Has anyone tried training a LoRA or Dreambooth using PNGs of a subject with a transparent background (essentially subject cut out and nothing behind)? I've tried with white background and backgrounds of random colors, both successful to remove associating the training with the background and focus more on the subject, however im curious if anyone has already tried this and could speak about the results
EDIT: When using ohwx man within a prompt, the random color background works quite well. However I just tried a simple "(ohwx man:1.3)" prompt and it mostly worked well however I did receive one photo that was just a purple background, so thats worth noting
