LoadImageOutput_motorway_edition

Every once in a while a node shows up that's basically a remap: take an image that's already in the Motorway pipe, and write it back under fresh keys - IMAGE and MASK. That's LoadImageOutput_motorway_edition in a sentence.

It reads one key (image, by default) out of the pipe and stores it under both IMAGE and MASK keys. Why would you want that? Because a lot of nodes, including most of the Motorway-ed clones, expect their inputs at conventional key names. If some upstream node wrote your pixels under an offbeat key, this node is the bridge that re-labels them to the names the rest of your graph assumes - the IMAGE/MASK pairing in particular, since plenty of nodes take an image and a mask together. It's the pipe-world equivalent of a reroute node: nothing clever happens, but the plumbing suddenly lines up.

It's a genuinely thin utility. That's fine - a thin utility that saves you from renaming keys across a dozen nodes is still worth having in the toolbox.

The wrapper

• MOTORWAY 🚌💨 - the pipe. Required.
• INPUT_image_key (default image) - which key holds the image you want remapped.
• OUTPUT_IMAGE_key (default IMAGE) - where the image gets re-stored.
• OUTPUT_MASK_key (default MASK) - where the mask gets re-stored.

Both outputs land in the same pipe you fed in, and the only output port is the pipe itself. If you want to hand the result to a normal (non-pipe) node, pull either key back out with a Motorway AxB ramp.

Installing

Part of the Motorway pack:

cd ComfyUI/custom_nodes
git clone https://github.com/agilly1989/ComfyUI_agilly1989_motorway
# restart ComfyUI

Or ComfyUI Manager → search ComfyUI_agilly1989_motorway → Install. No model downloads, no extra pip dependencies.

Gotchas

• You need a MotorwayStart upstream to create the pipe, and something upstream that wrote the image key.
• Keys are exact strings - Key: 'image' doesn't exist in motorway means nothing upstream stored that key.
• Don't expect this node to do anything to the pixels. It's a re-label, not a transform. If you came here looking for a resize or a color op, this isn't it.
• Beta pack, as always: author's README says "IF THINGS BREAK ITS BECAUSE I BROKE IT," and generated clones have been toggled off in some releases. Missing from the menu after install is a version thing.

A node whose whole job is "put this here and also here" sounds silly until you're ten nodes deep and every key name is load-bearing. That's this node's moment.
