Breast Expansion for Minimax H3
A companion to my other Breast Expansion LoRAs for Wan and LTX, this model works wonders with Minimax H3. H3 already has the ability to do some transformation scenes, so this model just gives that a little boost.
Important: As always with my models, this LoRA does not represent any real person in any way. If this model produces a video with any resemblance at all to a real person, that is purely an accident of AI random generation.
The model works for all the H3 workflow variants I've tried: text-to-video, image-to-video, and reference-to-video. Examples of all three are included in the sample set above.
Recommended settings:
For all rendering types: 0.7 strength
For best motion and the nicest overall look: combine with my H3 Busty Women LoRA and set both models to about 0.6 or 0.5 strength. In Wan and LTX, this setup would result in a very busty woman at the start, leaving her nowhere to grow during the scene, but H3 does a much better job of understanding the prompt so all you need to do is describe the woman's starting state and you'll be fine. I did not include any sample videos using this combination in order to keep the sample videos clean from other LoRAs, but I'll post some examples soon.
Downsides: This model was trained on silent video clips from other engines, so at full strength (1.0) the model has a tendency to leave the women's faces still while a voiceover voice is heard. Reducing the strength to 0.7 still gives you a great visual effect but allows H3 to add mouth movements to fit the dialogue. Just to be safe, I also include a phrase in the prompt like "Her lips visibly move in sync with the dialogue."
Also, H3 seems to really like to show off that it knows how to render nipples and will attempt to do so in unlikely situations. This is sometimes true even without any LoRAs added. I try to reduce this effect by describing shirts with "thick fabric" and so on.
I hope you all enjoy making scenes with this model and I can't wait to see what you come up with.

GOAT this looks great, thank you!!
Thanks, and thanks very much for the tip!
Thank you!
Is there a way to remove the nipples through clothing? It is like the model always want to apply nipples in anyway possible, hard nipples showing through clothes, visible through transparent clothes or just completely showing.
I struggle with that too, and I'm not sure if it's a training issue or just a minimax thing since I see it even when I lower the strength to very low values. You can prompt for thick clothing and that usually helps, and adding the busty women lora at 0.5 or 0.6 can also help with it. I haven't had any luck with negative prompting in h3, even though that's supposed to work. You can also try more steps and see if that makes any difference. I'm usually in a hurry and haven't given lots of steps a try yet.
@darkroast175696 Thank you - I will try that. Before your loras I also tried to do BE - Both with ref2v and flf2v and both have the tendency to generate the nipples regardless. I will have to test further, but perhaps it is the wording "breasts" that biases it towards naked, whereas bust, chest etc. perhaps introduces less nudity?
@AItinkere It's a good thought because I've seen that kind of thing in other models, though they tend to go for more "full bare breasts sticking out through clothing" kinds of issues so this is a step in the right direction? Anyway, you could try changing the wording and let me know if it makes a difference.
That was fast! And it works incredibly well - thank you!
Awesome! I can't wait to see what you come up with.
Looks Pretty Promising
interesting. I was able to do breast expansion on anime without the lora. I didnt try irl though
