Saya did "concept Painted clothes" https://civitai.com/models/20776/concept-painted-clothesbodypaint.
But I'm still struggling to make it work (in 1.4 or lower). EDIT: Now concept painted works a lot better in 1.5>. Those LORAS that modifies strutures like body parts, clothing, etc, are a hit and miss most times. But it works.

@schsch thanks for the heads up, I totally didn't find that lora. Yeah, I'm still getting the hang of sensing bad rng when different loras and checkpoints are involved.

I find a way to make that, you need two extension negpip/loractl to erase the "cloth" and give the cloth you want lower weight, and loractl to change lora weight in processing

for example:

1girl, (china dress:0.8), <lora:Bodypaint:[email protected],[email protected]>, (bodypaint:1.1), (cloth:-1)

Basically, it's using negpip to enhance the prompt erase effect, adding body paint effects in the middle to allow the AI to paint the clothes block onto the body after drawing the clothes block, and finally erasing the clothes block via neg weight "cloth"

Not perfect but usable,It's easy to achieve the target effect using cn's sketch model and SD's sketch inpaint.

This has more of a "melting clothes" effect than a perfect bodypaint but looks good. Also embeddings vs LoRAs would be good to swap out based on context (I think?)
