Load a body image and a head reference: it replaces the head with the reference's face and hair and keeps the body, pose, clothes, lighting and background. A built-in side-by-side preview shows body, head and result at a glance.This gallery: the character from my Katana video, made locally with Qwen Image 2.1 and kept consistent across every shot with this workflow (the Katana video is sponsored by Higgsfield): <a target="_blank" rel="ugc" href="https://youtu.be/ly6Mj0oFqU0">https://youtu.be/ly6Mj0oFqU0</a>Settings (already set):<ul><li>BFS V1.1 head LoRA at strength 1.0 (the V1.1 alternative is in the loader, switched off)</li><li>8 steps, CFG 1, sampler lcm, scheduler bong_tangent (from the RES4LYF node pack)</li><li>image 1 = body, image 2 = head reference; the swap prompt is already in the text encode node</li><li>CFG 1.2 was more than twice as slow in my tests with no gain in resemblance: stay at 1</li><li>Timed on an RTX 4000 Ada: about 45 s per swap</li></ul>Tips<ol><li>Use a sharp, front-facing head reference, and crop it so no props are in it (an uncropped reference put a second sword on my character's back).</li><li>Use a body image where the face is clearly visible (waist-up or closer); faces far away in full-body shots swap less well.</li><li>Qwen 2.1 can shift the whole image slightly (colours, softness) even for small edits; higher resolutions help.</li></ol>Models (Hugging Face):<ul><li>BFS head LoRAs (V1.1 + alternative) by Alissonerdx: <a target="_blank" rel="ugc" href="https://huggingface.co/Alissonerdx/BFS-Best-Face-Swap/tree/main">https://huggingface.co/Alissonerdx/BFS-Best-Face-Swap/tree/main</a></li><li>Qwen Image 2.1 Turbo by the Qwen team: <a target="_blank" rel="ugc" href="https://huggingface.co/Qwen/Qwen-Image-2.1-Turbo">https://huggingface.co/Qwen/Qwen-Image-2.1-Turbo</a></li><li>ComfyUI files (Turbo int8, text encoder, VAE) by Comfy-Org: <a target="_blank" rel="ugc" href="https://huggingface.co/Comfy-Org/Qwen-Image-2.1/tree/main">https://huggingface.co/Comfy-Org/Qwen-Image-2.1/tree/main</a></li><li>Low VRAM: Turbo Q5_K_M GGUF by Abiray: <a target="_blank" rel="ugc" href="https://huggingface.co/Abiray/Qwen-Image-2.1-Turbo-GGUF/tree/main">https://huggingface.co/Abiray/Qwen-Image-2.1-Turbo-GGUF/tree/main</a></li></ul>Custom nodes: ComfyUI-GGUF, rgthree-comfy, ComfyUI-KJNodes (side-by-side preview) and RES4LYF for the bong_tangent scheduler (ComfyUI Manager &gt; Install Missing Custom Nodes): <a target="_blank" rel="ugc" href="https://github.com/ClownsharkBatwing/RES4LYF">https://github.com/ClownsharkBatwing/RES4LYF</a>System requirements: NVIDIA RTX GPU, about 8 GB VRAM for the int8 Turbo or 6-8 GB with the GGUF, 20 GB free disk.Want more realism?
