FLUX fully automatic hand and foot retouching provides options to switch between automatic masking and manual masking, as well as three options: retouching hands alone, retouching feet alone, and retouching hands and feet simultaneously, offering high flexibility. Note that if manual retouching is selected, you must apply a mask; otherwise, an error will occur during operation. If the automatic retouching effect is unsatisfactory, it is most likely due to an issue with automatic mask recognition, which can be adjusted by manually applying the mask.
