[Bug]: ComfyUI-LTXVideo doesn't show up in Missing nodes

[LukeG89]

I just noticed that if you import a workflow that contains ComfyUI-LTXVideo missing nodes, "Install Missing Custom Nodes" doesn't show the node (I remember a couple of issues about this problem in the ComfyUI repo).

But you can still find the node if you search it.

LTXV-Node.mp4

I also disabled all the other nodes, except for the manager; still the same problem.

Here's the workflow I used from LTXVideo repo:
ltxvideo-i2v.json

[ltdrdata]

This is a current scanner limitation of ComfyUI-Manager.
Nodes are registered using the @comfy_registry annotation, but these nodes are not collected.

Soon, ComfyUI will embed information about custom nodes used in the workflow itself.
ComfyUI-Manager will adapt to this by suggesting missing nodes based on this embedded information, rather than the node class name.

[LukeG89]

Ok, got it. This will also prevent "false" missing nodes like in this cases? (people just copy-pasting code from other custom nodes)

• When the node names are identical, there should be a warning prompt. #1362

And comfyui-tensorops when you miss ComfyUI-Florence2 or ComfyUI-segment-anything-2 (like in my video)

[ltdrdata]

When custom node information is included in the workflow, conflicts caused by names defined in NODE_CLASS_MAPPINGS can will be prevented.

Of course, for workflows created in the old way without custom node information, the ComfyUI-Manager can only suggest missing nodes using the old fallback method.

Gradually, workflows need to transition to the new format.

Ok, perfect! Thank you! 😄
