Anima
This version of the LoRA is build for Anima. It allows you to precisely guide where stretch marks should appear instead of relying on random generation.
Version 2:
Trigger Words:

You can freely mix and match these tags.
Recommended Settings:
LoRA Strength: 1.0
Version 1:
Trigger Words:
belly stretch marksbottom stretch markships stretch marksthighs stretch marks
You can freely mix and match these tags. For example, combine belly stretch marks and thighs stretch marks to get them on both areas simultaneously. Minor LoRA bleed is still possible.
Recommended Settings:
CFG Scale: 4.0 or slightly lower
Max LoRA Strength: 0.8 (suggested range: 0.5 - 0.8)
Important Note on Generation:
The model leans towards being slightly overtrained. At full strength, it can sometimes cause minor mutations or generate an excessive amount of stretch marks.
During development, testing lower epochs resolved the mutation issue, but the stretch marks lost their soft appearance and looked more like raw, fresh scars. To keep the correct, texture while avoiding mutations, simply lower the LoRA strength until you find the sweet spot.
SDXL Illustations
This model was trained purely on an anime/illustration dataset, and this is where it performs perfectly. However, it was also tested on realistic checkpoints. While the results on photorealistic models aren't always as flawless, it can still produce really good and convincing content if you play around with the weight.
Trigger Words:
belly_stretch_marksbottom_stretch_markships_stretch_marksthighs_stretch_marks
You can freely mix and match these tags. If you want a character with stretch marks on both their stomach and thighs, just combine belly_stretch_marks, thighs_stretch_marks in your prompt.

Description
Trained from scratch on a completely new, balanced dataset. This version is way more consistent and predictable than v1.
What changed:
White stretch marks: Changed the color and texture of the marks. Instead of red/scar-like lines, the model now generates natural white/light stretch marks that blend properly with the skin.
Better separation: Fixed the bleeding issue between body parts. You can use a single tag or mix multiple locations without random marks popping up elsewhere.
Replaced
bottomwithass: Removedbottom stretch marksand replaced it withass stretch marks. The word "bottom" in some cases was confusing the text encoder and causing unwanted close-ups on the lower half of the image.
Main trigger words (5 locations):
belly stretch marksbreasts stretch marksthighs stretch markships stretch marksass stretch marks
You can use them solo or combine them freely in a single prompt.
Bonus tag:
saggy belly- gives a soft, loose tummy effect (like a post-pregnancy belly or loose skin after rapid weight loss).
