Breast Expansion WAN 2.2 i2v

V5 OUT NOW:

The new V5 model should improve many things about the model even tho there are still some problems that are hard to address. I tried to stop the models tendency for extreme jiggle and the characters always grabbing their breasts and I think I have mostly succeeded.

Generation Settings:
I use it with speed up loras on 768x1024 for 81 frames with a strength of 0.7

Prompting:

• Trigger the lora with --> "Br3ast3xpansion, her breasts grow"

• "Br3ast3xpansion, her breasts grow" should work for most users

• If you want the character to grab their breasts like in V1 try --> "grabbing breasts"

• The model is trained on the sizes --> "big breasts" "giant breasts"

Tips:

Choose a starting image that shows cleavage or parts of the breast so the models knows where to start. Otherwise the model has a tendency to often make the clothes semi . This behaviour is the most extreme when creating anime style videos especially with white shirts.

The model is not tested on t2v but since wan 2.2 is very capable this could work.

V1:
A new Breast Expansion Model for Wan 2.2. This model should work on Realistic and Anime images but I prefer the anime ones. This is only the first prototype trained on a big collection of lower quality videos and I will try to improve on this one by training it on the better videos.
