100 3BA, version 8

So like, V7.1 labia/vagina/clit collision was pretty great.  I THINK* v8 is an improvement..?  It might not be for some people?  I have no idea lol.
It'll be very close in terms of functionality.
Anyone new to downloading P2P wont be missing out on V7.1 labia/vagina/clit collisions. (i encourage you to try V7.1 if you aren't satisfied with V8)

I'm wondering, will users of V7.1 enjoy upgrading to V8?  I really don't know!

I think there is more movement.. female genitals are more reactive to collisions. Vagina opens a bit more and its movement increased... i hope collision sphere placement is okay.  Clit moves quite a bit more i think.  

3BA, wide-opening option.  Below is V8
A reasonable amount of natural movement is intended



3BA, wide-opening option.  Below is V7.1  

I'm pretty confident there is much less twitching of the labia, freaking-out vagina opening, and odd vagina collisions!.. 95% of the time!
I can't get rid of ALL the weirdness ALL the time, but for 95% of the time it's pretty much flawless.
Vagina/labia opening should also slightly scale with penis size!  It's not as much as I would like, thus there are two vagina-opening options in the FOMOD.  The narrow option might be a bit more suitable for BHUNP users.

PLEASE, ALWAYS let me know if vagina/anus collision is interfering with each other in unreasonable ways! 

I want to mention this functionality was introduced by Shizof in their CBPC mod long ago (not by me lol).  I'm just sharing how to utilize it!!

This is a great way to customize your experience and enable some improvements which is only possible from your end.
Say for example, you play with futanari characters.  It would be most optimal to give penis collision spheres to ONLY the character's with schlongs!  Instead of ALL females, which is what my FOMOD option does. 
Below will explain an improved way to enable futanari collision!

- To start, copy CBPCollisionConfig_Female.txt 

- Next, rename it something you'll remember; it can be named anything.
eg. CBPCollisionConfig_Female_Renee.txt  -or-  CBPCollisionConfig_ReneeFutanari.txt   -or-  CBPCollisionConfig_MyCharacter.txt

- Open your new file up and at the top you will see
[Options]
Conditions = IsFemale()
Priority = 20 

-  Change the condition to something like:  ActorName(Renee)  -or-  IsUnique(YOUR CHCARCTER'S NAME)  -or-  IsRaceName(Nord)
(For a full list of the available condition functions refer to the text file itself, at the very top in the "Conditions" box written up by Shizof right from the beginning)

-  Then change the priority to = 100

-  Lastly, head to the very bottom of the file and remove the hashtags from the beginning of the two nodes and their values underneith! 
(So they look like this)

This now enables futanari collision in this specific text file without it affecting ALL females in the process!  

This is not exclusive to futanari collisions at all. 
In fact, you can make a custom config for any NPC/group of NPC's with almost every text file, including all the movement files for breast, butt, vagina, etc..

Simply rename my (or anyone's) set of config files to something of your choosing (like the above samples) and then apply your choice of condition options with a higher priority than my base config!  Some examples would be:

CBPConfig_3b_Renee.txt   (This file controls breast movement and some breast collision behavior.  In this example it's for a specific NPC named Renee) 

CBPCollisionConfig_BigButtBertha.txt    (This is a collision file for a potential follower that may or may not exist, with an exceptionally large caboose.  You may desire a different set of collision sphere values for this NPC compared to their less curvy peers.  You can customize ANY node's collision values inside this text file, not just butt spheres!  Probably even the [AffectedNodes] list!)

CBPConfig_vagina_FistingOpening.txt   (I'm just making this up on the spot.  But it is technically possible to make a set of config files for a particular NPC or your own character, which would include a customized vagina config file like this one, and could enable enormous openings and even forearm collision with labia/vagina nodes for something like fisting! 

Now technically you would need to find (or make) some fisting animations!  Or maybe VR users could figure something out..
But this is all just some brainstorming and food for thought to describe the possibilities!)

I believe even the amplitude files and gravity files have this Conditional functionality. 
If the text file doesn't have an [Options] section at the top of it, just add one yourself
 

You may find that your hands are far away from weight 100 breasts, but collision is triggered.  In this case the collision spheres are larger than your preset's breast shape, and you will want to shrink the weight 100 collision spheres, or increase your preset's breast size at weight 100.
The opposite may also be experienced, and you may find your hands moving through the breasts too much.  That would mean your breasts are larger than my collision spheres.

I will explain how to decrease the collision sphere sizes so you can try and match the collision spheres to your preset yourself.
Increasing values is just the opposite of what I'll be describing below!

Open up CBPCollisionConfig_Female.txt and locate: 

What you are looking at are strings of 4 numbers, with a " | " separating 2 strings.  The 1st string is weight 0, the second string is weight 100 values
The first three numbers represent coordinates (x, y, and z) and the fourth number defines a radius for a sphere.
The coordinates move a point associated to a bone (in this case, the 3 breast bones) to what ever values you set, and then the radius gives the point volume.
So in English, the non-sense of numbers actually looks like this:

[L Breast01]
[weight 0] x-coordinate, y-coordinate, z-coordinate, sphere size  |  [weight 100] x-coordinate, y-coordinate, z-coordinate, sphere size

Breast01 affects the chest and base of breasts. 
Breast02 affects the main mass of the breast. 
Breast03 is basically the nipples (and nipple area).

FOR BREASTS this is how the points move according to coordinate values:
The X-coordinate values moves the point left and right.  Positive values move in the direction of the right arm, and negative values move in the direction of the left arm.
Y-coordinate moves point in/out.  So positive values move in the direction toes point (lol) and negative values move in to chest and towards heels
Z-coordinate moves point up/down.  Positive moves up, negative values move down.

For starters, you can try to reduce the size of the 4th value for all the weight 100 strings.  That would mean reducing the sphere sizes only.
But it might also be beneficial to bring the spheres up (increase z-coordinate in positive direction), and bring spheres closer to chest (so change y-coordinate values towards negative direction).
A change by 1 or 1.5 for is probably enough.  More or less is fine too!
Try copy/pasting the below values to see if they work for you.
Try to spot the differences and you will understand a little better.

Here are some values that work for larger breasts (possibly) made by LBmtFodaa and shared with everyone in the posts tab!
Give them some kudos if they work out nicely for you! 
Just copy/paste and see what happens!

- You can edit breast movement by opening CBPConfig_BreastAmplitude.txt.  
1st value is weight 100
2nd value is weight 0
Increase values to increase movement, and vice versa.

- There are more advanced parameters to tune within CBPConfig_3b.txt


- .stiffness + .stiffness2 and .damping are all fundamental parameters that should be tuned first, and then tune everything else after.  That's not how it HAS to be done, but I suggest following that advice at first, and then straying from it later. 
These control breast bounce (or what ever node you're tuning).  Stiffness is how fast the bounce is, and damping determines for how long the bounce can keep oscillating.  High values of stiffness should be paired with a high damping value, and low values of stiffness should be accompanied by a low damping value.  Once again, that's not how it HAS to be.  This is all harmless advice to keep things simple.


- .minoffset and .maxoffset
I am unable to define exactly how these work.  They determine maximum movement range and sometimes permanent positioning.
Don't fuck with these unless you're willing to go down a serious rabbit hole of, "WTF IS GOING ON?!?" 
You can break node movement with the wrong values!
I don't even know what the "right" values are.  mine are the result of relentless and extensive testing.  like 100's of hours probably.
Mine still might be wrong lol




- .timetick and .timeStep can be useful for slowing down or speeding up breast movement.  Change .timetick in increments of 1 to see any difference.
.timeStep should be tuned by increments of about 0.1, but change it by a good amount at first to see what kind of difference it makes.

Apparently these should be set according to the FPS you plan on playing your game at.
(or at the least, they are tied to your FPS is an important way).  
You can make one of these redundant by going into CBPCSystem.ini and setting FpsCorrection = 1

If you find breast movement is choppy or doesn't move in an expected way, try messing with these a bit.




- .linear(X,Y,Z) will control "kinda like the amplitude" of the movement effects.  Higher values cause more movement (to extreme levels even), smaller
values dampen movement and movement range. 
Breast1 + 2 "Y" parameters will affect how much breasts droop when bent over and how much they sink when laying back.
Breast1 + 2 "Z" parameters will affect the height at which breasts will lift and sag when jumping, running, sprinting, etc...


- .rotation(X,Y,Z) will control the rotational amplitude of the node. 
These need very small values to attain the desired effect!
You can mess around with these for some good laughs haha


.linearZrotation(X,Y) controls something related to rotations..  lol sorry I'm not really sure either
Hit up tuning mode and plug in some numbers and see what happens!


.linear(X,Y,Z)spreadforce(X,Z) is another parameter that I'm not really sure how to explain or define.  I don't use much of it.  Explore!


.collisionFriction is an important parameter for collision.  It controls how much this node wants to "stick" to other colliding nodes.  
So higher values mean breasts will want to stick to hands or arms or whatever else may be colliding with them with a stronger affinity.
Low values mean hands and other body parts will graze past breasts and wont "drag" breasts along with them as much.


.collisionElastic is kinda like how much the node wants to spring back to it's "non-colliding" position.
Low values means it wants to spring back very quickly.  High values means it'll spring back at a more leisurely pace. 


- .collisionPenetration is great for a lot of different reasons.  It can be found in almost all the configs.  It controls how sensitive spheres are to reacting with other spheres.  A value of zero means as soon as spheres makes contact with another sphere, collision is triggered.  Higher values allow spheres (seemingly) to overlap/penetrate each other and possibly soften the effects of collisions.   Very helpful for making touching things a softer experience!


- .collision(coordinate)(max/min)offset does what it sounds like.  Determines the min and max distance in certain directions the bone can move when colliding with other spheres.  This could actually be tuned more extensively by anyone.

- You can edit butt movement by opening CBPConfig_ButtAmplitude.txt.  
1st value is weight 100
2nd value is weight 0

Increase values to increase movement, and vice versa.

- There are more advanced parameters to tune within CBPConfig_butt.txt

FOR BUTT this is how the points move according to coordinate values (same as breasts)
The X-coordinate values moves the point left and right.  Positive values move in the direction of the right leg, and negative values move in the direction of the left leg.
Y-coordinate moves point in/out.  So positive values move in the direction toes point (lol) and negative values move in to chest and towards heels
Z-coordinate moves point up/down.  Positive moves up, negative values move down.


Refer to breast movement and the parameter "definitions" there as they apply exactly the same to butt movement.

to increase ass-smashing goodness back to 8.1 levels, simply move male pelvis "outwards" 
look into the spoiler below:

- The easiest way to decrease labia opening is to open up CBPConfig_vagina.txt and decrease the Labia.collisionMultipler
I've set the values to 4.5, try 3 and 3 (both left and right labia parameters!)

This is also a reasonable way to increase the labia opening.
Increasing this beyond some value may exaggerate undesirable labia motions.   
But you could probably go up to 6 before anything crazy starts happening.

To increase labia opening even more, try the below methods:

- Slightly increasing Labia.collisionMultipleir (by about 1 or 2), along with slightly decreasing Labia.collisionPenetration (by about 0.1 or 0.2) will help balance out the negative side effects associated with each  (remember to alter BOTH left and right parameters!)
Also, open up CBPCollisionConfig_Female.txt and edit theses values:
 

so they look like this:

 

All I've done is slightly increased the x-coordinate values, moving the collision spheres towards each other (closer to the center of the vagina opening)
The effect is it widens labia opening.  The combination of these 3 parameters and the slight changes to them should preserve pleasant movement, but also facilitate increasing the labia parting to obnoxious sizes (probably).

- To increase/decrease the vagina opening in the "up/down" direction *(?) (like, opens more towards anus) you will want to open up CBPConfig_vagina.txt
and then find VaginaB.collisionMultipler 3
Try 3.5 or 4 for larger openings, try 2 or 1.5 for smaller openings

- If you'd like to scale back clit movement, look in CBPConfig_vagina.txt and find

Clit.collisionMultipler 4.82 

Reduce to maybe 2.5 and see if that's enough for yourself.

- Some people may notice some erratic vagina/clitorus movement.  A way to reduce this is to go into CBPCollisionConfig_Female.txt and find
[VaginaB1] and [Clitoral1].  Place a hashtag (#) in front of each and their corresponding values underneath so they look like:

#[VaginaB1]
#0,2,1,0.5 | 0,2,1,0.5
#[Clitoral1]
#-0.1,3,-1.1,2.2 | -0.1,3,-1.1,2.2

That may help with smoother vagina movements. 
I keep them enabled for the extra movement.  Adds a bit of depth.  Sometimes they don't behave nicely though.


- Maybe you would like V7.1 genital collisions instead of V8, but you want V8 everything else. 

In that case, simply replace V8's CBPConfig_vagina.txt with V7.1's

If you would like to be exact about it, you would also go into CBPCollisionConfig_Female.txt and do the same with the labia/vagina/clitoral/anal nodes. 
As well as the male genitals in CBPCollisionConfig.txt 

Within CBPCollisionConfig_Female.txt are AnusOpeningMultiplier and AnusOpeningLimit.
You can change these values to your liking.  Increase values for larger opening, and vice versa.

If you'd like to turn off anus collision, simply change the values to 0.

If you experience a flickering anus opening, try downloading the skeleton_female.hkx file

TIP:   
 For better anus alignment, try using the Bodyslide slider "Anal Back" found at the bottom of Vagina and Anal (3BA)
There will be something similar with BHUNP. 

Setting that to 10%-20% for both weight 0 and 100 will help. 
The idea is to move the anus away from the vagina opening. 
Not a whole lot, just about 1 inch (2.5 cm)
Try 20% first, and then more or less from there!

- Belly movement  in my config is enabled by default.
You can disable by opening CBPCMasterConfig.txt, and at the bottom of the file, add a hashtag
at the front of:   HDT Belly=Belly=IsFemale()   so it looks like this:   #HDT Belly=Belly=IsFemale()
maybe, also try adding the hashtags within CBPCMasterConfig_3BA.txt as well!

-Belly collision in my config is disabled by default. (belly bulge off by default)
You can enable again by going in CBPCollisionConfig_Female.txt and removing the hashtags from 
#[NPC Spine1 [Spn1]], #[NPC Belly], and #[HDT Belly] (as well as the hashtags from the start of the coordinates below the names)

ALSO what's below (found near top of same file) remove hashtag from NPC Belly

[AffectedNodes] 
#NPC Belly (@L Breast01,@L Breast02,@L Breast03,@R Breast01,@R Breast02,@R Breast03,@NPC L Butt,@NPC R Butt,@NPC Genitals01 [Gen01])

I don't think I've tuned these so you're kinda on your own sorry

- I forget why I've disabled #[NPC Pelvis [Pelv]] #For Female Genitals in CBPCMasterConfig.txt and CBPCollisionConfig_Female.txt 
Maybe they're disabled by default. 
What ever the case, if you want those enabled for any reason, you probably already know what you're looking for.
