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

[Xathras]

Just to confirm, is this new version (2025.04) backwards compatible with the last market version (2024.08)? I noticed it kept my saves from the older version and hasn't given me the "you are using saves from an older version" warning when I load them as it did before.

No, old saves are not compatible with new game versions (typically). Changes to python files technically won't break your save, but you won't experience any of the changes until a new save file is created.

Additionally, any RenPy variables that are modified - typically with a name change - breaks old saves files.

It would be nice to have a way to increase fertility by a lot without reducing breast size, sometimes I like my women with small tiddies

Bump !

Not really following what you want.
You have a serum that has 70% fertility and increase breast size from Nora.

Now if you meant you don't want them to increase then use the breast reducing serum along side the serum from Nora.
Just know that when they become pregnant breast will grow also just by being pregnant.

I also like small titties and use the breast reducing serum on all women all the time.

Hey guys.
My game gets stuck whenever I try a threesome with the mom and the sis. One of them asks to join, one gets in position, and they just look at me ) clicking or skipping doesn't change anything, i can only load an earlier save.

Sorry If I upset anyone, but I'm having some problems with the game, when I tried to save the game, it crashes, if I click desgin drug game crashes, someone calls me it crashes, did I do something wrong. Sorry no mods are installed. Oh and also right clicking anywhere and it crashes.

Obvious question is obvious, but... --snip--

Sweet, more AI mods. Small addition, to get stable diffusion to work with AMD you also have to add

--use-directml

Think any from the 6000 series and up should work.

sometimes i go back to the original thread and wonder "what ever happened to vren?" and what he would think of how far this mod has expanded his original game

Sounds like you got a bad download.

Re-download the game and unpack it again and see what happens.
Also you may need to update your unpacking software.

No changes to the parameters needed to run the game on Android correct?

Thanks, but I downloaded an older version that worked. For some reason new version wouldnt work, but you could be right was probably bad download.

Obvious question is obvious, but... You DID install stable diffusion locally, right? The mod itself requires a stable diffusion install, and isn't as easy as just drag & dropping the mod.

Let's assume that you're starting from complete scratch, since I'm sure some others out there are trying to get the mod running from nothing as well, and it's easier to just start here. It's strongly, strongly recommended that you don't do this on cards with less than 6gb vram, or on older 20x cards (if you're doing this on a 10x ti card, it's possible but jfc what are you doing), and assumes you're using an nvidia card.

1. Install forge (or reForge if you know what you're doing)
   You must be registered to see the links
   - I'd suggest doing the advanced install steps (downloading python 3.10, git, then doing a git clone of the
   You must be registered to see the links
   )
2. Download a model, I've listed two here, but the current genning standard is using an illustrious based model, such as
   You must be registered to see the links
3. Place the .safetensors model in your webui\models\Stable-diffusion\ folder
4. Locate your webui-user.bat file inside of your webui folder, !!!MAKE A COPY OF IT!!!, then (optionally rename, and) edit that copy with a text editor. Locate

   set COMMANDLINE_ARGS=

   and add the following to it after the ='s sign

   --port=7860 --api --cors-allow-origins *

   It is important that you use this copy to launch the webui when running the game. You want to leave the default webui-user.bat alone, and use that one when using stable diffusion normally when not playing the game. If you don't do this, and attempt to install extensions in to stable diffusion, you will have a very bad time.
5. Run copied/renamed webui-user.bat from the above step and wait for it to open forge in your browser
6. While waiting on the webui to open, download the mod and extract it in to the mods folder located inside of the game folder where your lab rats 2 exe is located. DO NOT LAUNCH THE GAME YET.
7. When the webui finally opens, it is safe to launch the game
8. Once loaded in to the game, click the GenAI Config button at the bottom of your UI
9. Scroll down, click 'Model' and select the model you downloaded/want to use (I'll assume you listened and used an illustrious based model, such as noobai, or the other two I listed)
10. Click 'Sampler' and select Euler or Euler A
11. Set Steps to 25
12. Set CFG scale to 5.0
13. Set your resolution to 1024x1024 or 896x1152
14. Set 'Auto Generate' to On to automatically generate images, or Off if you want to manually generate them. For simplicity's sake, set it to on and go talk to a girl. With any luck, you've installed everything correctly and it'll tell you when it's generating an image. All that's left to do is wait. Time taken varies based on hardware..

Quick question: where is the auto generate option? I can right click on Generate to choose generate forever. Ah, you mean auto generate in the game itself.

Thank you for this guide, here was my process in case it helps someone in windows. I had some trouble.

If you ever find the command window in dos doesn't work unless you press enter on it, it's because of a new windows feature. If you click on the window it thinks you want to enter input. You can go to the cmd.exe window properties, uncheck quiet edit.

I had an error with python because I had a different version already installed. This script requires 3.10.6. What I did is manually install 3.10.6, then delete the webui/venv directory. Rerun the webui-user.bat and it will continue installing torch

Continuing now, will update if I have more trouble.

You must do something like research or produce serums and so on.
Go to your bedroom and there is an option that will move the time forward and you should be able to tell what that is.

might be missing one or more tutorial missions by visiting each place in your company etc.

did all, try again and again

That's what you get for cheating, there is no way in hell you get serums up and running on day 0.
Hell you can't do it for at least 2-3 days and that rushing things.

Start over and skip the tutorial if your going to cheat like this.

Either you got a bad download or you skipped over part of the tutorial.
Each time you research take 1 time, producing serums every time you hit the button uses 1 time and so on.

I mean, the mod comes with cheats out of the box. But that's not the issue he's having. I am 99.9% certain that he saved and reloaded BEFORE talking to Stephanie at the bar on day 0, and it's thanks to serum_mod_core.rpy. This is an easily replicable bug, all you do is save AT ALL during the tutorial, before meeting Stephanie at the bar, and then simply reload that save. You're going to get hit with errors saying that the serum_mod_list isn't defined. You can ignore the warning, but if you do, it will break the game and you will be unable to advance time at all regardless of what you do. If you choose to simply roll back/scroll up to return to the last bit of game dialogue prior to the save & error, it will correct itself and the error will go away.
