*** Version 2 Info ***
Version 2 includes some videos in the training data, which seems to help with prompts involving motion.
One thing I've noticed is that it really likes giving women long fingernails; I must have missed it in the training data and failed to tag it out. But I've just been putting "long fingernails" in the negative prompt and that seems to fix the issue pretty well.
*** Version 1 Info ***
A Lora for Wan 2.1 to help out with bigger natural breasts.
It's trained on the 14B model.
It works for Image to Video and Text to Video.
For I2V I'm using wan2.1-i2v-14b-480p-Q5_K_S.gguf and for T2V I'm using wan2.1-t2v-14b-Q5_K_S.gguf; it works on these, don't know how other models will perform.
The sample images were at a strength of around 0.85 to 1.00.
There aren't any specific keywords, check out the prompts on the sample images for what I use.
Enjoy!

God bless you
Fantastic!
Would love to see you make a vaginal cowgirl and reverse cowgirl lora one day!
When I do an i2v workflow and use this lora on an image of a woman with smaller breasts and prompt that she has large breasts, it doesn't seem to work. She looks almost exactly the same. However if you prompt that the woman's breasts grow, then she starts at her original size and gets bigger. Anyone noticed this? It's kind of a neat effect but sometimes I want a video that starts out with the girl looking more busty than the original image and that isn't working for me.
It's going to always start at the provided image. What youwant to do is edit the original image in inpainting or img2img and then start with that
Perfect
Would it be possible to have a version for big fake breasts as well?
Sorry, that's not something I'm into and I'm just focusing on stuff that interests me at the moment. I'm sure it won't be long until someone does create one though!
Any chance of doing a version of this where clothes can stay on? That is large breast and cleavage in a shirt, bikini,or dress?
Probably at some point, yeah
How do you guys keep the faces of the characters in the generated videos consistent, mine always have faces that tend to turn into another lookalike face
I2V or T2V? I have noticed when doing I2V with or without Loras, it does have a tendency to often lose the details of the original face. I don't know how to avoid this. When doing T2V the face generally seems to remain consistent across the video.
what strength are you using? Turn the strength down, I've found some can even work fine down at .5 or .6 but most work find at 0.7 that I've tested. That won't completely fix the problem, but makes it a lot better
This generally works great but it seems like when I use it with an I2V workflow the video always ends up beginning with a number of frames of blurry white video, then it sharpens up and runs normally. Anyone else had this? Is there a solution? I am mostly using it with I2V FP8 models in 480 or 720. This lora always seems to do this, but I tried your "cleavage" lora with the same workflow and a very similar prompt, and it doesn't do this. I haven't seen this with anyone else's lora either. Seems like it's just this one.
Yeah I have noticed this too and it tends to happen with Loras that I've trained on still images rather than videos. It may be that I trained this to 50 epochs and the cleavage one was only to 40, so it's having more of an effect? I'm not really aware of a solution unfortunately; I may do another version at some point.
same problem
It's a shame no one has come up with a lora for how big boobs behave under water. Then we could truly make underwater scenes.
humanity is ashamed
Maybe try the Breast helper LoRA, paired with the Breast Physics LoRA, and use a prompt like "Her breasts move naturally in slow motion" or something like that.
@PersonOfInterest Thank you for your answer but that will not work, Huge naked breasts behave totally differently under water than they do when walking. The bigger they are the more they react to every movement. To begin with they float more than any other part of the body. When a woman swims with big breasts and she has lets say at least a double D cup breast, as she swims the resistance of the breast with the water causes the breast to move downward on the body while it forms into like a cup shape do to the water pushing and they do the total opposite on the forward stroke. The same if she jumps up and down because of the water and the fact that basically the breast when stationary is like it is a separate entity to the body. Someone with breasts the size of Abbi Secraa has a more prominent reaction to being under water. A good way to look at how big breasts act under water is sort of like a jellyfish. Unfortunately footage of breasts larger than a double D cup pretty much don't exist. There are a couple of videos of Abbi Secraa in the pool but you only get glimpses of her breasts from above. The one thing about those videos is it gives you an idea of how breasts that big look when barely moving because of the fact they are floating they tend to form almost a torpedo shape that waves back and forth when barely moving and the slightest movement changes the shape or position. Do a google search for underwater big boobs and there are a few videos of double D cup breasts swimming, playing, during sex, and at rest in the water. You will see what I mean. I wish I could train Lora files for higher than sdxl but there has to be someone out there that can take what is needed from those videos and train for Flux or Wan 2.1.
@jtdragonflash964 Bro, im 41 years old. I know what under water boobs look like. lmao. I was just throwing out a suggestion to see if it would simulate a similar effect, thats all. 👌
@jtdragonflash964 Like, for instance if you pairs "large natural breasts", "Breast physics", and "Windy" LoRAs with a prompt specifying "underwater", you could possibly get similar effect...like, with using "windy" for skydiving, just add water. Again, just a thought.
@PersonOfInterest I wasn't implying that you didn't know what they look like, I was giving this description in case someone else read this comment along with where to look for files to train with.
@PersonOfInterest I'll give your suggestion of using the wind combination a try. again, I wasn't intending on making you look like you don't know anything. Just looking to find someone to make it a single lora file so we don't have to try combining too much. I would rather be able to have one file so other combinations can be used to accent the result. Besides that, It's hard to find everything needed sometimes because certain nodes don't want to work no matter how I try or look for alternative places to find working versions of that node. So the same goes with some lora files conflicting rather than working together.
I ran a few different combinations, myself, based on my own suggestion. The results were pretty good imo, but i definitely get what ur saying about having a single LoRA instead of having to piece one together. im about to post the ones i did, which will probably be done by the time you read this if u wanna click on my profile to see the results i got.
@jtdragonflash964 They are posted, now, if u wanna see the results i got.
That worked like a charm, I just finally got to see your underwater tits vids and they look realistic. Did you post the lora for this?
@PersonOfInterest I saw your results and they are wonderful, did you create the lora and post it? I would love to be able to test it on my machine to see what i can get it to do.
It wasnt a special LoRA. I did exactly what u said wouldnt work. lol
