    👇👀 Read me! 👇👀

    This is a unipolar slider for PonyXL. The purpose of this slider is to increase the subject's breast size in a controllable fashion with the LoRA input values. Higher LoRA input values result in larger breasts.

    What makes this slider special is that it is largely decoupled from age. Making a breast size slider is not hard, making a breast size slider that doesn't overly influence age is hard. This slider does the best that modern tools allow for decoupling age from breast size, and in my opinion it does a good job at that.

    Supported input values are 1 - 5, however going above 3 often yield excessively large breasts. Negative values are not supported for this slider, use at your own peril. Please be aware that whatever breast size you prompt (if any) will be the base that the slider works off of. For example, if you prompt huge breasts and then use a LoRA weight of 3, you're going to get absolutely massive honkers. For the same prompt, if you prompt flat chest instead and use a LoRA weight of 3, the breasts will be much smaller than if you used huge breasts. The LoRA slider works like an offset in this regard.

    No Activation prompt. Example prompt:

    score 9, score 8 up, score 7 up, (source anime), 1girl, (maid), cleavage, solo, sitting, legs together, thighhighs, cowboy shot, head tilt, (hand on breasts), areola slip, evil smile, open mouth, looking at viewer, blue eyes, blonde hair, long hair, (bedroom, on bed), detailed background, <lora:StS-Breast-Enlarger-Slider-PonyXL-v0.8:2.5>

    If you have issues using this LoRA, feel free to send me a message on CivitAI and I will help you out if I can. If you are running into use cases where this LoRA breaks down and/or freaks out, please let me know so I can fix it for future version releases.

    Bro, i thank you, most breast expansion/size changing lora's are either too wonky or too overcooked, I'll definitely try this out, in place of my normal expansion/size changing lora.

    @pokezilla39966 I put a lot of work disentangling this slider, so if you run into it being wonky or overcooked please let me know so I can put out an updated version to address those issues :)

    @Shed_The_Skin sure thing, will let you know how it goes :D

    @Shed_The_Skin one thing, the file that is there to download this lora, comes to a name of 0.8 version, could you make sure the linked file is the right version?

    @pokezilla39966 That is the correct version. I gave the initial release a version number of 0.8 in case there were problems with it. I didn't have quite as much time as I wanted to in order to test for edge cases.

    Edit: I just saw that I labeled it on CivitAI as v1.0 . Fixed that now.

    @Shed_The_Skin ah, ok, thanks for checking, sorry for the confusion, i was just confused as you had labeled the page as 1.0, but the file was 0.8, but thanks for rectifying this :D

    Great lora! Do you think you would be able to do a weight gain slider next?

    @ayylmayo97671 Thank you for the suggestion, I will look into it.

    @Shed_The_Skin Would be also great to have a slider for zoom in/zoom out the character in photo.

    Awesome Lora that works great.

    Can I suggest you create a Hip Width slider?

    being decoupled from age is a huge reason why this slider is better than most. there have been times I wanted to see what this normally big booba waifu looks like with normal sized or small breasts. and every time it would turn them into kids or something I don't want. this Lora doesn't have that problem for the most part, so good job! I cant imagine how hard it was to separate the two

    could you make a "breast diameter slider"? or "breast width slider"? no one has made that yet.

    @OrangeJuiceAlien How is that functionally different than a Breast Size slider?

    OrangeJuiceAlienJan 22, 2025· 2 reactions

    @Shed_The_Skin "breast size" is the whole size in all directions, while "breast diameter" or "breast width" is the left/right/up/down dimensions independent of the "depth" of the breasts. without such a slider, its very hard or impossible to create breasts with a small width and high depth (clear separation in the middle the two breasts) or breasts with a large width and low depth (almost no separation in the middle between them). I would like to be able to control that.

    Works great, especially for newbies.

    Bad.

    Makes everything bigger. Can't do thin woman with big breasts. Only fat hogs or ultra thick woman. (Used CFG: 1-3 as you said) And it literally changes the age too.

    @setmefree01969 Thanks for your feedback. Would you be willing to share some of your generated images (with metadata) so I can look into the issues you reported? On CivitAI, I don't see any images from you.

    @Shed_The_Skin  I already deleted them, sorry. I am new, so I didn't upload pictures yet (and probably never will). But I can tell you what I used/did. On ComfyUI with "Pony Diffusion V6 XL", 25 steps, euler, simple, CFG: 7-12 (tested around) and that's it. I even added tags for slim body or thin body or slim legs and so on, but I always got curvy women or almost fat women. The only thing I did not do, because it "Pony Diffusion V6 XL" won't work otherwise, is to set Clip Skip to 1. I have to leave it on 2, or it will only generate noise. But this never was a problem so far with my other 20 LoRA's.

    EDIT: But your Age slider rocks!
