真·凹陷乳头，隔着衣服能看到而不会有明显乳晕和透肉。我觉得要是凸点算不适宜内容的话，那反过来，凹点不就应该是安全的级别对吧？

Real covered inverted nipples without obvious areola and make clothes more opaque. I think if the nipple bulge is not suitable in public, then as opposite, the covered inverted nipple, should be rating safe, right?

触发词是InvNp但有时候也得需要inverted nipples。如果加了inverted nipples，乳头就会被底模原本的凹陷形状影响从而变得没那么光滑。

• 如果你不想要那种被乳晕包裹的可见乳头，让它完全陷进去，在负面词里加nipples out

• 如果你想去掉乳晕，在负面词里加pink areolae,puffy areolae

• smooth areolae, 能让乳晕变得没那么明显

• 如果凹陷乳头出不来，加正面词：inverted nipples, covered nipples,

The Trigger Words is invNp, but sometimes inverted nipples is also necessary. If you add inverted nipples, the nipples will be influenced by the "original" inverting form in your checkpoint and become not ideally smooth.

• If you don't want the nipple surrounded by areolae to be visible, make it completely sink into the areolae, then add Negative prompt：nipples out,

• If you want to remove the areolae, then add Negative prompt：pink areolae,puffy areolae,

• smooth areolae, can help make areolae less obvious

• If the inverted nipples don't appear, then add Positive Prompt：inverted nipples, covered nipples,
