Is there a creator that makes CC clothing based on this particular bodyshape/slider set?

I don’t think so. Most creators focus on the default top mesh or the EVE mesh. I tried making some stuff with this one, but I don’t have enough patience to figure out how to use Blender.

Help, when I put this mod on, the male sims become invisible and I can't interact with them, what do I do? :C

[Opshuva001]

amazing!!!!!

[Wololo1234]

Guys, i'm getting crazy.

 

I tried the suggested mods but I still get no nipples. I honestly don't KNOW what I need or what I lack. I have the skin mod. It just doesn't work.

 

Could someone please post a requirement list of what I need for this to work?

[lovethreelovefree]

after the most recent WW update (7/4/2025), has anyone else had strange geometry on breasts with this mod? the lower half is suddenly sharp and jagged; i'm going to troubleshoot further, see if it's another mod interaction than just this and WW but I only noticed it after the update

I'm pretty sure you need an overlay, at least that's how I do it.

Hello!

I am having issues with this mod as when it is installed my male sims become invisible?????

Is there any conflicting mods I should be aware of.

I tried removing a few other female body mods and they don't seem to be conflicting.

Also sorry if this has already been posted I cant figure out how to work this website properly

[Sims 4] Heavy Boobs

View File

---

Heavy Boobs is a collection of mods designed to increase the maximum size of breasts and improve their appearance.  It's primarily a slider mod, meaning it affects every outfit of every female Sim in the game.  Secondly, this mod adjusts several clothing meshes and adds some detail options.  The goal of Heavy Boobs is to give larger breasts a more weighty appearance; having them sag a bit with rounded undersides as well as adding indications of nipples poking into thinner fabric.

 

 

Installation

 

Heavy Boobs  Delete all files from previous versions, then drag the Heavy Boobs folder into your Mods folder.  See the spoiler below for details on the Options folder.

 

Navels  Delete all files from previous versions, then drag the Navels folder into your Mods folder.  See the spoiler below for DLC requirements.

 

Mia  Drag the files from Mia.zip into the Tray folder, which is in the same location as your Mods folder.  See the spoiler below for additional requirements.

Base

• HB Slider - Override.  The CAS breast slider mod.  Changes breast proportions to be fuller, and significantly larger overall
• HB Nude Default Top - Override.  Custom high-poly nude mesh w/ nipples
• HB Cleavage Overlay - CAS standalone.  Cleavage overlays designed to accommodate larger, heavier breasts.  User trunnk made some additional swatches

 

• [BG] Bikini - Override.  Custom mesh with improved shape and added nipple impressions. Includes touched-up textures
• [BG] Bra - Override.  Custom mesh with improved shape and added nipple impressions
• [BG] Tank Top - Added CAS swatch.  Custom mesh with added nipple impressions. Custom textures to remove transparent undershirt
• [BG] Low Neckline Tank - CAS standalone.  Custom mesh with improved shape for the base game tank top with a low neckline.  Includes touched-up textures

My own Navels mod, available here

Female Waist and Hip Height Slider by Hellfrozeover

Shoulder Height Slider by Hellfrozeover

FAQ

  Reveal hidden contents

"Help! This mod doesn't appear to be working in my game!"

The meshes are only available at LOD 0, which means you will only see them at the highest "Sim Detail" setting.  If you still aren't seeing all or part of this mod, odds are good you have a conflicting mod.

 

"Is this mod compatible with [popular mod]?"

Not if that mod does the same thing this one does.  Any mod that adds nipples to the default nude mesh is overriding the same file as HB Nude Default Top and will conflict.  Any mod that modifies the breast slider is overriding the same file as HB Slider and will conflict.

 

"What happens when mods conflict?"

When two mods modify the same resource the game will only use the last file it loads and discards the other.  The game will not crash or even produce an error in most cases; the only indication you will have that there is a conflict is that the mod simply doesn't appear in the game.  This can be particularly difficult to spot when you don't know what a mod looks like, or when two mods look very similar as is the case with most nude top replacements.

 

"How can I test for a conflict?"

Temporarily Set all mods but this one aside and load the game with only Heavy Boobs in your Mods folder.  If it works, then you have a conflict somewhere.

 

"Ok so I have a conflicting mod.  But I have hundreds of mods, how do I know which one is causing the conflict?"

I recommend adding your old mods back into your mods folder one half at a time and loading up the game to test.  If Heavy Boobs still works you know it's not in that chunk of mods, if it breaks you know there's at least one conflict in that half.  Once you have a chunk of mods you know contains a conflict keep cutting the loaded mods in half until you narrow down the culprit.

 

"I have a conflicting mod but I love that mod. Can I still use it?"

Sure! My mods are far from perfect and may not be to your liking.  Just delete the relevant file from my mod and keep the mod you prefer.  My slider mod will affect other meshes, and my meshes will be affected by other slider mods.

 

"I have bumps where the nipples should be, but no nipples!"

My mods only include meshes.  You need textures!  I recommend wild_guy's Female Body Details and luumia's Smoothish II skin.

 

 

Complications

  Reveal hidden contents

This mod makes Sims' breasts larger.  Unfortunately, the mechanics of how exactly that effect is achieved aren't so simple.

 

What's really happening is that this mod multiplies the effect the CAS Breast Size slider has on a Sim's figure.  It doesn't extend the slider to go to 300%, it's makes 100% is 3x larger.  This means that every female Sim in the game will become noticeably more endowed.

 

Whether that's a problem is up to personal taste, but it leads into another problem: mesh deformation.  Almost none of EA's meshes look good with a massively blown out body part slider.  This is why I've gone to pains to modify a few tops for use with this mod, but there are a lot of female Townies out there and all of them are going to face this wardrobe problem.  The ideal solution is to re-do every mesh in the game with high poly counts and finely tuned weights, but until that happens I recommend using Deaderpool's MC Command Center.

With MCCC you can set CAS templates for ages and genders that limit the size of CAS parts.  If you set the range of the Breast Size slider to "-100 to 35" instead of "-100 to 100" Sims will have their body shapes restricted to something approximating the EA default, so you won't have to micromanage their figures and wardrobes as much.  You still have to change existing Sims depending on how you set it up, but MCCC makes adjusting other Sims easy both in CAS and through menus.

I will keep this in my downloads as a reminder to check up on it from time to time, but these Heavy Boobs causes all breasts to become torpedo- or worse, bananatits when undressing tops.

[Hermestris]

this looks amazing. worked great so far from testing. finally a mesh that looks good with big breasts!!!

I am trying to figure out to make it possible to push the breasts beyond the max size from this mod. is there any chance you could expand the slider range (could be optional)? Or i would do it myself but i'd need some pointers what to tune, as both me and chatgpt are at a loss here.

EDIT: I managed to do it myself. I edited the scale of the left and right breastbones in sims 4 studio.

If Heliotropic is okay with that i will share the modified file in case anyone needs.

在最近的 WW 更新（2025 年 7 月 4 日）之后，有没有其他人用这个 mod 遇到胸部形状奇怪的情况？下半部分突然变得尖锐且参差不齐；我会进一步排除故障，看看是不是因为其他 mod 的交互，而不是这个和 WW 的问题，但我更新后才注意到这个问题。

ME,TOO....HOW FIX IT? VERY SAD

This mod hasn't been updated in 5 years, nor has the author been around in over 2 years... Maybe if you credit the author it'll be fine until the they come back and tell you to take it down? I would love this. This mod itself doesn't seem to do much for me in the way of decent-looking breasts.

[Sir_CoolJerk]

The breasts definitely increase in size, but look nothing like the screenshots. The cleavage is barely able to be seen, and sometimes, the bottom of the breasts get jagged and are clearly separate from the body. Any help is appreciated. 

[RukiIsLewd]

So is there any better alternatives to this one?
