Process - Use cut&paste training images to convince PonyXL to grab arm/shoulder instead of breasts. Then generate outputs and thicken the dataset for v2. First generation was trained using Blair Dame PonyXL character.
v2 - tends to add armbands to characters who wouldn't normally have them. So negative prompt "armbands" avoids adding armbands or noise around the point of contact.
v2 - tends to "steal" gloves from character LORA. You could avoid this with negative prompt. Or you can even add a LORA and try to get the gloves that you want on the POV hands. (v1 was super basic and tended to use hands that looked like the training data hands, and v2 seems to more fully recognize that these things really are hands)
