If booba good, then surely more booba more good, right?
NEW: Are four breasts a bit overkill for you? Would you prefer a bit less? Are you a huge fan of a certain scene in a 1990 Arnold Schwarzenegger flick set on Mars? Then check out Extra Breasts: Triple Trouble!
HOW TO USE: Current version is designed primarily for 4 breasts and does not use any trigger words. Select in Additional Networks or add to your prompt and go. Designed for use at 1.0 weight with NAI-based/anime models; for realistic models you may want to increase weight to 1.2 or 1.25.
Works great with topless/nude subjects, or subjects with clothing that fully covers the breasts (shirts, sweaters).
Works...not so great with skimpy clothing (e.g. bras, bikinis). My guess is that drawing a double bikini is something that is much harder for the A.I. to infer than just slightly changing the contours of a shirt or sweater. It still sometimes works at high (>=1.25) weights, though!
It's generally a good idea to add extra arms to your negative prompt...unless you're into that, of course.
ALPHA VERSION 0.2.4: Retrained exclusively on 4 breasts this time. This gives vastly more consistent results with both realistic and anime models, and interestingly enough will still sometimes output 6 or 8 at higher weights.
FUTURE PLANS: Unless I can find a way to more consistently control breast count using trigger words, future LORA releases will likely be designed for a specific count (e.g. one for 3 breasts, one for 4, one for 6, etc.).
Description
Retrained exclusively on 4 breasts. Should work more reliably with NAI-based models. Requires no trigger words; can still sometimes get 6+ breasts with high weight. Actually works with (relatively) small breasts now!

Been working so hard to get extra breasts to not appear on generated work, and now ppl are doing it on purpose. ;-)
Having this problem too, did you find out a solution? xD
@Jazzbacon You could always try using this LORA in the negative prompt, or with negative weight! Haven't tried it myself but it might help if a specific prompt is giving you extra boobs when you don't want them.
@chineseroom thanks!
Yeah, but booba 🤣
Oh, if you haven't worked the mutant titty issue in 6 months, then it tends to be caused by SD 1.4/1,5 getting messed up with anything other than 512x512px output. Start with that, then resize bigger gradually until you work out the optimal output res for the model you're using...
How did u train ur lora on a specific body part?
Same way I'd train it on anything else - gather a large enough set of sample pics, crop them down to focus on the desired subject matter, use the auto-tagger extension to generate captions, and then spend a long, long time fiddling with step count and learning rates until I get something that does more or less what I want. There wasn't anything particularly special about how I trained this one, but if you're having trouble with doing something similar I'd be glad to provide any pointers I can!
Interesting side effect is that having this at lower weights with certain checkpoints just makes longer/sagging breasts
This LORA has been my go-to consistently. It does have one notable flaw though, it's overbearingly trained on caucasian skin colors it seems, if the LORA is at moderate to full strength it overrides the skin color of any darker skinned characters.
Hmmm, I admit the training data is biased towards lighter-skinned characters and I didn't test much with more varied skin tones, but doing side-by-side comparisons with my most commonly used models (hassaku and AOM3), the effect on skin color by the LORA itself seems to usually be pretty minor. Not always, though, there are definitely cases where it it makes the breasts lighter than the rest of the skin or lightens skin tone overall. I'll try to get more diverse training data in my next attempt; in the meantime, I'd recommend using 'very dark skin' in your prompt - it's a separate booru tag and can much more reliably get dark-skinned characters with or without this LORA.
EDIT: After testing with a couple other models that can more reliably get a wide range of skin tones - yeah, this is definitely a problem. Thanks for pointing it out!
@chineseroom Thanks for the suggestion on the tag, that might hopefully help offset the effect. It isn't consistently stubborn, I've gotten characters like Chel to work with it fine, at least when clothed, but often when going for nudes that's where it applies the lighter skin to the nude areas even when the face remains darker toned.
Hexaboob version WHEN sir?
You can sometimes get 6 with high weights on the current version! That said, I've learned a lot about LORA training since the last release, so I'm hoping to be able to release an update with (fixed) breast count selection Soon (TM). Just haven't had a lot of chances to work on it lately...
way to turn a bug into a feature
