Masked LoRA Image Snapshot (internal)

If you found this page, it's probably because "Masked LoRA Image Snapshot" turned up in your node search while a Load LoRA Masked workflow was open. That's expected, and it's the closest thing this node has to a purpose in your life: it's the internal plumbing behind Load LoRA Masked's mask editor, and it is not meant for you to wire into a graph.

The display name even says so - "(internal)". In the pack's source it's a tiny output node: one required IMAGE input, no outputs, CATEGORY = "_internal", which is ComfyUI's convention for "hide this from the normal add-node menu." It exists as a private snapshot sink.

What it actually does

When you open Edit mask on a Load LoRA Masked node and the editor needs an upstream preview, it offers Run upstream. That queues a tiny private prompt containing only your connected IMAGE ancestors plus this snapshot node - deliberately never your downstream sampler. The snapshot node then takes the first image of the batch, converts it to a PNG, saves it into ComfyUI's input folder under wepenerd_masked_lora/, and hands the preview back to the editor so you can paint over the right image.

That's the whole job. It grabs a picture, shows it to you, and gets out of the way. If you were to drop one into a workflow yourself, it would dutifully snapshot whatever IMAGE you feed it and nothing else - it has no result, so nothing downstream can connect to it. There's no scenario where you want that in your final graph.

What you actually came for

If you're here because you saw it in the Load LoRA Masked workflow, the answer is: ignore it. The mask editor inserts and removes it on its own while it fetches a preview; it isn't meant to persist in your saved workflow. If you delete Load LoRA Masked and the snapshot reference vanishes with it, that's correct behavior, not breakage.

Install it the same way as the rest of the pack (ComfyUI Manager, search WepeNerd, or):

cd ComfyUI/custom_nodes
git clone https://github.com/WepeNerd/ComfyUI-WepeNerd.git
cd ComfyUI-WepeNerd
pip install -r requirements.txt

then restart ComfyUI. The node comes along for free whether you ever see it or not - it's registered in NODE_CLASS_MAPPINGS like everything else, which is why search can surface it at all. Knowing it's scaffolding is the whole useful fact here. The node you actually want is its boss: Load LoRA Masked, the Krea 2 regional-LoRA loader this snapshot serves.
