Subtle Nipples / 胸ポチ [Illustrious]

This was an experiment to create a more natural looking braless effect, independent of the artstyle. Basically, this should be similar to the 'no bra' tag in concept but the image generation won't try to take the character's clothes off half the time. I hope you find it useful as well.

To use, simply include the trigger word on its own for a very slight effect on breast shape, or combine it with any other breast or clothing related tags and see what it does. It's intended for clothed images so I have no idea if it will do anything at all for nudity.

I increased the size of the dataset by quite a bit, so the effects should be a little more visible without having to mess around with the weight so much. I added some useful tags to the trigger words section, but more than just those should work with this LoRA. It also appears to work better on breast sizes other than big ones now.

It's still pretty, well, subtle. I'm leaving 1.0 up as well so use whichever you prefer.

Tips

~ If the breast size is left unspecified in the prompt this may randomly give the subject a much larger bust, so if you don't want surprise hooters don't forget to prompt for the size you're after.

~ You can use the LoRA weight like a slider to increase/decrease the amount somewhat. May be more prominent on bustier characters.

~ At low weights the effects may only be apparent when the viewing angle is from the side, above, or below.

~ Use with associated tags to adjust the results. For example:

subt13_n1p5, impossible shirt, covered nipples

~ Trained on a mostly anime dataset but the main purpose of the LoRA works even at very low weights if you're trying for a non-anime style.
