This Lora is created to simplify the prompting of a pose that is actually not easy to get on Krea2, or at least not that easy for me, but I'm just barely north of literate on the prompting scale. The Danbooru tag that generally spits it out just fine in Illustrious or Pony top-down bottom-up doesn't have quite as much impact in Krea as it does in those other models, so you end up with some long-ass wordy description for "get her ass up".

Krea also has a noticeable aversion to female...uh...parts, from certain aspects, this Lora does seem to positively impact the aesthetics of the...parts.

Usage note for V1-Krea2: Due to the sample data being primarily 16:9 (widescreen/landscape format) this works better at a similar aspect ratio. If you're not seeing what you'd expect, shift your width:height to something like 1280:1024 or 1440:1024.

V2 Update

After some very useful user feedback, I tailored the dataset and cropped more diligently to provide a more reliable representation at all aspect ratios. From what I can tell, it worked.

Example prompt:

A high quality ass_up_presenting photo of a beautiful woman.  

The photo is a full body shot of her from the front.  

She has brown hair slicked back.  She has striking blue eyes.

She is looking at the viewer with parted lips, her tongue touching her teeth. 

She is wearing a hot pink highleg thong and white tank top.

She has a narrow waist and very arched back.  She is posing enticingly, her round ass up and legs spread, legs on the floor, breasts pressed on the floor.  Her skin is smooth and flawless, she is a sexy woman in her late 20s.

She is on her knees, top-down bottom-up, showcasing her flexible body presenting her ass.

She is in a suburban mall.
