I’ve spent a couple hours researching a reliable and precise way to select a breasts size on NovelAI.
here is how I proceeded :
I don’t have the exact prompt, but I used the keywords from this danbooru image (top post of Hot section) and modified it a bit (removed the horns, the bell, ahoge, and “artist name” then added classic tags like “photorealistic).
I had my basic prompt.
Then I used always 2 tags in positive prompts for consistency in the generated image, and 1 or 0 tag in negative prompt.
Here is the order of adjectives used :
small < tiny < medium < big < huge
(yes tiny gives results bigger than small, not the opposite)
I also tried "flat breasts", "large breasts" and "extra large breasts" but it didn't seem to be much different from "small", "big" and "huge".
In order of appearances, here are the tags I used (a minus sign before a word means it was put in negative prompt section) :
small small -big
small tiny -big
tiny small -big
tiny tiny -big
tiny medium -big
medium tiny -big
small, small
tiny, tiny
medium medium -big
medium medium
medium medium -small
medium big -small
big medium -small
big big -small
big, big
big huge -small
huge big -small
huge huge -small
huge, huge
