What does this mod do?

As the title suggests, this is a pregnancy mod for skyrim. Currently the mod works as follows:

  • If you play as a female character, you will now have a menstrual cycle that passes through 4 phases: menstruation, the follicular phase, ovulation and the luteal phase.
  • This mod itself does not allow you to have sex, but when you have vaginal sex through any SexLab plugin, you will receive sperm which survives for some time.
  • You can attempt to wash out the sperm. This is not guaranteed to work, although the chance can be configured.
  • If sperm is present when you are ovulating, you might become pregnant.
  • If you get pregnant, you will pass through 3 trimesters. Each trimester has unique spell effects associated with it (most of which are negative, but some are positive).
  • The visuals (e.g. increased belly size) relies on the use of either body sliders or a skeleton that supports belly node scaling. Read more on this in the installation section.
  • At the end of pregnancy a child will spawn. The child doesn't do anything at this point though, there's no follower features or anything like that.
  • The duration of pretty much everything that has a duration, as well as some other stuff, is configurable in MCM (be wary though - the pregnancy duration settings are disabled when pregnant).
  • Many of the durations and chance rolls are modified by both the mother and father race. This is attempted to be as lore friendly as possible. The race modifiers can be disabled if desired.

What does this mod NOT do?

  • As mentionend, the child is kinda static after birth. There's no follower features or anything like that.
  • NPCs cannot become pregnant.

Installation

If updating from version 1.0 to 1.1

 

Only follow these steps if you have already installed version 1.0 and wish to upgrade.

  1. Make sure you are not pregnant and have no active spell effects from this mod. Save your game.
  2. Delete SkyrimProcreation.esp and all files in the "Data/Scripts" and "Data/Scripts/Source" that are named as "ProC....psc" or "ProC....pex".
  3. Create a new save again.
  4. Copy the files from the data directory in the "Procreation 1.1 rar" file to the Skyrim data folder. Make sure to activate the SexLabProcreation.esp in MCM or the Skyrim Launcher (or the load order ini file).

Required mods

  1. SKSE 1.6.15 or newer
  2. SkyUI 3.4 or newer (also works with SkyUI 4.0)
  3. SexLab Framework 1.01 or newer

Steps

  1. Backup your save file(s).
  2. Install the required mods (including their requirements).
  3. Copy the contents of the Data folder in the "Procreation v1.1a.rar" file into the Skyrim Data folder and enable the "SexLabProcreation.esp" in the Skyrim launcher or in NMM.

At this point the mod will work, but the belly size will not change when pregnant. This can be changed in two ways. They each have their advantages and disadvantages, and you should only choose one. Skeleton node scaling is the easiest, but it has no armors converted for it yet (as far as I know):

 

Set up belly size management with skeleton node scaling

  1. You need a compatible skeleton, such as XP32 Maximum Skeleton. Other skeletons might work, as long as they have a node named "NPC Belly" which simulates a pregnant belly when scaled (and two other nodes named "NPC L Breast" and "NPC R Breast", but these are more common).
  2. You need a compatible body mesh. Currently two compatible meshes exist as far as I know (as of June 1st 2013)
  3. ​b3lisario's UNPB BBP mesh, which can be found in the Esutrus Chaurus download section
  4. zecoron's CBBE TBBP mesh

Set up belly size management with weight scaling

  1. This is only necessary if you're not using the skeleton node scaling feature mentioned above.
  2. Install Realistic Body System or Unique Character or Custom Races. If you don't do this, all female NPCs will look pregnant.
  3. Install either CBBE or UNP and the appropriate bodyslider. Set up your character in such a way that you look "normal" when at minimum weight and "very pregnant" when at max weight.
  4. If you use Unique Character or Custom Races, copy the meshes created with the bodyslider into the appropriate folder. Check the individual mod pages to figure out where this is.
  5. In the in-game MCM menu, navigate to the Pregnancy section of SexLab Procreation and change the Visual Scale Type to Weight before you get pregnant.

Conflicts with other mods

Depending on whether you use the skeleton node scaling or the weight scaling, there might be some conflicts:

 

Skeleton node scaling

This mod overwrites the skeleton node scaling done by other mods, such as Estrus Chuarus or Race Menu. If you use Race Menu it is recommended that you don't use the Breast scale feature. If you use Estrus Chaurus, don't get pregnant with both mods simultaneously. Disable pregnancy with one mod when pregnant with the other.

 

Weight scaling

If you use the weight scaling option, this mod will conflict with any other mod that changes your weight.

 

Uninstall

I cannot entirely predict what will happen if you uninstall, though I recommend that you make sure you are not pregnant, and do not have any spell effects from this mod active. The mod contains the following files which should be removed:

 

Data\SexLabProcreation.esp

All the files that fit this description: Data\Scripts\Source\ProC... .psc

All the files that fit this description: Data\Scripts\ProC... .pex

 

Troubleshooting / FAQ

My belly size doesn't increase when pregnant.

Make sure the Visual Scale Type in the MCM menu under the Pregnancy page is not set to None. Make sure you have followed the steps in the installation section properly.

 

I want to use the weight gain feature to manage my belly size, and I gain weight during pregnancy, but my belly still doesn't look pregnant.

You did not setup the CBBE or UNP sliders properly. Open the sliders, set the minimum weight to the body type, size, etc. that you want when you are not pregnant. Then set maximum weight to the same settings, except with the changes you want your body to go through during pregnancy. This obviously means cranking the pregnancy slider up, but you might also want to increase the breast size or other sliders. Once you're finished setting up the sliders remember to click the "build" button. If you're using this mod, don't think of the weight sliders as representing "body fat". Think of them instead as representing "pregnancy progression".

 

I want to use the weight gain feature to manage my belly size, but I don't see any pregnancy sliders in the bodyslider I use.

If you're using CBBE you need Bodyslide CB++, and if you're using UNP you need Bodyslide UNP. They can be found here.

 

I'm not using CBBE or UNP.

Well, then you're kinda on your own.

 

If you want to use the weight scaling feature, you need the femalebody_0.nif mesh located in "Data\meshes\actors\character\character assets" to look non-pregnant, and the femalebody_1.nif in the same directory to look very pregnant. If you have the non-pregnant and pregnant meshes from somewhere else, that's totally fine. But using the CBBE or UNP sliders is easiest.

 

If you want to use the skeleton node scaling feature, you need to a mesh that supports scaling of the nodes "NPC L Breast", "NPC R Breast" and "NPC Belly" to simulate breast size and pregnant belly size. At this time, only b3lisario's UNPB BBP mesh found in the Esutrus Chaurus download section has this support.

 

I want to use the weight gain feature to manage my belly size, and I installed the pregnant meshes properly and they are working, but now all female NPCs look pregnant!

Yes. As far as I know there are three ways to solve this:

  1. Use Realistic Body System
  2. or Unique Character
  3. or Custom Races

Using Realistic Body System is the easiest as it replaces the meshes for all NPCs, however, Realistic Body System isn't always the smoothest experience. It doesn't always fit the clothing to the body types it creates, which can cause severe clipping issues. It also has a tendency to translate random parts of your game into german.

 

If you use Unique Character or Custom Races the pregnant meshes you create in the CBBE or UNP sliders should be copied to the appropriate location. This location can be found in the mod descriptions on their respective Nexus pages. After you've copied the pregnant meshes to the appropriate folder, NPCs will still look pregnant. You now need to change the standard meshes back to a non-pregnant version with the CBBE or UNP sliders. This should not overwrite the pregnant meshes you copied into either the Unique Character or Custom Races folders which you will be using.

 

I installed the mod but nothing is happening.

Try waiting a day or two and the menstruation phase should start. Also, you have to be female. NPC pregnancy is currently not supported.

 

The procreation quest objective disappears after the menstruation phase... is the mod still working?

In all likelihood it is still working fine. If the "Information Level" setting on the General page is set to LOW, then it is intended to disappear. If you are in doubt about whether the mod is working, try having vaginal sex. You should get a message. Alternatively, or if you don't get a message during vaginal sex, try setting the "Information Level" in the MCM menu to HIGH and wait a little more than the duration that your current phase is supposed to last (e.g. if your current phase is the follicular phase and it is set to last 4 days, wait at least 5 or 6 days). If you don't get any messages about anything, something is wrong. Try asking in the thread or sending me a PM with more specific information about what you did and what happened.

 

No "SexLab Procreation" menu shows up in MCM.

This only seems to happen with SkyUI 3.4. If you don't want to update to SkyUI 4.0 for some reason, save your game and reload. I'm not entirely sure what causes this. It might have something to do with load order but I don't know. Anyway, just save and reload and it should be fixed (or update SkyUI to version 4).

 

About NPC Pregnancies

I understand people want this feature, and I'd very much like it to be implemented. A lot of people are giving me ideas about how to implement it, which I appreciate, but it's not really the main issue. The issue is that implementing NPC pregnancies in a way that wouldn't totally kill performance would require either a complete rewrite of the mod or a separate mod. In either case, it would require a lot of work. I don't really have the time or desire to put in the kind of effort that would be needed to create this right now. Perhaps I will in the future.

If your going to do sliders could you do a separate mesh for the pregnant bodyshape, possibly a separate mesh for each race?

Link to comment

This works by changing the players weight, right? If so, Unique Character should isolate player body meshes as well. Armor meshes could be handled with standalone CB++ ones. A lot cleaner solution than Realistic Body System. That thing blew up on me badly.

 

I think I'll try a game profile later this week and test it out.

I see some great things about this mod and some things that are going to be very difficult (with any pregnancy mod). 

 

Easy: Pregnancy body

 

The pregnancy body is going to be an easy thing to work with because bodyslide makes the creation of the meshes very easy to do and the weight slider effect makes it so that your character can just progress the weight tool on them to show the pregnancy advancement.

 

Difficult: Weight Slider Effect

 

Because all different Player characters and NPC's can have very different body size starts (start of the body size before pregnancy) I see making the pregnancy body follow of the in-between body sizes that are not either at the very top or bottom of the weight slider set to be extremely difficult and space consuming (several gigs for all the necessary meshes) if not impossible. It would also require the meshes for the different armors to be set up as well to show the big belly (unless you don't mind a second trimester belly magically disappearing under the armor). To get all the meshes easily in the right spot, Stuffed_Bunny may need to be approached about adding an effect to the bodyslide tool that tells it to designate a created set of meshes as pregnancy meshes so they are not just automatically placed in the mesh folders for the conventional armor re-mesh. 

 

Awesome: Core Concept

 

This is one of those mods that this game really needed now that the framework has been set up and so it is very cool to see that someone has been working on it so major KUDOS to Trixy.

 

One suggestion (no idea if this can be done) it might be more efficient to come up with a way to combine the weight slider for characters with the belly progression of a pregnancy to avoid the need for several thousand meshes just to ensure that every weight point has a pregnancy belly progression set to go with it.

Very, very impressive.

 

I just hope we get a UNP pregnant body to go with it. And an actual BABY model for once, even if its just a static object. Over three games worth of pregnancy mods we haven't had one where its handled 'realistically'. Not your fault of course, just noting. For roleplayers it sadly makes the mods of dubious use without a pretend-timeskip to explain the pregnancy and having a ten year old. Even just a static wrapped-baby model would work fine, because it would be adequate for rough a year and a halfs roleplay, and few ever last that long.

Not 100% positive but something in this mod is causing this:

 

Sometimes when I un-equip an armor, my character's body goes flat (Boobs and butt disappear)

 

Turns out something is causing my character's weight to go from 1 ----> 0 (Figured it out through racemenu)

 

It just happens randomly....

 

Anyway i can stop this?

I'm sorry, but no. This mod will set your characters weight to 0 when you are not pregnant. You should configure your body to look how you want it in the CBBE or UNP sliders. Instead of thinking of it as "weight" think of it as "how pregnant is my character", if you are using this mod.

 

I know this is not optimal. Ideally the belly size would be managed through node scaling, but for now it will be managed with weight and bodysliders.

Apparently the newest xp32 skeleton has a pregnant belly node. If so, NetImmerse.SetNodeScale could be used to set the size of the belly. I havn't looked too much into this, but if it could be done by setting a node of the skeleton, I think this would be the best solution. And thanks for the Kudos :)

 

 

Very, very impressive.

I agree that this would be a better solution... but aside from a baby model it would require a pretty extensive mod system on top of the pregnancy mod itself. It may happen some day, but I'm not likely to do it.

Great work! Thankyou for taking the initiative to do this Trixxy!

 

Although I am aware it's still at a very new stage, wouldn't it be possible to modelise a baby as an object the character cradles and has to take care of for a period of time before the child actually spawns? It could provide a temporary solution to the static NPC while this is worked on :)

 

I think someone had mentioned this before in another thread and I'm surprised no one took any interest in the idea of a "baby stage".

Anyhow just food for thought.

I figured out the concept on this.... but It's impossible to use this with Tbbp meshes.... isn't it?

 

Currently using the bodyslide meshes with tbbp and testing this mod.

 

Btw, the queststage for the Menstrual phase isn't in my questlog anymore, maybe I'm in the Proliferative phase (dunno if 4 days went past), but now the log doesn't show any procreation quest.

Was this intented?

edit: phase3 quest popped up again.

@Trixy

 

First of all, thanks for releasing this mod, I can see that a lot of hard work went into the scripts.

 

 

I thought that I might add my 2 cents on some of the issues being brought up.

 

 

Weight slider based body is quite feasible, especially in my case, where I use the _0 body exclusively for my custom UNP character, so an extra _1 body doesn't really affect any other NPCs in game.

 

It is also fairly easy to draw up a model based on the default _0 body, whatever it may be (UNP/CBBE/AEDC/Custom/BBP/TBBP/etc), a process that literally takes ~15s in 3ds (open, displace verts, export), and also gives the end user much greater control over the final size/shape/proportion of the body.

On the other hand, using ninode to adjust the belly size is a much more foolproof method, as it requires no input from the end user, but it does suffer from quite a few issues.

 

For instance, all the body meshes UNP/CBBE/AEDC/etc will have to be re-rigged to include the new skeletal node, and all the outfits would also need to be re-rigged to make them compatible with nodal scaling (much like converting an armor piece into BBP/TBBP).

 

There's also the problem with extrapolation limit, such that systematic nodal expansion would never look as natural as hand-crafted meshes, and nowhere near as variable/customizable.

 

 

Furthermore, nodal scaling is enabled via SKSE/racemenu, and sometimes glitch out, producing rather irregular oddities, but that's a whole new can of worms...

 

 

 

Of course, I understand that both weight based and nodal based expansion would require clothing be converted to support the changes, and the amount of effort required is rather similar for both cases (weight map manipulation vs vert map manipulation).

 

However, the two methods are not cross-compatible, thus in order to minimize confusion, I would suggest that the modders come to a consensus and stick to one method, otherwise it would be rather problematic in terms of outfit support.

My custom lovergirl race can get pregnant and so can my normal vanilla character, yet when it comes to 2nd trimester no body change happens and so forth. I respect early stage of this mod and I appreciate the time and effort you have taken, at least we have beaten the Japanese modders for once. I for one hope you continue to work on this and improve, now just waiting for creature animation and skyrim will be perfected... all body sliders and links you supplied are all installed correctly so just might be my misfortune.

I'm sorry, but no. This mod will set your characters weight to 0 when you are not pregnant. You should configure your body to look how you want it in the CBBE or UNP sliders. Instead of thinking of it as "weight" think of it as "how pregnant is my character", if you are using this mod.

Okay thanks for clearing that up

 

made the appropriate changes in bodyslide  :D
