Ren'Py Lab Rats 2 - Reformulate [v2025.04]

[slick97]

I was looking for a little help on how to get the "family" pregnant Sister Mother Aunt and Cousin , I have the breeding fetish for both Mother and sister working on the Aunt and Cousin they are at their own apparntment and im working on the sexual nanobots. But I am hitting them with BC Suppression Fertility Enhancement etc etc But nothing.

you dont need all that, either convince em to stop taking the pill (can be done many different ways), or use bc suppression and keep cumming in them...vaginal only, anal impregnations have very low chance of success

The method for determining when a girl becomes pregnant is both simple and complex. More succinctly, the game checks a few things:

1. Did you cum inside
   • Each instance of cumming inside runs the did_she_become_pregnant function
2. The effective fertility of the girl each time you cum inside her which is based on the following:
   • Game pregnancy preference (realistic = harder, Predictable = easier)
   • Days from ideal fertility (closer to the "peak day" = higher chance)
   • Ferility_percent - the base fertility score (max age = 78, highest fertility (@ 18) = 20%)
     • Note: Starbuck changed this awhile ago to add another multiplier to normalize values to between 3% - 6%
   • Fertility aura perk for MC (adds to fertility percent)(Small = +0.2; Medimum = +0.3; Large = +0.5; maxes at 25%)
3. The pregnancy chance which takes into account:
   • Effective_fertility = fertility_percent * ( 2 - (day_difference / 10) )
   • birthcontrol_efficiency = ## - bc_penalty (## depends on pregnancy preference; bc_penalty is determined by serums)

Every time you cum inside a girl - including during the same sexual encounter - the game rolls a number between 0 and 100 twice. The first check passes only if the effective fertility is higher than the random number selected. The second passes only if the birth control efficiency is lower than the random number selected.

tl;dr - You're dealing with low odds even in the best circumstances (see spoiler for some statistics)

You can see their fertility rate/change in the persons info screen at the top, just click the '?' on top of the screen when talking with that person to see their stats. now just like RL, the fertility rate fluctuates during a month, so it could be awhile before you hit 'peak fertile' period. Of course you need to get em to stop talking birth control before that.

What are you trying to name your serum? Trying to use any characters that are operators in python will result in an error. I don't know if this is that error but just getting that out there in case

Reinstall Joiplay and try again. If the error still persists you can try downgrading to a previous version of Ren'Py (others on the internet have better documentation on how to do this).

I tried reinstalling Joiplay and Ren'py and didn't work, I tried downgrading and didn't work either

Anyone else getting errors when loading a save from 2024.09 beta version? Normally i'd click ignore and go ahead on most Renpy games but this restart it to start of the game.

Edit: Checked on older version the save seems to be fine. The error screen is in spoilers.

Hi! and is there a way of debimbification, "legal"? the event with Stephanie, when she took this bimbo serum and then took the counter-serum - does this mean that such a debimbification can be developed, that is, bimbification is reversible? or is the event with Stephanie just a "thing in itself", a game convention, "god from the machine" I don't know what to call it.

Your "pregnancy preference" setting is set to "disabled" (included in the base game). If you change it in the options ("preferences") then the information should be displayed upon next save load.

For additional information, Starbuck also stated in this post that they're currently working on the save compatibility issue.
