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.Minimax H3Surprisingly, the base model already has decent knowledge of growth and stuff. I tried training a lora for it using the same dataset as the previous versions. The effect seems slight, and more of a polish than teaching it a new trick.For 0.9, I attached a few different epochs for the same model, pretty much just different amounts of training. I typically only used the 1000 step and 1500 step trained lora, but theoretically you should be able to get a stronger effect with the 2500 step one i also attached. Keep in mind, the more steps trained on in the lora you use, the less flexibility the model seems to have. (ie. the growth effect is slighter in the 1000 trained lora, but the overall quality seems better.)I included two different versions: one trained on ref2vid and one on fl2vid. It seems like both work on either diffusion model, but you do get a bit better results using the right lora with the right model.LTX 2.3There are no explicit trigger words, but you can include phrases like: "he grows bigger", "you can hear his body stretch as it grows", "expanding in a cramped room", which correlate to phrases used during training.Admittedly, there's room for improvement with this lora. The training trends are a lot more different than for Wan. At some point, training for more steps gives a worse result and reduces other dynamic movement. I thought it was at least worth sharing to give people a chance to play around with it, since I already spent the time and money to train it, lol.I use it with a lora weight or 0.9-1.25. It's possible you can get better results if you combine with other LTX movement or adapter loras.WanThe 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.Wan I2V Example ComfyUI Workflow: <a target="_blank" rel="ugc" href="https://pastebin.com/jrBihCYA">https://pastebin.com/jrBihCYA</a>Alpha &amp; BetaGeneration Tips:<ul><li>I've noticed that using a mix of both alpha and beta is usually what you want to do. I typically use 0.65 of beta and 0.55 of alpha. Trying to get a sum of a little more than 1 seems to be a good idea, but play around. That means you'll be using four loras for one generation: the high and low alpha and the high and low beta</li><li>There's no specific trigger word(s), but you may need to use phrases like "grows bigger"/"grows more muscular"</li><li>If your generation seems to have a lot of jerky movements or "jumping", try lowering the weight of just the LOW lora(s) used.

You can use just the gamma lora, but it seems to work differently with different images. I also added some "sub-concepts" you can try to also invoke with specific phrases. Using them also seems to over-accentuate some of the movements, so if the video gets more janky, don't use them.<ul><li><code>clothes ripping</code> / <code>clothes ripping off</code></li><li><code>the room gets cramped</code></li><li><code>grows more muscular</code></li></ul>They have varying degrees of success.Generation Tips:<ul><li>It seems to need to be anywhere from 0.65 to 1.35, based on the image you're trying to animate.
