BG3 Pregnancy Mod

---

Adds Pregnancy Mechanics to BG3

 

PregMod1.1.0 - BG3SX 1.0

PregMod1.2+ - BG3SX 2.0+

 

Features

• Current Features
  • Receive a curse after an eligible scene that, if not removed, will force a constitution saving throw to resist the pregnancy status
  • Progressive debuffs as time passes while pregnant (Long/Short rests)
  • Racial crossbreeding compatibility taken from This Document (any races not present are assumed to only breed with their own race, including modded races)
  • Passives that affect fertility
    • Infertile - cannot breed
    • Taboo - can crossbreed with anything (overrides infertile)
  • After a pregnancy ends, receive an appropriate offspring item (Baby/Egg)

 

Requirements

• No Hard Requirements - Most vanilla romance scenes can trigger pregnancy

 

Suggested Mods

• MCM - For customising the settings
• BG3SX - Pregnancy triggers from most BG3SX animations tagged as straight
• BG3SX Defeat - Defeat scenes pass time for pregnancies

 

Known Issues

• Dialog scenes target the current host player, this may cause issues in multiplayer - still haven't tested this in multiplayer
• While using BG3SX, there may be false positives when determining an animation's eligibility - this is less of an issue but now it's up to the animators' discretion, we've already noticed a few false positives but there's not much we can do on our side.

Do you think pregnancy bodies will be a thing? Nice mod!

[Luct1334]

Nice, hope to see more mods like this everywhere. Though I'm assuming it's for female characters only? At least at the moment?

Thank you! Bodymorphs would definitely make this mod feel more complete, but unfortunately they might be a bit too complicated for me with the BG3 modding tools currently available, for now I'd suggest getting a pregnancy body off of nexus and just equipping it when this mod progresses as a roleplay thing.

Any character can get pregnant, as long as they're in a female form when this mod checks for compatibility. For example, a male character can use disguise self to become female, get pregnant, then turn back and be pregnant in their original form. In version 1.0.1 there's now an MCM setting to prevent this mod from enforcing vaginas on pregnant characters. Characters cannot currently get pregnant from MxM or FxF animations, this is because BG3SX animations contain very little information about who would be receiving in those scenes.

That's cool, though I suppose I should have worded that differently. I'm assuming a male PC cannot impregnate a female NPC. Either way great work, even if it's not my particular cup of tea.

NPCs should be able to get pregnant too, in fact there should be no difference between NPC and PC pregnancy.

It's also worth mentioning that since wild shaping is currently disabled while pregnant, it's actually a valid gameplay strategy to impregnate any druid enemies before combat - Just something that came up while playtesting, we do plan on rebalancing stuff so druid PCs aren't completely nerfed by pregnancy in the future

Nice mod, it's almost compatible with mine, but I had to turn off Active rolls since it seems when the active roll is simultaneously applied to multiple player characters, the UI bugs out.

Rad, if clear enough space to redowload BG3 I'll be sure to give this a shot!

[MTester]

Pretty sure the Disguise Self spell is an illusion spell, not a physical transformation. Maybe make it so if you try to copulate with the spell when on the wrong gender it automatically get dispelled. The Alter Self and transformation spell is physical.

I get where you're coming from, but the intention of incorporating disguise self into this mod was to add a consequence for cheesing most of act 1 with a femme drow disguise. I'll add a toggle to MCM in the next update for those who think it ruins immersion.

How do you know someone is successfully impregnated? I see the creampie condition come and go, as well as the inseminated status given and lost in quick order. Do I have to rest a bunch to see any development?

From the screenshot, it looks like the characters weren't compatible, since the saving throw (and pregnant condition if the saving throw is failed) should show in the combat log. This could be happening if Minthara is already pregnant, the person you're pairing with Minthara is infertile (Vampires like Astarion) or from a race incompatible with Elves/Drow (there's a compatibility chart in the document I linked on the original post). I understand the chart may be a lot to memorise, so there's a toggle to turn it off in the MCM settings, or you can play as Dark Urge who just ignores it. If the characters you chose should be compatible, please let me know who you tried pairing with Minthara and what race they are so I can see if I can replicate the issue.

 

I will also note that the original pregnant condition is invisible apart from the combat log message, so it is possible to miss it

 

Edit: Condition is no longer invisible as of 1.1.0

I added the compatibility chart to the screenshots, so it's easier to access, also the next update fixes a number of bugs and will be releasing alongside our combat sex mod which is about 90% finished

[EnVeeToo]

The problem character was a vamp tav turned by astarion, so the undead tag might have been an issue. Works with the new version, though.

So yesterday I tried a durge impregnation and it worked, and I checked out the rest-progressed settings to see the pregnancy come to term in an in-game week (lol). I was now wondering, without the "gamefied" gestation, what is the original intended gestation progression?

Vampire Tav shouldn't be infertile as of the current version, so far only that's exclusive to Astarion, glad to hear your issue was fixed tho.

 

Without the gamified rate turned on, the pregnancies do not progress at all because apparently there was scrapped content around Minthara getting pregnant in the vanilla game (some of the dialog is even still accessible) and the impression it gave off was that the length of a playthrough wasn't anywhere near enough for a pregnancy to realistically progress to the point of it being noticable - this mod intends to readd that content in a way, which is why the default setting is for the pregnancies to not progress. The gamified rate just means that the duration is adjusted based on the game's mechanics -> 1 short rest = 1 month x the multiplier set in MCM, and long rests are worth 3 short rests

Love the mod, but a little disappointed in only getting a basket, at the end.

 

Any chance of getting a summonable child?  Your own interpretation, of Street Rats for Baldur's Gate 3 - mod.io?

 

I'll also add my vote, to any outward appearance change, during pregnancy. 

 

TY for your work!!  It's appreciated!

If you wish to use any of my pregnant bodies, or want to collab with a progression of bodies, I'm down.

 

- Sindae

[Hanapregs]

Oh it would be so sick to see the pregnant bodies with this mod!!!

[DT6666]

Cool, I like the concept behind it. Obviously things like body morphs and just getting a basket in the end are areas for further development but this is a good start. Regarding pregnant bodies, there's a mod author on nexus called sindae who's released a few body mods and I think in at least one the pregnant body is an outfit your character equips, so that could be a solution in the short term before body morphs are developed.

Is the Haarlep scene in BG3 as well as the post Haarlep scenes affected by the mod? 

And then there's this mod as well.  It would tie in very nicely IMHO.

The Haarlep scene is currently disabled because he can take either a male or female form during it and the game code isn't obvious about which is selected, but we do have a workaround coming in a future update. As for the Haarlep unleashed mod, any BG3SX scenes triggered by any mod should also trigger pregnancy if the actors are compatible, but we haven't tested every mod, so let us know if things don't behave as expected

[St8cy]

Update: Body appearance changes are currently our top priority, since it seems to be the thing most people are looking for. At the moment we're looking into if there's any way to scale the body's individual bones, so the functionality is compatible with every bodymorph and outfit mod, but we haven't had much luck so far, if anyone knows how to do this or any mods that do, please let us know as it would definitely speed things up. It's likely that this just isn't a possibility for BG3 with the current tools available, in which case we will look into custom bodymorphs, but we still have a few ideas left to try before then.

[wisdomtooth]

I have both installed and can verify that the Haarlep Unleashed mod does not trigger pregnancy.

[Celedhring]

Does unticking pregnancy checks result in automatic pregnancy? 

Now that Haarlep Unleashed has been updated to let players chose only heterosexual sex, could this mod be updated to allow impregnation as the result of post Haarlep decision "phantom use" of the target's body?   You can make it optional by allowing players to tick it on or off. 

Other than that, great mod.  It's part of my load order now.  And it's a excellent companion to Combat Rape and BGSX Defeat.
