Output Image

If you searched ComfyUI's node menu for this one and came up empty, that's not a bug on your end - RiceRoundOutputImageNode is filed under the category __hidden__, which in ComfyUI means it's deliberately excluded from the Add Node search and browse menu. You can't drag this one in by hand the normal way. Given that, and given its schema, the far more likely explanation is that it's inserted into a graph programmatically - most plausibly by RiceRound's own platform tooling, at execution time, as part of how a published workflow reports its result back - rather than something you're expected to build with directly.

Why document a node you can't add

Because it still shows up in search results and in exported/shared workflow JSON, and if you're trying to understand a RiceRound-published workflow someone handed you, or you're debugging why your own graph behaves unexpectedly after a publish/run cycle, it's worth knowing this node exists and what its fields imply, even though you won't be the one placing it.

The fields, and what they suggest

• images (required, IMAGE) - the result image.
• task_id (required, STRING, default empty) - a field name that strongly implies this node is meant to be populated per-execution, associating a specific output with a specific run of the published workflow. That's not something a human fills in by hand for a one-off local test; it reads as infrastructure plumbing.
• template_id (optional, STRING, default empty) - ties the output back to a specific published template, echoing the same template_id concept used by RiceRoundEncryptNode (RiceRound Publish) and RiceRoundDecryptNode (RiceRound Cloud).

No outputs, and it's marked is_output_node - a terminal node, same shape as RiceRoundEncryptNode, just automated rather than manually placed.

Installing it

You don't do anything differently for this specific node - it comes with the pack. ComfyUI Manager: search "RiceRound," install, restart. By hand:

cd ComfyUI/custom_nodes
git clone https://github.com/RiceRound/ComfyUI_RiceRound

then restart ComfyUI. No dependencies or model downloads are documented in the README for the pack as a whole.

Common issues & troubleshooting

You can't find "Output Image" in the node search and want to add it manually. You won't be able to, by design - it's hidden from the menu. If you're trying to build a workflow that reports results back to RiceRound's platform, that's what RiceRoundEncryptNode (RiceRound Publish) is for; this node isn't the one you reach for directly.

A shared workflow JSON someone gave you contains this node and ComfyUI complains it's missing. That points at the same root cause as any missing-custom-node error: the recipient doesn't have ComfyUI_RiceRound installed. Install the pack the normal way and the node becomes available for ComfyUI to load, even though it still won't appear if you go looking for it in the Add Node menu afterward.

You're trying to reverse-engineer exactly what task_id and template_id do. The README doesn't document this node individually - nothing in it beyond the schema is public, and there's no per-node reference on RiceRound's hosted docs site either as of this writing. Treat the reading above as an informed inference from the field names and the node's hidden, output-only shape, not a confirmed spec.
