ComfyUI-PackedPipes

ComfyUI-PackedPipes

A set of custom nodes that keeps ComfyUI workflows tidy by combining multiple links into a single pipeline link. This extension adds two nodes, Pipe Packer and Pipe Unpacker, to the utils category.

• Pipe Packer accepts up to 16 connections of any type.
• Pipe Unpacker restores the inputs of its connected Pipe Packer as outputs, in the same order.
• Supports rerouters and subgraphs.
• Pipe Packer supports custom input port labels ("Keep input names" option).
• Supports nesting: a packed pipe can be connected to another Pipe Packer.
• When an input port is connected, the Pipe Unpacker node automatically synchronizes with its Pipe Packer node.

[!NOTE] Renaming and removing Pipe Packer input ports is not available in Nodes 2.0 — ComfyUI does not expose these options in the new UI. To rename or remove a port, temporarily disable Nodes 2.0.

Installation

2. An example of nested Packers and Unpackers

3. A complex example

An example based on the Wan 2.2 14B I2V template, adapted to sequence multiple scenes into a video longer than 5 seconds. The last frame of each scene is passed to the next scene as the first image. Duplicate the second scene's subgraph to add more scenes; any unused scene can be bypassed.
