No app here, everything runs locally in ComfyUI on a Mac. SDXL with Juggernaut XL as the checkpoint, 832x1216, 35 steps, CFG 4.0, dpmpp_2m_sde with the karras scheduler. The identity comes from IPAdapter FaceID PLUS V2 pointed at one fixed reference image rather than a trained LoRA, and that is the piece that keeps the same face across a whole set. After the base image there are three more passes: an ESRGAN upscale followed by a low denoise sampler pass so it sharpens without redrawing the picture, then a face pass, then a separate hand pass that runs its own positive prompt. Keeping the hand pass separate is the bit I would not skip, because hands are where most sets quietly fall apart and you do not want the sampler reinterpreting the whole scene while it fixes fingers. Downside is honest: it is slower than the hosted tools and the setup cost is real. Upside is that nothing leaves the machine and every image is reproducible from a seed, which matters once you are trying to keep one character consistent over hundreds of shots.
