So, now the challenge is to create a prompt that reliably gets rid of the bag.

Extra credit for the prompt that keeps the bag but gets rid of all the clothes. :)

@tojg Lol.. He did have that one outfit where he was only wearing a towel(and I think underwear underneath).

As for taining, learned some since I made that comment, the guy should try masking out the bag. Or just mask out everything but the boy/outfits. Then make sure to properly tag the outfits. As for removing clothes, dual loras, and specific prompting works best. There's one lora on here for.. I think the name was hajame..

There it is. That one is one of the few that can do both small, and uncut, only issue is, it does have a habit of overriding the style and turning your character's into short/stubby-legged/fatty/babyface characters(fat babies! -- toddlers tbh..), so, use at a lower strength if you ain't into that.

Also, watch the main models/checkpoints that you use. Cuz those can(and will) seriously bias the generations towards females.. The FoxAI realism model works nicely, but not the 'verile' one, cuz that one will turn your characters into bulky men.

But if you aim to use illustrious, see about gettin a copy of the thrillustrious model. It's no longer on here, but it is on seaart, Though I wasn't able to get past the stupid 'subscribe for VIP' bullshit to click the download button, so I had to use a browser extension which allows me to right click and remove such annoyances, then I was able to get the newest version(already had 6.0 from when it still was on here).

mind you, those ones may lean towards female a bit too without some decent loras to counter it.. All I can say is, don't get too settled into any setup that isn't producing ideal results a fair amount of the time. If you're getting females in even 5/10 of your results, time to try something different. Also, avoid the terms beautiful or anatomy in your prompting at all costs if you don't want females. best to leave them out in general, cuz I've had my moments before learning that when I was just tryin to get some nice clean images with no sexualized females in them, and I was getting females in every single one with the term 'beautiful' even though I was specifically prompting for no humans at all. and with 'anatomy' I was getting in your face female close-ups.. It was super trollish and irritating..
