    Overview

    A female bodies expanding into serious thickness. This model focuses mainly on thigh/hip growth, breast expansion and ass expansion, but can also do other things. Just play around with it.

    There is no trigger; use following descriptions:

    • Her thighs grow (massively)

    • Her breasts grow (massively)

    • Her buttocks grow (massively)

    • Her belly grows

    • Her height increases (dramatically) / her head hits the ceiling (this being replaced by the height growth LoRA)

    • Her clothes rip / tear / shred / tear open / rips across / leaving exposed

    Adding my T2V helper LoRAs will improve the quality and/or growth rate significantly. Also, using the TripleKSampler can greatly improve the animation quality, if you're using speedup LoRAs.

    Further descriptors can enhance the effect. Sometimes it can take a few tries to get it just right. These keywords can also be used in the negative prompt to weaken an effect.

    For more have a look at the example images/videos.

    H3 - V1

    This is an early I2V version so expect better textures, physics, and shapes in the future. Play with the strength; for breasts it seems to work better around 0.7, while for thighs and butts 0.9 works fine.

    • Training model: H3 FL2VA

    • LoRA strength: 0.5-1.0

    • Sampler: euler / res_multistep / res_2s+beta57

    • Steps: 20+

    Her thighs grow massively, stretching her shorts. She wakes up in shock, looking down at her thick thighs and wide hips.

    LTXV 2.3 Sulphur - V1

    Does work on LTX 2.5 with limitations.

    Intended to be used with a I2V LTX 2.3 10Eros workflow. T2V will yield unpredictable results.

    • Training model: LTX 2.3 Sulphur

    • LoRA strength: 0.5-1.3

    • LoRA strength high-res: 0.15-0.5

    • Sampler: euler

    • CFG: 3.0

    • Steps: 20+

    A candid shot of a woman standing in a bedroom. She's wearing a white bra and panties. She has blonde hair and a petite, slim body.
    
    Her breasts grow, overfilling her bra, forming a deep, spilling cleavage. She breathes heavily. Her tight bra covers her massive breasts, which spill over the top and sides.
    
    She looks at the camera, arms resting at her sides and says panicked and confused: "What did you do to me?"

    WAN 2.2 I2V - V2.9

    • Training model: WAN 2.2 I2V

    • LoRA strength: 0.5-1.0

    • Sampler: euler / euler a

    • Use TripleKSampler with 1/4/4 steps or no lightning LoRAs at all for quality.

    • I highly recommend using my T2V helper LoRAs linked below. Use their low-noise component for improved texture quality or their high-noise for better shapes and bigger expansions.

    I've been trying to find a lora with wan2.2 where the person bursts out a building from growth but that's rare to find material in itself. do you have any tips for me to get started training my first wan2.2 lora? I'm thinking in general I need to curate the dataset with like 5 seconds worth of those scenes.

    But would I need to have the resolutions all be the same? thinking 50 5 second videos dataset should be enough?

    Thanks in advance for any advices!

    That’s very ambitious! 50 clips would certainly be enough. They don’t have to be all the same resolution, WAN can handle variation there.

    The real problem will be temporal consistency, physics and preservation of details, because WAN wasn’t trained at all on this. It needs to learn several concepts from scratch (size difference, major destruction, fantasy physics).

    Your captions have to be precise, your clips varied and high quality.

    Yes, there’s already a beta version on my HuggingFace. Full release will be around the end of this month.
