Breast Expansion

Wan 2.2-5B:

Trigger words: Br34st 3xpan510n

This new version of my breast expansion lora has been trained for Wan Video 2.2-5B. Why? I don't know, I suppose it was just the first model I tried to train a lora for after a long time away. It seems to have gone fairly well? This model is much (much) more consistent at making breasts grow than the Hunyuan version, but I've really only tested it with image to video. It does fine with animated content or photorealistic stuff.

As far as I can tell, there are two main drawbacks: It does terribly when it has to generate nipples from nowhere (either because they were covered in the original image or because they get covered for more than an instant during the course of the video), and it doesn't do well with loose clothing. If you try to grow some boobs in an oversized hoodie for example, the hoodie itself will sprout breasts. Are these things that a v2 might improve upon? Honestly, yes. I didn't actually expect this training (which I did locally on a 4070) to work at all, so I didn't really put to much thought into curating the dataset. That being said, don't expect a new version anytime soon (or even ever, perhaps).

Having learned my lesson while posting the Hunyuan version, all of the videos posted in the carousel aren't upscaled, inpainted, or otherwise altered from their initial generation in any way, and all were generated locally using the aforementioned 12GB 4070 (and quite quickjly too, as each video taked only about 3-4 minutes). If you need to start with respect to a workflow, I co-opted this workflow by JCB2.

Anyway, thanks for giving it a try if you do. I really enjoyed seeing all of the stuff that you got up to with the Hunyuan version, so here's hoping that you're inspired to make some more cool stuff.

Hunyan Video: Hello everyone! Sort of a good news/bad news situation here. Good news: boobs will sometimes get bigger. Bad news: it's pretty inconsistent, I can't get it to play nice with other LoRAs, and I have no idea what I'm doing.

This was trained on a dozen or so small BE clips (256x256, 33 frames) using Musubi Tuner. I've never trained a LoRA before, and I really wasn't expecting to share this one, but I wound up getting a few (a FEW) good generations out of it so I thought I'd share. If anyone decides to give it a go, I'd recommend the following:

Keep the strength at around a 0.8. I have gotten results anywhere from 0.6 to 1.0, but any higher than that and things will go south real quick.

Use the keyword Br34st 3xpan5ion at the start of your prompt. Other than the keyword use natural language. Explain what it is you'd like the breasts to do as they get bigger. Burst out of clothing? Push a bra down? Bounce and wobble? I don't know if it actually does anything, but it makes me feel better if the gen turns out all right and I prompted it that way.

And... I dunno, have fun I guess? I look forward to seeing what all of you talented people can make of this.
