"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 :)"
