Minimax Character Swap Workflow: The Green Dummy Strategy

lhg31 · reddit · 2026-08-24

A user shares a specific workflow for character swapping in Minimax video generation using a "green dummy" strategy. To avoid Minimax's tendency to morph facial features when swapping similar characters, the workflow first replaces the original character with a chroma-key green crash-test dummy, then swaps the dummy with the desired character. This preserves the target's features. The author provides a detailed ComfyUI workflow (Pastebin link), recommends using the 'Balance' sampling mode, and notes that monitoring the preview node is crucial—if the overlay isn't visible in the first step, the swap will likely fail.
