Free MiniMax H3 + ComfyUI handbook: 32 pages with prompts and 3 starter workflows

Antimatter654 · reddit · 2026-10-16

AntiMatter Comfy released a free English handbook for MiniMax H3, including a 32-page PDF, a Markdown edition with copyable prompts, and three original ComfyUI starter workflow JSONs (T2V, I2V, R2V), plus model links, setup checklists and troubleshooting notes.

Recommended first exercise: start with one short shot and one clear action, describing subject, action, camera and sound separately; keep seed and settings fixed while changing only the camera sentence; for reference editing, write down what should change and what should stay — a reference is conditioning, not a locked editing layer.
