What is it?

H3 Character Sheet Designer is a ComfyUI node pack for producing character reference sheets. It takes one character image and up to three optional part reference images, passes them to MiniMax H3's native image-reference conditioning unchanged, and lays out up to 13 views: six head views, three full-body views, front and back clothing, paired hands and paired feet or footwear.

The project provides a current v1.3.0 node and a previous v1.2.2 node, plus a supplied subgraph workflow template. Layout guides can be passed to the model or kept as display-only, and users choose a preset such as the seven-view hands-and-feet layout. Part prompts assign extra references to roles like same character, face, hair, outfit front or back, hands, or footwear.

The template requires native ComfyUI H3 support and rgthree-comfy for its Power LoRA Loader; the Designer itself adds no Python runtime dependency. Models and images are not bundled and must be downloaded separately, with the CLIP loader set to type minimax and an H3 text encoder selected.

Things to know

  • Model weights are not bundled and must be downloaded separately, with their own licenses and access requirements.
  • The template requires native ComfyUI H3 support and the rgthree-comfy node pack.
  • Results can still include human remnants, missing or duplicate views, and outfit/body confusion, and the README reports no proven major quality gain.
