I do have one question already. What do I do if the "outfit" I try to load only has one nif file? The guide (and every other guide) says that there should be two... one for the light weight, and another for the heavy weight. However, I'm only seeing one for a lot of the Devious Devices.

 

For example, the folder for the nipple clamps from the Devious Devices Expansion only contains HR_NippleClamps01, and when I load it up in OutfitStudio it appears to fit the Light weight.

That's an excellent question! The answer is that it only has one nif file because it only needed one in whatever game it was originally designed for- which means that it will not morph to a new body shape when the player changes weights. This may or may not be "OK" in Skyrim.

 

In the Outfit Studio "Save Project As" dialog box, there is a check-box for "Create High and Low Weight Files" or similar terminology. You need to un-tick that box when you save it if your item has only one nif file. Now for the hard part: many old conversions (e.g. from Oblivion) of clothing/armor items only have one nif file but they really need the high- and low-weight files in order to be fully functional in Skyrim and not clip through the body (or vice-versa). In such cases, you would need to leave the High and Low Weight check-box ticked so that BS will create both nif files for you when you batch-build the outfit, BUT then you will have to use SSEEdit to edit the outfit's plugin file (esp or esm or esl) and change the nif file specification in the Armor Addon for the item from the undifferentiated (single-weight) to the heavy-weight nif. Normally you would just need to add "_1" to the end of the specified nif file name, so (for example) the specified file would change from "torso.nif" to "torso_1.nif. This is very easy to do and you should not be intimidated if this is required for your nipple rings to make them follow the breasts as they grow and shrionk with weight changes.

 

I will go into OS now and get the exact terminology used for the single/double file choice and add this info to my guide so others will not have to wonder about it as you did. Thank you for bringing it up!

I'm glad it was not a silly question! I'm still a bit baffled though... y'see, I tried to do this process earlier following another guide, and the result was that in-game, the position of the clamps did not move at all when I changed the character's weight. When I exported the nif, I had adjusted them to fit the heavy version of the body. In-game they looked fine; the position was off a little, but it lined up pretty well when she was at 100 weight. But then when I set her to 35 weight, the clamps were hovering away from her tits again. x.x

Yes, this is a positive indication that you do need to rebuild the item(s) and tick the "High/Low Weight Output" box in BodySlide AND edit the plugin so the game will actually use the high and low weight nifs you just created.

 

I just added this as IMPORTANT NOTE at the bottom of my guide, please read it and see if it clarifies things for you.

These instructions seem super clear. :3 I'll give this another shot later, when I have time. Thanks for the help! ❤️

I think that what noreg says is no problem is simply that CBPC does not handle separate physics for weight 0 to 100, if it handles collisions but not physical ones, I don't know if I explain myself correctly but I think it is so.?

So I have bit of a not really a problem. Few pages back in this thread I saw a video of the boobs being affected by gravity even during "crawling" and "upside down" animations and I cant't quite replicate it. When walking around everything seems to be going just fine but during various animations when the character gets on all for or upside down the boobs don't really "hang" how you would expect them to. They still jiggle so physics seem to be working. I also use SMP for cloth physics (body is done by CBPC) and my SMP hairstyle behaves how one would expect it to when doing a handstand as you can see in the screens but boobs stay in default position and only jiggle when I try to move the character. So which settings in CBPC should I adjust to get the desired result or is it even possible with CBPC?

 

Here is what I am trying to achieve. https://static.loverslab.com/uploads/monthly_2019_10/214452610_TheElderScrollsVSkyrimSpecialEdition2019_10.02-20_37_53_03.mp4.981e4d77b15413ff13858d7fb340de64.mp4

In CBPConfig, you can try increasing Breast.linearZ (Scale of the up down movement) value and Breast.maxoffset (Limit of movement). Increase them to absurd values first to see that it works, and then adjust them according to your desires.

[greenmango12]

I sometimes think same thing about CBPC physics effect to move along gravity.  I can see, breast move along body movements,

(eg jump or run, so it move with inertia. and dumping)

 

but not clear see,  gravity effect the mesh. between change pose. At current I play with 3BBB body (all CBPC option install)) , then it offer CBPConfig_3b.txt  for 3 extra bone breast CBPC setting. 

 

There are "gravityBias ", and gravityCorrection values. for all 3 breast node.

but I can not find, discribe (comment) about these 2. the "gravityBias"  value unit is 0.001 etc,, so it seems very sensitve values.a

and I do not know clear, how gravityCorrection will be used to circulate. 

 

  so set more gravityBias, should easy go down to gravity direction (to the ground)

without posing,  from zero postion (of current bone ) of mesh.  right?  Then up-down movement linearZ may effect both direction,

after circulate bravity Bias ?  ( I sometimes feel difficult, those X Y Z axis are local of root figure node, or world axis?)

if it is mesh local axis,, maybe change Z only effect, the bone local Z direction. berast UP-down. not along world up-down.

Yes. gravityBias can be used to simulate gravity. It's applied to the force when calculating spring force. So using gravityBias, it is possible to make breasts sag more. gravityCorrection is used for both applying gravity effect and to correct the calculated and clamped difference value in the end according to gravity.

[greenmango12]

Thanks, so simply up gravitycorrection, may add more gravity along to the gravity force direction about final circulated position of each vertex?

the unit seems 0.1 ,

 

btw the CBBE 3bbb special (with full physics)  mod author offered setting file seems very well tuned about CBPC. 

 

because ,breast 1 = 0.33  breast 2 = 0.1 but breast 3 (nipple area, Isuppose), = 0.03. then nipple may not easy down with Gravity ^^

 

Then all XYZ of config file is object space. or world space?  or it change with each parameter? (sorry double question,, it may change effect much,,

if I do not clear udnerstand,, I supposed all XYZ should be body or the node bone local,,, from discription,

X = side-side Y = front-back, Z =up-down.. axis,,,so it seems bone local unit,, right?   (if all bone have same local axis,, it may be same as object local)

Played around with those settings, and while they increased how high or low the breasts go they still always end up in the default "no movement whatsoever" position instead of staying how would you expect them to behave. Basically it seems that they are not affected by gravity at all, just movement. I tried switching to HDT SMP and it seems to be working but its hard to tell since the default "jiggle" values are rather low and the confing is confusing as hell. Could t be caused by the type of body I use? I am currently using CBBE SE body and building the CBBE Special body in Bodyslide.

Yeah you need to use gravityBias and gravityCorrection to add more gravity and then change linear XYZ and maxoffset if needed.

Linear XYZ are local(object) space.

 

I'm rewriting the bounce system in CBPC 2.0 too. Currently it uses the same bounce calculations as CBP. I'm hoping to make it more powerful as well as make it easier to configure as you wish.

 I suppose half of CBPC user (or more) may not find these 2 gravity related parameters. even though you tweak config often.

 

XXX(mapped node name).gravityBias =

XXX.gravityCorrection =

 

because I had installed a few config files which offered,, but they did not discribe these 2 gravity parameters.

 

After all,  you can just add new 2 parameter, in your CBPConfig.txt. about each mapped node which you want change gravity effect.

 

CBBEspecial, only need one CBPConfig.txt, then NPC L and R breast bones are set as in CBPCMasterConfig.txt ,as Breast.

so,, if I tweak breast physcis gravity for CBBEspecial,, ,, add them  in CBPConfig.txt  around berast node setting.

 

Tuning.rate 60.0000 

 

Breast.gravityBias 0.01

Breast.gravityCorrection 0.35

  

Breast.linearX 2.3100 
Breast.linearY 0.3200 
Breast.linearZ 1.1900 
Breast.maxoffset 3.0000 
Breast.rotational 0.0600 
Breast.damping 0.0500 
Breast.stiffness 0.0100 
Breast.stiffness2 0.0300 
Breast.timeStep 0.8584 

 

 

Then  as Shizof said,, if I only edit these gravity parameter, of config,,  I could not see clear  how those 2 parameter work,,

may need to test with  maxoffset value.

 

(I still not clear how both gravity values but,, I hope to know default value. for both parameter, and gravitybias is difficult word for me,,

so it is anti gravity,, or simply add more gravity? maybe plus value for gravity?  and Correction value is multipled or added (plus or minus?)  

maybe need more user test,, but apreciate  if show simple formula,, how these gravity value will be circulated,, )

 

 Shizof,, I am very looking foward next version and your guide, thanks you still enhance this new physics system. 

 

[greenmango12]

Yes it work,, I hesitate to set large value,, but if I set Breast.gravityBias 0.01 to 1.00

I see like this,, and it work while posing (I rotate root ),, alog with gravity mesh change( about breast)

like this pic.

 

About this case, I only tweak Breast.gravityBias , in usuall sanding pose,, and reverse pose,, breast drastically

move down to the ground..

 

So Breast.gravityBias is first option when you test.. (but we like breast against gravity,,, did not we ^^;?)

 

[greenmango12]

I feel,, up-date config in game ( tuning rate,)  about gravity seems somehow difficult,, it not quick adjust. even though I set Tuning.rate 60, I afraid if it is ovverwitten other Config.txt tuning  rate..  we may only set it when we need test,, so basically I set tuning.rate as 0 for main CBPConfig.txt

 

(about me,, there are 3 CBPconfig.txt for new added body part (3BBB offered), then each Config discribe Tuning.rate. so it may cause matter,maybe set same value no issue. 

 

 

[greenmango12]

Then you should not set too large value, for breast.gravityBias, it work even though you set as around 0.005 I suppose 0.01 may be good enough

to see change..with keep maxoffset around 8 

 

I just set too high value to clear see,, how it work. (as 1.00),, with keep large max offset (in my file, I set as around 10)

 need to set both value (gravityBias and maxoffset  to clear enhance gravity,,)

 

[greenmango12]

mmm,, I hope to up-load wmv,, but I can not,, is it format matter? 

 

[greenmango12]

Then rotate same animation, to see gravity effect clear, I suppose it work reasonable,, so breast shape change along posing and gravity direction.

And I afraid,, if your cloth and reference-body  already have weight for CBP compatible?

 

About CBBE special,,, it should show reasonable gravity effect, if you adjust CBPConfig, correctly.

only diffrence around breast is 3 bone or 1 bone.. but a full phsycs as breast lamp, (deform along to gravity may work, if you can see reasonable shaking  or jiggling already with your shiftness value)  (eg use sinful pop star preset,,)

 

[Guest]

Interestingly, it all already exists and you make it again?

Author mod has already adjusted and calculated the weight and gravity.

Nothing is adjusted here in the video

[greenmango12]

As for me I found, my body is not so heavy (or dream girl) breast  body, so the default 3BBB cbbp setting may weak about gravity.

and I did not covnert cloth body for 3bbb still, but 3bbb rig is already compatible about CBBE special (or new smp)

so it use CBPConfig.txt

 

but what I told to yourself ek is,,  if I remove those 2 gravity parameter, 3BBB author already offered,

and default CBBE special (not new smp ) which yourself ek currently using body

may not offer any gravity parameter, as default.

 if user only use CBBE special, with configfiles here or there ,,  you may not find those 2 parameter about gravity.

and those effect becom too weak or disappear..

 

I actually tested with CBPConfig.txt which I have used, it almost not show gravity physics for me.

but if I add 2 parameter of gravity, it suddenly show for CBBEspecial too. so same procedure may work for anyone

who may not use 3BBB offer config file.

 

 

 

 

 

[greenmango12]

Then Kokan,, so what you means, it is aleady exit ?  it exist in CBBE soecial or CBBE SMP body  setting files,

which currently  "yourself ek" is choosing?

 

I have never seen any CBPConfig files,whch show these gravity parameter. untill I downlaod 3BBB body and author offered one.

or you aldaredy found those, then set-up as you like ,, and it is so usuall parameter for "you" with your custom bodys?

Everything is available for CBBE, I do not see a problem with using it, when I can successfully use that I am a UUNP user.

CBBE 3BBB(3 Breast Bone Body) v1.6.3, CLAMS OF SKYRIM PROJECT Inni Outie HDT Vagina, CBBE-SMP, CBPC....

 

My CBBE follower

[greenmango12]

So Kokan, you everytime miss understanding,, when we talk about defaualt CBBE special or CBBE smp body ,

 

you seems talk about custom CBBE body which other modder offered. (lke 3BBB offer config, and body)

 or CLAMS OF SKYRIM PROJECT etc etc..

 

Please listen or check what other users are talking about now..

 

I apreciate,, all your effort or your work about physics thing,,  but I really think

you too concentrate those custom body which others offered,  and push others to use it,,

But no one say,, "there is no CBBE body, with full physics"  so it is good, if  you like those custom CBBE body, or

you like to introduce others,

 

But now  we just talking about how can adjust good physics,with use CBPC offer parameters.

 

so if I talk about those CBBE custom body only,, I do not say, there is no parameter about gravity etc. actually I said so.

but now we had talked about CBBE special (or physics) body,, which we can download from nexus, as CBBE official.

so if we choose the CBBE special , most of user may not find CBPConfig. which discribed those 2 gravity parameters.

 

I now test those values with CBBE special only . (there is no 3 bones or no collision mesh cover body, and as default no weight for Belly)

just because, it is asked by others.   yes I may prefer, you, download 3BBB , it is gogeous, and work well with default setting.

 

But actually you must see more good gravity with more slim shape. if you tweak gravity values.

then at least I hope to know, how each parameter work more clear.. so it is not matter,

as default it work for someone, or not work for someone,, important thing is, to understand how free tweak those parameter

for each shape.. like your too big breast shape. or more slim shape.
