Apparently, FLUX doesn't want to show boobs from behind. This LoRA will fix that. The version was trained to show the sides of large breasts from either one side or both sides. It was not designed to add nipples, so bring your own if you want them. There are a handful (pun intended) of other LoRAs that can do that.

Above are the first images that I generated with no skips/redos or anything. It works like a charm but prefers topless sideboobs vs sideboobs in a bra.

Side note: sometimes it's funny what gets labeled as R or X on Civitai. Above, picture 2 is R and picture 3 is X (I guess because of the panties, nevermind the tits).
