In my experience, H3 doesn't very well interact with object morphing into each other out-of-the-box.
This LoRA, fine-tuned on the transfomation-rich plasticine/claymation cartoon "Last Year Snow was Falling" (LYS) steers the model towards that "plasticine"-melting feel where the object is seemingly crushed and almost manually reshaped into a new object.
This LoRA is preliminary (or maybe not), because it trained for ~9 hours for 84 epochs and then it triggered the circuit breaker and I wasn't able to resume it properly, so maybe more train is needed, but it already works good in my opinion. If it's good, I will publish it to my CivitAI.
For now, enjoy!
Example prompt:
The LYS-style transformation video begins with a cup of coffee. Then suddenly the cup of coffee plasticine-transforms into a realistic parrot.
The two necessary trigger words are: "LYS-style", "plasticine-transforms".
Trigger words
You should use LYS-style to trigger the image generation.
You should use plasticine-transforms to trigger the image generation.
