Krea Face Fixer is an image-to-image ComfyUI workflow for taking an existing picture and repairing or replacing faces without rerolling the whole image. You can take any image as well, even something you didn't create, and execute surgical-precision face changes on it. The seed stays frozen unless you take measures to randomize it, so it always functions like it's meant to do, without needless excess. Run only the stages you need. Have the metadata in there. Apply character loras only to the face you want, and not to the whole image.

Use Cases: I used it to fix up Serana's training data. You can use it to correct some bad faces on a character sheet or just add a variety of expressions. Or you can take a dataset that already has everything you need except another face, and give each image another face. Bulk loading is not included in this version, but I may come out with it soon.

Each face slot has its own prompt window and its own LoRA loader, so you can fix several faces in one pass with different targets. Detection is handled with SEGS pickers and a detailer array, the same pattern used in all MGHerder workflows so if you use my detailer arrays, it will feel very familiar.
