(see original for previous version info)

This lora is to produce the effect of the subject growing bigger. It was trained on mostly male furry videos, so it probably skews towards that in generation.

The alpha version was trained on a larger dataset that included more jerking and pulsing movements to indicate the growth, which tends to be overaccentuated in the generation.

The beta version was trained for more iterations on a smaller dataset that included less visible growth movements, so it tends towards generating things that look like they're just being scaled up.

V1:

This was my second attempt at combining everything into just one Lora you can use and not need to use any other alpha/beta/gamma with it, and I think it works decently well. It has the same trigger words as gamma.

clothes ripping / clothes ripping off
the room gets cramped
grows more muscular

They have varying degrees of success.

Note: each one you use increases the effect of the lora, and means you should use a lower weight. If you include the word "grow" multiple times, it seems to overexaggerate the effect and cause the subject to get really inflated/fat proportions.

Generation Tips:

It seems to need to be anywhere from 0.65 to 1.15, based on the image you're trying to animate. You can just use this one by its own.
This seems to need more steps when using the lightx2v/lightning loras, or else you get jerky movements. I typically end up using 10 steps, 5 High, 5 Low
I usually use Euler Simple
