    What is the offset vs 1.0? I haven't heard of an offset

    so, you basically just changed the useful weight range from -5/5 to -1/1, nothing else has been changed?

    SophoriumAug 23, 2023· 2 reactions

    Looks like previous one was inverted with neg 5 being galaxy size. This one is more intuitive at higher number being larger, and yeah looks like scale is adjusted

    @Defaud ah, that makes sense, too

    This is by far the best breast size Lora currently available. This one is extremely good at actually controlling the size without "poisoning" other aspects of the image.

    Below -0.6 you get some lolification and above 1.2 you start to get bigger hips and eventually weird effects but there is a LOT of adjustment in the usable range.

    Would you be willing to make a belly button slider that goes from an innie to an outie?

    This slider is great.
    If I could ask for 4 more sliders that would be:
    - tiny areola vs. huge areola
    - small nipples vs. long nipples
    - firm, upwards pointig breasts vs. hanging tits.
    - position of the nipples: up vs. down
    Hope that one day somebody can make these.

    Seconded on long nipples, like insanely long nipples, and firm breasts.

    @Hotcrossbuns I am working on a firm breasts checkpoint. Alrady got some success. Not a slider but the effect is the same. Have a look at my posts to see the WIP.

    @Hotcrossbuns Please have a look here.

    For tiny areolae im using "Large areolae LoRA" with negative weights. For firm breasts "perky breasts" keyword usually works fine.

    Very well done. I'm surprised this wasn't made a long time ago. I have a suggestion for improvement. The higher the slider goes, the more generally rotund the woman becomes. I know that larger breasts tend to be on fatter women, but I wish the slider exclusively affected breasts. There is a different lora I can use for weight. As this lora exists currently, if I set it to a high setting it also makes the woman chubby, which is not what I want.

    spicy_deluxeOct 16, 2023

    Combining with olaz's Tits on a stick lora seems to give you more room in the upper range before the rest of the woman starts to get bigger.

    The real test of this is seeing if it will cause unwanted toplessness, and from some testing, it appears to not, even if i pummel it with a request to do bottomless AND cleavage. I'm super interested in this "no data" thing. Also a slider for bottomless-ness would be interesting.

    I'll post the experiment results in the review section, since imgur isn't cooperating.

    spicy_deluxeNov 6, 2023

    Depending on what you're working with when you increase the values high enough it will start to do unwanted toplessness and at values higher than that starts to turn the legs into boobs but there's a remarkable span of adjustment before that starts to happen for most base images. What do you mean by bottomless-ness? Like a slider that makes skirts/shorts shorter and shorter or one that adjusts how much they're being pulled down?

    spunkymcgooNov 6, 2023

    @spicy_deluxe  the former, probably

    We definitely need an XL variant. Having very little luck controlling both clothed and unclothed breast size without it.

    It just generates the pictures itself based on your prompts.

    Great work. I also very much appreciate you linking the Ai-Toolkit git; hugely helpful for rescaling LoRa weights to target 1.0.

    I've been working with this lora for a little over a week now, all day long. Sadly when combined with a character lora, this changes the face, so much so that I was wondering why my character looked like 3 different very distinct people, seemingly at random. It also 'doubles up' the more zoomed in on the face you are. I'm sure if you aren't using a character lora then it works perfectly. This would be top tier if it didn't alter the appearance in any other way.

    KDMRKFeb 13, 2024

    agree, Every time i make with this, the result is different

    ExeterkerenkiOct 23, 2025

    I'm also having issues with the face contortions. Is there a fix?

    this lora with over 2~3 loras or some clothes make supermassive breast. lol

    I want a certain size, but I don't think I can use it after all.

    but still good lora

    Hi There,
    what exactly is the difference between the Slider 1.0 and the Offset? Is Offset just the newer version or does it function entirely differently? Not just because the weights are basically "inverted" between the two.

    Mr_BlackSheepApr 9, 2024

    I'd say as you just look the download rates, the second one is much better. I've got them both but only using the new version...

    I couldn't get it to work. The range is from -1.0 to 1.0, correct?

    anime2023Oct 10, 2024

    according to the photo, -1 smallest, -0.5 slightly bigger, 0 average, 0.5 looks like c cup and and 1.0 looks like d cup. example from given creator's prompt: <lora:breastsizeslideroffset:-1> then put the rest of your prompt.

    CrendagordFeb 25, 2025

    From what I've understood, AI generation is all about computing matrices and vectors. So there should be (theorically) no limit to models size. I've tried differnt weights for this model: https://civitai.com/images/60081316

    Intrestingly, negative values tend generate a younger woman, whereas positive generate a more mature one. Not only face, but clothing also

    anime2023Mar 1, 2025

    @Crendagord I learned something new. Didn't know there wasn't a limit on size. Awesome!

    I like the 1.0 more than the offset. It's weird using negative values for larger, but it feels easier to tune and control size with it. Every time I substitute the offset and go to 1/5th the value sizes it ends up not working for me. Great tool though.
