I created it with intention of generation small breasts with Flux. It has some issues, but it can generate different sizes of breasts pretty well.
How to use
On v1.0 and v2.0 positive strength means smaller breasts and negative bigger breasts (range is from -0.4 to 1.4)
On v3.0+ positive strength means bigger breasts and negative smaller breasts (v3.0 range is from -5 to 2.5 and v4.0 range is from -5 to 5)
No trigger words
Known issues
Changes lightness/darkness of the image
Sometimes it generates blurry images
Enjoy :)

v4.0 changelog:
- less lighting change
- can generate larger breasts
- deages subject when using negative strength
With current training process I don't think I could train a better LoRA. I have couple ideas how to improve it further, but will need to find a new training process. If you want to reduce the overall imapct on the image you might try not applying the LoRA on first couple steps.
The best one on Civitai!
I really like this lora. Nice job. I did have a thought though: would it be very difficult to create an age slider for women using your existing dataset? I find the aging part of the lora to be working exceptionally well, and would love for it to be a parameter that could be set independently of chest size. I am a little tired of having to beat the crap out of flux for it to generate a woman which looks to be even a day over 30
Since this LoRA was trained as textslider sadly not that easily (since I don't have any dataset). I could though try to train a age slider, but since fluxes architecture uses t5 it is quite hard to extract the exact feature and then the LoRA changes more of the image than is wanted. I will probably wait for image slider training to come out or if I have time I might hack something together (but lately I didn't have much spare time so not very optimistic about that)
Hello, can you give me some tips, or a flow model of yours to work with, I'm a beginner
How do you make such a concept would like to train a lora with a body feature too but i dont know with what kind of Pictures you did that. Did you trained the Lora with full body pictures or only breasts ?
V1 was trained with full body/half body images.
V2 was trained with images focused on breasts only.
V3 and V4 were trained as Leco text sliders, in V4 I just improved the prompt for training.

Perfect, simple, works!
Finding that this makes my characters skinny if they have smaller breasts.
Really messes with that pear shape body aesthetic.
How is this trained? How can positive and negative weights be used to control breast size? I want to learn how to do this.
Works great. Thanks.

anyone tried this with kontext?
Hi, its ramarkable lora i love it. Im using it for years now it worked very well, but lately it doesnt listen at all, any idea what could be the problem? Can other Lora be block yours?
