Did you ever wish NPC Sims had more unique body parts? Instead of everyone having the same default WW body parts, you could download different meshes and have them distributed across the world. With the Body Diversity Mod, this is no longer just a dream!

 

This is a WickedWhims-dependent script mod that randomizes body parts (genitals, breasts, chest, tongue, etc.) across every eligible Sim in a save, with rarity-weighted selection, matching hard and soft penises, occult-aware part pools, and Khlas trait integration for size and sexual role.

 

What would you think of a version you don't have to set up at all? 

 

What it Does

• Scans all eligible Sims (teens to elders) and assigns each one their own independently-rolled set of body parts, sourced from a fully customizable external file.
• Automatically matches hard and soft penises.
• Applies occult-specific part variants.
• Marks every processed Sim with a hidden trait so re-running the randomize command automatically skips already-processed Sims.

 

Khlas Traits integration

• Applies the Big Cock or Small Cock traits according to the size of the penis each Sim receives.
• Applies sex role traits (Top/Bottom/Versatile) to all male Sims based on customizable distribution rules.
• Now the "ask about cock size" and "ask about sex roles" interactions are more meaningfull. 

 

What it Doesn't Do

• Block you from editing Wicked traits and body parts manually.
• Check for new Sims automatically. You'll need to type in the randomization command every once in a while to apply parts to Sims that have been generated or aged up since the last randomization. As a member of the potato PC club, I didn't want to give you something constantly eating up your RAM just to check for new Sims. It's pretty easy to just type the command, and you won't even need to do it that often.
• Change penis size through WW's penis size manipulation. If you use the attraction window to set your Sim to be attracted to big or small penises, it will have no effect. However, if you use the size preference systems provided by Khlas, those will work correctly.
• Apply textures and overlays, including pubic hair. This is a known annoyance because some penis meshes conflict with WW's pubic hair and make the penis look gross. I personally just turn pubic hair off.
• Apply matching condom overlays for NPCs. I tried to get this to work but ultimately decided it wasn't worth the effort. If an NPC has a non-default penis, there will be no visual condom on the penis, unless they have the condom packs provided specifically for that mesh in their inventory.

 

Requirements

• Whicked Whims LINK
• Khlas Males interactions LINK
• Body part meshes compatible with Wicked Whims

 

Instalation

(This is a new mod that has not yet been tested on many different computers! I'll probably be updating it constantly as people point out issues. If you encouter problems, please check if you have the most current version)

• Extract all files from BodyDiversityMod.zip.
• Drop the folder called BDM directly into your Mods folder. Do not place it inside other folders and do not rename it. The final path should be: Documents/Electronic Arts/The Sims 4/Mods/BDM
• The .txt file is just a reminder of how to install the mod.
• [SpcyYogrt]PartReviewer.html is used to set up the mod 
• The file called Tips and Tricks for Setup is a step-by-step guide of how I personally set it up. I highly recommend reading it before setting things up for the first time. It can look confusing at first, but once you understand it, it's quite simple.

 

How to Use

It is very important that you read this section carefully. How well this mod performs depends heavily on how you set it up.

 

1. Install the mod and all requirements. Don't forget to install all body part files you plan to use. If you install new ones later, you may need to set the mod up again.

2. Open the game and load any save.

3. Open [SpcyYogrt]PartReviewer.html (included in BodyDiversityMod.zip). It's an HTML file, so it will open in your browser.

4. Click Load all installed parts.

5. Set up your parts using the Tips and Tricks file as a guide. You'll notice that most parts don't need to be configured that much.

6. Click Export Config. This will download a file called body_parts_config.json. Drop it into your BDM folder at Documents/Electronic Arts/The Sims 4/Mods/BDM.

7. If your game is still open, close it and reopen it.

8. Load your save. From here, open the cheat console (Ctrl+Shift+C) and use any of the following commands:

 

• bdm.randomize_all → The most important command. It randomizes the body parts of all eligible sims (that includes sims in your current household, so if you want to choose those manually, I recommend you do that after using this command)

 

• bdm.randomize [First Name] [Last Name] → Randomizes only that specific sim.

 

• bdm.force_randomize_all → Re randomizes every sim, even if they have already been randomized before.

 

• bdm.force_randomize [First Name] [Last Name] → Re randomizes that sim, even if they have already been randomized before.

 

You'll have to periodically use the "bdm.randomize_all" command again, as the game will create new sims and the mod is not constantly checking when that happens. What I do is I run the command again every time I look at a sim and notice "hey! I don't think I've seen you before!". No, this will not re-roll sims that have already been randomized before. So if you know a sim that has a big dick from Noir, that wont change once you use the randomization command again. 

 

Know Issues

 

Parts not showing up in the Reviewer

Try opening the game and using the WW body part selector to apply the part you're looking for. If you can't find it in the selector, that part is either not compatible with WW or is missing a tuning file. If the part does appear in the selector, close the game and try loading the Reviewer again.

omg you are a HERO. Why did we never get this in wicked whims I still dont understand. is there gonna be a planned update to match pubic hairs with penises? cause now most are broken cause they are incompatible with the default pubic hair of WW. I also have the problem that when I force randomize the sims parts 90% of the time they will get no penis assgned to them (or maybe they get assigned to default?) while they will get assigned a tongue and a body. Do you know what might be causing this?

if any sims in the save already have big or small dick related traits, will the mod recognize that when randomizing?

that's a good question. No, I don't think so. It'll probably replace them with a new randomized one. But it's a good thing to add, I'll think about adding that.

You mean like force randomizing after you had already randomized them or the usual bdm.randomize_all command? In the reviewer you can set the default WW penis to be an option. If the extra penises you have are extreme sizes they might have a smaller likelihood of showing up. If you set the default WW penis to be small or everage, it will have a pretty big chance of appearing. You can try setting up the rarity of your other penises to be higher in the reviewer.

Having the default penis doens't necessarily mean penises are not being applied, specially since you sometimes see other penises. if you don't like the default WW penis, you can skip it in the reviewer.

Now for your other questions. Yes, I plan to some day make an auxilairy mod for applying overlays, but it might take a little while. I want to make it so it can apply not only pubic hair but also penis textures. Automatically mathing the color of the swatch to the overlay will be a pretty complicated task.

For now what I'm trying to do is creating some pre made settings file for people that don't wanna deal with the reviewer.

I follow all the instructions, but clickink in export config doesn't work for me. 😔 No file is downloaded

Can somebody help? 

Please and thanks

yes i use the force randomizeall so even the already randomized people get re randomized (that means the upper body will randimize so I know it works). the thing is most of the times they get assigned an errect default penis but this time when I open the WW body part selector, the default body part is not selected. In fact no penis is selected they just have the default penis show in game. so before I use the randomizer the default penis is selected,  if they get assigned another penis (the minority of the times) that penis will be selected in the list, but 80% of the time they will keep the default penis and if you open the list NO penis will be selected. My plan is to change the probability of the sizes appearing to exactly the same for all of them. Also as far as pubic hair is concerned I have completely disabled them in the WW options cause they mess with the penis 90% of the time.

ok got it. The "no penis" you're seeing is probably the native body part. I'll make a new version of the reviewer that removes those parts as options, but for now what you can do when setting up is going to "all parts", searching for native, then skip all of them except the male chest ones. It's also odd that a single part is appearing so often... Could you send me your config file so I can take a look?

Hi! Are you using the most current file available? There was a bug in the reviewer but I think it should be fixed now. If you're using the latest version and still having the issue, please let me know.

[Dwjliel]

Exceedingly cool.

 

For most users, I think you should automatically (somethinglike) set EVERY part to Rare, except Default to common, and say a 70/30 common/rare ratio. That way users could have a grab-and-go version and see the mods (great) effects.

 

I am a user who loves and REALLY appreciates the configurability; thank you. But from creating n sharing mods myself, I know many just want a "click and go" solution. You can still offer the configurability for those of us who want to use it.

 

Just some thoughts, absolutely zero complaints. Great mod, thank you for sharing!

Thanks! I'd been thinking about this functinality for years. It was amazing to see it actually working. 
I was thinking the same about the setting up process, I think it might discourage many players. Right now I'm working on fixing some other small issues, then I'll make a "just place in your mods folder" version.

Since this is new, I wanted to try and test this as fully as possible and made sure that I had some body parts for every category, which meant finding non-default feet mods specifically for this (which is something I'd never done before so it was a new thing to try and find lol). I observed that nearly everything in the WW body selector in-game did list in the Body Diversity Reviewer, including the listings for succubus-compatible parts if I were to have Nisa's Wicked Perversions installed. However, it would appear that either there is no category currently coded to read for feet (as it is absent from the drop-down) or it is having trouble reading for the feet category and therefore is not populating the category in the drop-down. I do not know how your mod is coded, so I do not know if the drop-down categories are hard-coded or if they populate based on the contents of the imported cas_parts_keeper_data file.

 

For now, my first run of the mod seems to have performed well. I do see where I want to adjust a few things for my own tastes, move some of the items I marked as uncommon to rare as I will have a few too many sims with uncharacteristically pierced tongues, but otherwise it seems to have done a very fine job.

 

For future additions, I thought to give some ideas that could work with regards to specific traits from gender mods like Lumpinou's LGBTQIA+ / Gender & Orientation Overhaul mod. In the config presently, I had it skip over Simdulgence's SimpleBreasts for males and SimpleChests for Females as there is no functionality to have them assigned to specific sims where these bodies would be appropriate. Functionality could be added to have this be randomly assigned to sims that meet certain conditions, such as the sim's CAS gender in combination with having one of the specific gender traits (Female, Male, Nonbinary, Genderfluid, Agender) from Lumpinou's aforementioned mod, then that would be different. Until then, I'll have to keep assigning these manually as I encounter transgender sims in my game.

Regardless, I look forward to how this mod will progress and improve. It was worthy enough of breaking my 8-year, no-post lurk!

About the feet issue: for now there is no feet randomization at all. The mod was originally made for personal use, and I since I'm not particularly into feet, I didn't think of adding that feature. The reviewer filters out entries in the keeper that are not relevant to the mod, so feet options are not included. I'm not opposed to the idea of adding feet randomization, it's just wasn't a priority.
As for the gender and sexuality compliances, it would be a very nice thing to add. It would require to dig a little deeper in the sim info and an aditional setting in the reviewer for top/bottom/versatile likelyhoods based on sexuality. But I don't think I'd integrate the compatibility with lumpinou's mod. I don't want to create too many dependencies because it's bad for the people that want to keep their game light.
And thank you for leaving a comment. I really appreciate when people go through the trouble of describing their experience using the mod. I feel honored that you used your first comment with my mod.

[cha_cha_lola]

Oh I wasn't suggesting compatibility specifically with any one mod, I was using Lumpinou's as an example regarding implementation and highlighting one possible use-case.

 

In the case of Lumpinou's mod, all sims regardless of whether they are transgender, cisgender, or something in between are assigned a trait indicative of it. I was merely using that as an example in terms of how, should traits and in-game gender be utilized with your mod's system, a person could really fine-tune the config to specify, "these tops are for sims with this CAS gender and this trait." I could see it being made as simple or as complicated as the user desires, depending on how it is implemented. I am no modder and my grasp of code in any form is far, far from anything tangible, so anything I say is really just hopes and dreams, but I like to think I can imagine something that could be possible lol

 

For instance, I could such a system being used for other combinations. Take, for instance, folks who make use of non-human body parts for their sims. They could use a randomization mod such as this, and in order to make sure it only assigns the appropriate parts to appropriate sims, assign the non-human parts to sims that have specific traits. It could be the reverse of how sims are assigned the Khlas Big Cock/Small Cock trait depending on the size of cock they are randomized with; If they have a specific trait, they are given one of the body parts designated for that trait.

But again, I'm no modder or coder, so I speak in hypotheticals and throw out ideas that you are free to explore if you so desire. Happy modding!

(please excuse me if I use trans insensitive terminology, I'm using the words the game uses to describe these things. I'm not a biggot, I swear)

Your comment actually gave me a lot of ideas for gender specific randomization. How it works is that WW has genital specific hidden traits (literally Has Penis, Has Vagina and Has Both, if you have a mod that can see hidden traits like Lumpinou's, you can check that). These traits (I think) are just to control animation behaviour.

On top of that, the game has hidden traits for describing gender options. Here is an example of a cis female sim:
 trait_GenderFemale
  trait_GenderOptions_Frame_Feminine
  trait_GenderOptions_Lactate_Can
  trait_GenderOptions_Pregnancy_CanBeImpregnated
  trait_GenderOptions_Pregnancy_CanNotImpregnate
  trait_GenderOptions_Toilet_Sitting

What I'm trying to implement is a system where you first select the parts that are to be applied to any non cis sim (penises for female sims, vaginas for male sims, breast for male sims and masculine chests for female sims) then the mod applies parts based on the traits mentioned above (e.g. sims who can become pregnant get a vagina assigned to them, sims who can lactate get breasts etc.) That way if you have any other mod that changes the way the gender options traits are applied, BDM should still apply the matching anatomy. 

Would that system be ok?

(I'm also working on the feet randomization 😉)

I fully understand utilizing the terminology as limited by the mod. It makes understanding more simple that way, at any rate.

And certainly, the hidden traits such as those for both male and female sims are utilized for a multitude of mods and I daresay a large number of modders are familiar with them, whether by way of modding or through use of cheats, so tapping into those and making them available for the user would be a boon. It would definitely be good, I think, to make it optional, of course, since not everyone will make use of all aspects; Like you, yourself, do not make use feet customizations, for example, and I do not either outside of testing your mod, but there are those who do. Same would be applied for the traits.

If it came down to it, the traits maybe could be applied as "default" to the standard "cis" assignments that WW offers, and then there could be an option available to make non-default choices beyond that, though again I'm no modder so I wouldn't know how to implement that.

 

EDIT: I also would like to point out what Luluso mentioned earlier, it does not appear to be randomizing teens despite the mod description stating that it scans teen to elder. I attempted to have it force_randomize a teen when I noticed and the message it gave me in return was "SKIP (age)"

You're totally right, there are a bunch of mods that use those traist too. Pretty sure WW reads them when deciding what parts it will make available on the body selector. So I think using them might be great for integrating BDM to other mods.

About the teen issue. It was my mistake. I checked to see it in the code and it looked fine, so I thought Luluso was just using an outdated version. But it turns out I made a little mistake when preparing the mod for uploading 😅. I've updated it and this should be fixed now.

Hi, is it possible to integrate random to only 'unplayed households' and ignore played households?

[Kokichi Oma]

OMG its very cool thank you! If you made other version with automatic pick when sim spawn ill be very appreciative

That's a good idea! Maybe I'll add to the next version.
What you can do for now is run the normal randomization then hand pick the parts for played sims. Since all sims have already been marked as randomized, the hand assigned sims will keep the parts you chose. Hope this helps.
