This LoRA is designed to generate crotch afterimage lines for male characters in hetero scenes.
It was trained on a total of 40 images: 20 original training images and 20 additional cropped close-ups focused on the crotch area to reinforce the concept. Since the dataset contains no semi-realistic images, this LoRA works poorly with FT models that produce realistic or semi-realistic skin textures.
This LoRA can be considered the successor to my 2way-afterimage v0.1.0, which is no longer maintained and is not recommended, but at the v0.0.0 stage, this new LoRA is still experimental.
It produces reasonably convincing afterimage lines from front and side views, but generating believable afterimages with a strong sense of close physical contact still requires some trial and error. Some training images also include ass ripple as a reaction to the afterimage effect, but its reproducibility is currently quite low.
Description
Changes from v0.0.0
The training dataset has been completely revamped, with most of the images replaced. The total number of images has been reduced from 40 to 30.
The proportion of cropped close-up images has been increased. The new dataset consists of 7 full-body images and 23 cropped images. As a result, the details of the afterimages have improved, and features such as skin tone, semi-transparent navels, and muscle definition are now more likely to be projected onto the afterimage.
The LoRA still tends to have poor compatibility with FT models and similar models, resulting in poorly defined afterimage details.
Most of the training images use a POV downward-looking perspective, or rear-entry and missionary positions viewed from the side. It does not work properly from viewpoints such as from below.
