This LoRA was trained on 76 training images in which the breasts appear to move back and forth between two points through the use of a solid form and afterimages.
As a result, afterimages tend to appear in bottom-to-top, top-to-bottom, diagonally upward, or diagonally downward directions.
One important limitation is that, in v0.0.0, most of the training images feature vertical up-and-down movement. Therefore, this LoRA is not capable of reliably reproducing intense side-to-side movement from a direct side view.
