    This model has an apple shape bias.

    Main Strengths:

    • Creating a consistent body shape with a big belly and fat legs as the main focus.

    • It works well with LoRAs for SSBBW sizes and beyond. It increases size and adjust shape without frying the images.

    Weaknesses:

    Trigger words (it works even when using only these tags):

    BBW, Hyper Detailed Obese Body (optional, makes the subject considerably bigger)

    Quality Tags (improve the consistency of the generation of each part, I recommend to use only the tags corresponding to the parts that will be in focus): Fat Face, Voluptuous Breasts, Swollen Arms, Large Belly, Thick Lovehandles, Round Ass, Cankles

    Modifier Tags (add or considerably change some trait):

    Overstuffed Cheeks, Oversized Ass, Jiggle Move Effects, Fully Clothed

    Recommended negative prompt:

    worst quality, lowres, multiple navels, extra digits, extra legs, bad multiple views, bad perspective, bad face, bad hands, speech bubble, signature, patreon logo, sound effects, foreshortening, multiple views

    Recommended Weight: 0.5 - 1

    An interesting side effect of this lora I've noticed, if you add it to existing prompts that make very big sizes it adds even more size/enhances fat details further unlike any lora I've seen does.

    This observation interest me a lot. I suppose it is related the trigger word "Hyper Detailed Obese Body". The NLP from Illustrious understand the meaning of the sentence "hyper detailed". I probably would never have noticed it because I have the terrible habit of mostly using only my own LoRAs and hardly ever using captions. However, I am fully aware that some captions like "detailed" or "superflat" can highly increase the quality of the image.

    When you say adding to an existing prompt do you mean using without the trigger words? Did you try using the trigger words without the LoRA?

    Did you try making pretty big sizes with this LoRA? This was originally meant to be a LoRA for bigger sizes, but I considered the results over-the-top so I toned it down to BBW. Thus, it got a tendency to go bigger when provided of some margin to hallucinate, give it a large frame (16:9 should be enough) and, if you have time, test the tags "from above" and "Oversized Ass". Once you get the bigger sizes, tell how it compares to those made with pre-existing prompts.

    @blobgeek3102 The interesting part - With paired with no other loras? It behaves entirely as predicted and intended, even with the hyper detailed obese body trigger for the most part.

    But it almost acts like a size/fat detail "steroid" somehow when you get up to immobile and mega big sizes when used in conjunction with other large size or hyper loras.

    (IE: Everything embiggens and fatty details become more apparent) when paired with anything else that enhances sizes of parts or total weight of the subject. IE: The other SSBBW loras I've found, your other SSBBW lora included and the immobile inksplot lora.

    Though sometimes hyper detailed obese body does nudge it a bit larger, just using your lora at 0.4 strength seems to have this effect in general when paired with others regardless of triggers or key words.

    It adds more chin+cheek mass when paired with the two blobface ones as well!

    It just seems to have this "add on/boost" behavior when paired with others which is interesting, and it behaves as normal when not using your LORA or any lora at all as well using the same trigger words you included.

    It makes me almost curious if you used the same training parameters in this one but went all out on the size in the dataset if it would further amplify the effect or some sort of oddball edge case occured.

    Edit: Already done a lot of from above and bigger sizes and it does amp em up further as well to answer you too. To be more informative/exact it seems to boost up things more than either lora does on their own when you pair other fatty loras with it with these triggers, or at least it has for me.

    Fat face, chubby cheeks, double chin, morbidly obese, immobile, Hyper Detailed Obese Body, overstuffed cheeks,Swollen Arms, cankles,

    and if you use hyper butt and hyper hips then oversized ass seems to further add mass than the previous two alone.

    I tested it around a bit: https://civitai.com/posts/27945891

    The belly reaching the ground and the ass growing until it is as tall as the nape are traits very recognizable from the dataset which were successfully integrated int the alternative versions of this model.

    I will post a version of this made for bigger sizes soon. Then, you may see if you recognize similarities in the form produced by it.
