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
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.
LTXV 2.3 - V1
Coming in late May/early June...
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.

More control over the type of expansion but still limited and explorative. Works together with most other growth/expansion LoRAs.

v1 and v2 are the same file dude ? on both high and low ????
They're not, but I forgot to add a "_v2" to the V2 files. Sorry, fill fix that!
Edit: fixed!
Is it possible to prompt for growth of a particular body part only? E.g. height growth without hips/thighs/breast growth.
That was the idea, but the training thought otherwise. Mind you I only spend very little time training this. I also don't have enough clips to really separate the concepts. Maybe V3 can do this.
A way to still achieve this is trying multiple times or use the TripleKSampler with a negative prompt.
I love this lora, but I have trouble forcing clothed transformations. I've tried including the 'expand inside her shirt' etc. prompts, as well as putting 'ripping clothes' and 'nudity' in the negative prompt, and varying lora weights, but my character consistently end up with shorts around their knees and shirts that disappear/shrink/tear. any tips to achieve clothed results like your examples?
Hm that should usually do it. Are you using any special version of WAN 2.2? Try to include "nipples, breasts out of her top" in the negative prompt. Are you using TripleKSampler, maybe increase cfg?
Also, sometimes https://civitai.com/models/1786139/bursting-out-wan especially the low noise can prevent nudity. Try with 0.5 strength.
Oops, I probably should have mentioned that I'm using an SVI workflow. I use the Wan2.2 Enhanced model, the no-lightning SVI Q6 and Q4 gguf versions. I may try the bursting out lora too, thanks for the recommendation, but I have a feeling it won't fix my cleavage-cutouts appearing... Sounds like this is probably a problem from my own environment rather than your model!
@sixpt55 ah okay. I haven't tested this with anything else than the standard scaled WAN 2.2 I2V, unfortunately. Adding the bursting out LoRA on top can definitely help with unwanted nudity.
I'm currently trying to train a final version of this with better prompt adhesion and control. So maybe that'll work for you then.
@cupra Thanks! I want to reiterate I'm loving the model and it works incredibly, it's just this one niche use case I'm fumbling with. Looking forward to any future iterations to tinker with!
