This workflow relights an illustrated character to match a new background plate and merges them into a cohesive keyframe. The heavy lifting is packaged inside a Subgraph node (type ID: 9e3c3756-d15f-4361-8e99-c35673036e68), so you only interact with a few clear inputs and controls. You provide a character image and an environment image via LoadImage nodes, drive the look with prompt text (see the in-graph Note/MarkdownNote), and export results with SaveImage.

Technically, the Subgraph stacks an illustration LoRA for style cohesion with a relight LoRA that adapts shading and color to the environment. The subgraph handles conditioning, relight guidance, and foreground/background compositing, exposing simple strength sliders and merge options so you can balance “style” versus “lighting” without touching the internals. Notes in the graph include Chinese prompt text—keep those characters intact and append your own edit instructions after them to refine light direction, mood, color temperature, or rim light accents. For local users, ensure any referenced text encoder files (e.g., qwen_2.5_vl_7b_fp8_scaled.safetensors) are available so the subgraph can encode prompts as intended.
