A developer showcased Muse-Studio-H3, a custom ComfyUI node that chains MiniMax H3 generations into continuous multi-chunk renders with no hard duration ceiling, freeing memory between chunks. The author rendered a short film locally on an RTX 5090, demonstrating consistency across six generations for scene, lighting, and characters. The concept is similar to H3 Director but with a distinct implementation, and the author plans to integrate it with Muse-chat.
