Version 1
As is often the case, good enough is good enough.
This lora is design to make Pedal Pumping shots that can then be used with a video model to make pedal pumping videos. It's not perfect and fairly finicky, bit will at least transfer the image of the feet into a close up.
It struggles with bare feet and is biased towards heels, so that may need to be fixed after the fact. I've found it works best with either high resolution character sheets or close up feet focused shots.
I don't have a foot fetish (I would admit it shamelessly if I did) so I'm not going to play around with this too much, so I encourage you Foot Freaks (and I mean that lovingly) to offer tips and tricks in the comments.
