    LTX 2.3 V2.5 UPDATE

    I have trained with a bit more variety, to get a more stable effect.

    Hope you like it, let me know in the comments :)

    Also check my updated base workflow with the new Ltx 2.3 1.1 distill lora

    LTX 2.3 UPDATE

    Yes made my first attempt on training a LTX lora. It clearly adds some nice bounce, but im not sure if its there yet. Let me know in the comments

    In doubt use my base workflow:

    WAN

    This lora is for animating bouncing breasts with Wan. Since I felt there was a lack of it here ;)

    Used I2V-14B-720P as base.

    Since ppl were asking about my training worklfow:

    I have used 7 videos with about 4 second length, with faces cut off. I have described what happens e.g.

    A girl with blonde extensions is standing in a hotel room, she wears black lingerie, her breasts are bouncing shaking or wobbeling up and down, her hands stand still, her face is cut off

    Then I used Musubi-Tuner with default parameters and trained about 32 epochs, with my 4090 it was done in about 35 min.

    That's all :)

    Thank you soooo much for this amazing work ai_build_art!!

    Folks: what are your impression thus far? Do the boobs bounce as well or better with the Wan 2.2 version? Share your impressions here!

    Well I've tried this fabulous Lora with Wan 2.2 by performing 100+ segments on my rented GPUs and I was soooo relieved to see it work on amazing Wan 2.2 which opens up so many opportunities!!

    However I could not help but notice that while the boobs do bounce nicely, they appear 'stiffer' than the 2.1 version. Have you noticed that too?

    Is there anything I can do with the Loral strength level or the prompt to 'add more jiggle'? :-)

    is it possible to make a wan 2.2-5B version for us small gpu ppl?

    I'm stupid so can someone help me out.
    How do i use this exactly ? Putting both high and low noise in the lora nodes with strength 1 and even adding prompt like jiggles or bounce etc. is not working for me.
    Do i need to do something else ?

    now we just need a WAN 2.2 T2V-A14B model version and the same applies to the bouncy walk lora too🥹

    Any possibility of porting this essential Lora to Wan 2.5?

    Are we supposed to use the High and Low together, like WAN high noise and low noise?

    Dunno why but this Lora keeps looping my vids. I have tested it non stop to find the culprit on this one. As soon I deactivated it ran fine. Anyone has the same problem?

    Strange, maybe try my reference workflow and see if it persists ?

    Could you perform Lora reshaping for fatty breasts? Fatty breasts have a higher proportion of fat, so they jiggle more when walking, and the surface has a ripple-like texture when bumped. Even a smaller D-cup can jiggle quite a bit. The Lora data seems to be based on data from glandular breasts, which don't have that ripple-like texture when jiggled.

    What should be the Strength settings on the HIGH/LOW loras? The breast movements in my tests are of tiny amplitude and are jerky - not at all like the big beautiful bounces I see in other people's pictures. I tried both 1, high:0.8-low:0.6 and similar but can't seem to get the same beautiful bounces like I see in people's pictures. Any help would be much appreciated! (Using I2V with lightning loras at 1, and NSFW lora at 1 (tried lowering - doesn't seem to affect much)).

    Check out my reference workflow, i used 1 as weight for high and low

    skooldickNov 4, 2025· 3 reactions

    for me, 0.6 on high/low gave me really good results when combined with an action lora (pov missionary at 0.7). a weight of 0.5 just gave the boobs a subtle bounce. can you share a workflow?

    tadirel864375Nov 6, 2025· 2 reactions

    @skooldick using Kijai's I2V workflow - got good results with 0.6/0.4

    any way to bouncy without clothing naked boobs?

    Does this Lora add wonderful boob physics PLUS the model bouncing up and down on her feet? (In some shots I want the amazing physics but not the bouncing up and down)

    When mixed with another lora, it slows down the motion. If I lower the lora strength to fix it, the boob bouncing diminishes. Any other fix?

    7021319Jan 22, 2026· 1 reaction

    Yes, use the old 720p lora. I just came here to find out why do I get better results with Wan 2.2 and the old lora.

    how can I run this myself in google colab

    This lora works most of time with certain motions of character. But it makes character body bouncing looking like dancing all the time. For example, I can't make a character idling with breasts bouncing because of the lora quirkiness.

    bnymnsntrkJan 23, 2026

    exactly. kinda ruins it most of the time
