    Perfect Breasts XL V1

    This slider is designed for SDXL models like PonyXL, Illustrious, and other compatible bases. It’s perfect for enhancing or minimising breast size while leaving the rest of the body, including the hips, waist, and age, unaffected.

    Key Features:

    • Precision control: Works seamlessly in 0.10 increments for fine-tuned adjustments.

    • Tested extensively: Delivers consistent, natural results between -0.5 (smaller size) and +5 (larger size).

    • Targeted impact: Minimal effect other body areas, including hips, waist, or age, and has no effect on male characters.

    • Broad compatibility: Optimised for popular SDXL models like PonyXL, Illustrious, and more.

    • Effortless activation: No specific activation prompt required—simply adjust the slider for immediate results.

    Usage Tips:

    • Pair with tags that specifically reference breasts or chest size for enhanced effects.

    • Avoid overloading prompts with multiple LORAs or unrelated tags to maintain a natural, balanced look.

    Pro Tip: If certain details like clothing, shadows, or skin texture require extra attention, add supporting prompts to refine the outcome further. Negative prompts can also help maintain balance, particularly if over-emphasis on certain features occurs.

    Does your Lora work when breasts are under clothes? I'm generating a girl in a small top and am having trouble increasing breast size

    @kareslav It does, ensure you use "covered breasts" in positive and "breasts out" in negative. Also, check my Puffy Breasts slider, it does it bit better

    I am somewhat new to this. But I've put the Lora in the right folder and connected it correctly in the ComfyUI workflow. It is loaded with a model/clip lora loader. This load node allows you to adjust the strength of model and clip, but these adjustments do not seem to affect my resulting image. Strength 1 in both fields should give a strong effect, of course. But the real question is: How can this be a "breast slider" when there is no slider in it? How is the breast size supposed to be controlled using this lora? Please answer in detail, as seen from laylas comment others are in doubt also - and your fine work is wasted, if others can't use it, I think.

    I tested it, inserting lora:Breast Size Slider:0.1 and <lora:Breast Size Slider:0.1> and various other numbers in the prompt, with the strength of the lora set at 1.0 in the lora loader. That has NO effect. I'm using base model Pony Diffusion V6 XL.

    @mkaastrupchristiansen560 this is an issue with your setup and not with LoRA.

    @klaabu: That may well be. Would you kindly explain how your lora is supposed to be used then? In my setup, it is simply inserted as a lora loader (model and clip) after the checkpoint and before KSampler, which ought to be correct. Are you saying the lora cannot work with Pony Diffusion V6 XL? If so, which checkpoints does it work with?

    @mkaastrupchristiansen560 I don’t use pony v6. Try to use it on other pony or ILXL models :)
