JZL - 🔗 MiniMax H3 参考总线（解包）

"JZL - 🔗 MiniMax H3 参考总线（解包）" (Reference Bus Unpack) is the receiving end of the pack's reference bus. It takes a single JZL_REF_BUS wire - the bundle created by the "参考总线（打包）" (RefBusOut) node - and fans it back out into the 48 fixed ports: 角色A–角色H, 场景A–场景H, 道具A–道具H, 音频A–音频H, 视频A–视频H, plus each video's soundtrack 视频A（音频）–视频H（音频）.

In a workflow that stages a bunch of character/scene/prop/video/audio references, the pack side keeps the graph clean by collapsing everything to one wire; this node is where that wire becomes useful again, feeding individual reference images and audios into the encoding path.

How it works

Mechanically it's the inverse of the pack node: it takes the bus dict (the custom JZL_REF_BUS type, force-input so it only accepts a genuine bus), reads each of the 48 fixed keys, and returns them in the canonical order - characters, scenes, props, audios, videos, video soundtracks. Ports that were None at pack time come back None. It does no processing, no resizing, no scheduling; the docstring is blunt: "只做传输" - it only transports.

Outputs are the 48 fixed ports, typed by name: IMAGE for the character/scene/prop/video slots and AUDIO for the audio and soundtrack slots.

How to install it

Part of the JZL-MiniMax-H3 pack - ComfyUI Manager, search "ComfyUI-JZL-MiniMax-H3", or:

cd ComfyUI/custom_nodes
git clone https://github.com/wjluoxiao/ComfyUI-JZL-MiniMax-H3

Restart. No extra dependencies.

Common issues

The ordering matters. The 48 outputs follow the fixed BUS_KEYS order, so if you're building a workflow by port name rather than position, read the labels - 视频A（音频） (A's soundtrack) is not the same slot as 音频A (a standalone reference audio), and mixing them up is the classic way to get a silent segment with the wrong or missing sound. Also note this bus is deliberately incompatible with the slimmer JZL_REF2VA_BUS (18 ports) used by the ref2va encoder - the types don't cross-connect, which is the point. If your encoder only accepts ref_image_0…8 / ref_audio_0…2 style inputs, you want the pack's ref2va bus pair instead.
