Task Failed Successfully? This was meant to be a sleeves length LECO. It kind of still does that, it also seem to modify the hair, outfit and light from a summer-ish to a winter-ish appearance.
So it goes from a warm summer short haired appearance to a cooler winter long haired one. I might give the sleeves one another try tweaking it a bit, but this one was interesting enough That I can't consider it a failure.
LECOs are manipulated by their weight and normally need no triggers to use it, change their weight like this <lora:SleeveLenght_000000050:-1> to make the girl's hair and sleeves shorter and her clothes lighter <lora:SleeveLenght_000000050:1> to make her hair and sleeves longer and her clothes warmer, setting it to zero having very little effect on the prompts. Remember you can go further than -1 or 1!
