Custom nodes:
  - Deno Custom Nodes (MiniMax H3 Acc LoRA Loader): https://github.com/Deno2026/comfyui-deno-custom-nodes  (ComfyUI Manager > Install Missing Custom Nodes, or git clone into ComfyUI/custom_nodes/)
  - ComfyUI-VFI: https://github.com/GACLove/ComfyUI-VFI  (ComfyUI Manager > Install Missing Custom Nodes, or git clone into ComfyUI/custom_nodes/)
  - ComfyUI-VideoHelperSuite (Video Combine): https://github.com/Kosinkadink/ComfyUI-VideoHelperSuite  (ComfyUI Manager > Install Missing Custom Nodes, or git clone into ComfyUI/custom_nodes/)
  - ComfyUI-KJNodes: https://github.com/kijai/ComfyUI-KJNodes  (ComfyUI Manager > Install Missing Custom Nodes, or git clone into ComfyUI/custom_nodes/)

How to use:
  1. Install the custom nodes above and restart ComfyUI.
  2. Download the model files into the folders listed. The Acc LoRA can also go in ComfyUI/models/minimax_h3_acc_loras/.
  3. Drag MiniMax_H3_Ref2VA_Acc_8Step_Workflow.json onto the canvas and re-select the LoRA if it shows red.
  4. Pick your reference image(s), edit the prompt and queue (euler / simple, 8 steps, shifts 12 / 3).

Notes:
  - The Deno Acc loader refuses sigma shifts other than 12.0 / 3.0, so do not add extra shift nodes.
  - For FL2VA use MiniMax-H3-FL2VA-Acc-8Step.safetensors with the FL2VA base model instead.

Model weights are not included. Each model keeps its own licence; check the model page before commercial use.
