- Download the MiniMax H3 diffusion model file (such as the 12.5 GB W48 version for consumer GPUs) and place it into `ComfyUI/models/diffusion_models`.
- Obtain required text encoder models and VAE weights and save them into their respective `ComfyUI/models` subdirectories.
- Load single or multiple reference images into the ComfyUI workflow nodes to perform upscaling, lighting correction, or style transfers.
