Puts your own character into an existing scene frame with one Qwen-Image 2.1 edit pass. The frame is the canvas: the pose, the other people, the camera, the light and the room stay; only the woman is replaced by the character on your reference picture. A depth map of the frame holds the pose and the sizes.The package is the working recipe, not only a graph: the standing instruction texts, the prompt template, the questions that let any vision model write the prompt for a frame, and the two rules that decide whether a swap comes out clean.WHAT IT DOES• Input: a scene frame, a picture of your character (portrait or full body), and four short text boxes.• Output: the same frame with your character in it, at the frame's own pixel size.• One pass, 6 steps (Qwen-Image 2.1 int8 + the Viggle turbo LoRA), no CFG.WHY IT IS MORE THAN A GRAPH• Classify first. A frame where the woman's face is not visible (back view, hidden face, head out of frame) must not get a face swap - it turns her toward the camera. The workflow has a separate hair-only mode for these frames.• One pass. A second full pass over the result degrades style and anatomy, so the graph is built for exactly one.• Keep rules. The instruction says what must stay exactly as in the frame, so the swap does not tidy the picture up.THREE MODES, ONE LINK TO CHANGE• A - face visible: the swap (default wiring)• C - oral scene: the swap plus an extra keep rule• B - no face: hair only, no face is ever drawnWHAT IS INCLUDED• character_swap_qwen21.json - the ComfyUI workflow (groups: Inputs, Depth, Models, Instruction + Prompt, Sampler, Output; notes inside)• character_swap_qwen21_api.json - the same graph in API format, for scripts• PROMPT_KIT.md - instruction texts, prompt templates with placeholders and one filled example, the vision questions, the decision rule, a per-frame checklist• <a target="_blank" rel="ugc" href="http://README.md">README.md</a> - requirements, step-by-step use, the three modes, scripting, tips, troubleshootingREQUIREMENTS• ComfyUI with the core nodes Text Encode Qwen Image 2.1 and Qwen Image 2.1 Cache (tested on 0.37.0)• Custom nodes: comfyui_controlnet_aux - only for the depth map (Depth Anything V2); it can be replaced by a depth map loaded from a file• Models (about 19.3 GB with the depth weights): qwen_image_2.1_int8_convrot.safetensors, qwen3vl_8b_int8_convrot.safetensors, qwen_image_2.1_vae_bf16.safetensors, Qwen-Image-2.1-viggle-turbo-v0.2.1-6step-lora-r128.safetensors, depth_anything_v2_vitl.pth (fetched by the depth node)• GPU: runs on 12 GB (RTX 3080 Ti) and 8 GB (RTX 3070 Ti) cards; 8 GB is the tight end. On 12 GB the full swap took 49-51 s and the hair-only mode 25 s.• This workflow is built for Qwen-Image 2.1 Edit. The model weights are not included and are used under their own licence - check it for your use.HONEST LIMITS• One woman per frame in this version.• The model works at about one megapixel; larger frames are resized back and come out softer than the source.• You fill the pose sentence and the details list yourself (two questions for any vision model are included). An automatic classifier is not part of the workflow.• The prompt kit contains explicit wording for adult scenes. Use it only with your own characters or with consent; adults only.
