I have been playing with superman for over one year. Many times I tried to generate other dressing with superman logo but the checkpoints always produce men with red cloak. That's why I make this LoRA - to put the superman logo everywhere I like without any unwanted elements.
Another attempt is to generate a superman bodysuit with a more futuristic style.
I tried to replace the prompt "superman" with "s-logo" so it will not trigger the checkpoint to generate any other elements associate with superman.
Hopefully it works in the way I want.
