Style Transfer Prompter

🎨 Style Transfer Prompter Generate style-only prompts from a reference image for FLUX, Qwen and other Image-to-Image models. Unlike traditional image captioning, Style Transfer Prompter intentionally ignores the image content. Instead, it instructs a local VLM (Qwen3-VL) to describe only the visual style—brushwork, line quality, edge treatment, rendering technique, textures, and color palette. As a result, the target image keeps its original subject while adopting the artistic style of the reference image. ✨ Features ✅ Style-only prompt generation No characters, objects, poses, or scene descriptions—only stylistic attributes. ✅ Four analysis modes 🎨 Artistic / Illustration 🧊 3D / Render / CGI 📷 Photorealistic / Cinematic ✏️ Anime / Manga ✅ Identity preservation keep_identity helps preserve the identity of the target subject. ✅ Painterly edge detection painterly_edges describes unfinished brush strokes, watercolor bleeding, rough edges, and loose paint transitions. ✅ Color control keep_original_colors preserve the original colors of the target image or adopt the palette of the reference image ✅ Custom prompt extension extra_prompt appends your own instructions to the generated prompt. 📦 Dependencies This node requires: ComfyUI-QwenVL — local VLM for style analysis ( https://github.com/1038lab/ComfyUI-QwenVL ) ZImageResolutionScaler — automatic resolution matching ( https://civitai.red/models/2344436/z-image-resolution-picker ) FLUX 2 Klein 9B Distilled — Image Editing model ⚙️ Installation Download the archive.
