V2 DESCRIPTION Whereas v1 was really good at porn it can be improved in many ways. V2 brings about these changes at the expense of losing a little quality of the porn side (harder to get certain things done or it does not look that perfect, e.g. poses, cum, etc.).
v2.0 excels in better quality and variety of pictures at the expense of losing some of the porn-related aspects' high level.
people are much more beutiful than before
eyes are much better
texture and photorealism improved
easier to prompt and prompts are more followed (v1 has the tendency to not to follow some parts of prompts)
richer database --> better quality pictures, more details, wider range of images, wider range of styles
negatives and image improving prompts are hardly needed if at all
SETTINGS:
DPM++3M SDE Exponential, CFG: 4-6, steps: 30-40
DPM++2M SDE Heun Exponential (or Karras), CFG: 4-6, steps: 30-40
The best way is to start with no negatives and image improving prompts and step-by-step building it up.
