RsmFunbagsFP V1.0 works very well with FramePack. It is a Hunyuan Model, but I didn't see the kind of results in Hunyuan that I liked. It just happens to work well with Framepack.

UPDATE: CivitAI unpublished my RsmHanginFunbagsHy, RsmFunbags2Hy, and RsmFunbagsHy models, because I used a small amount of M4CROM4STI4 in the merges. I reached out to the owner of M4CROM4STI4, and requested permission....no response.

I will reformulate in the near future for Hunyuan. I have one that I am testing on FramePack that is showing extremely good results. I will release that model in the near future, once I am satisfied with it.

RsmSmallerFunbagsHy V1 is exactly what the name says. It is intended for small/average sized breasts with natural movement. It is a mixture of many things, and quite honestly, I've forgotten exactly which models I used. Initially, I created an interim model made from a random block level merge of 8 different small breast models. Then I added in a little "small and puffy style," and finally, I did a merge with Move_Enhancer.
