feat/model3d-input-encoder
Adds the symmetric client-side encoder for `File3D` values so a remote node descriptor can declare a `MODEL_3D` input and consume a 3D mesh from an upstream local node (e.g. `Load3D`, `TencentTextToModelNode`, `MeshyTextToModelNode`). Mirrors the existing AUDIO encoder (`encode_audio_input`, `is_audio_input`) and VIDEO encoder (`encode_video_input`, `is_video_input` — PR #19) added at `comfy_remote_nodes/serialization.py`: - `encode_model3d_input(file3d)` reads the primary mesh bytes via `File3D.get_data()` (returns a `BytesIO`, per `comfy_api.latest._util.geometry_types.File3D`) and emits a `{type: "model_3d", encoding: "glb_inline", data: b64, format: ...}` envelope. `encoding="glb_inline"` is the generic single-file inline encoding the server-side decoder (`decode_model3d_envelope`) already dispatches on; the decoder hands the bytes to `File3D(BytesIO(...), format)` regardless of whether the actual format is glb / obj / fbx / etc., so the encoding name is a logical "inline single-file 3D" tag and the `format` extra picks the file extension at decode time. - `is_model3d_input(value)` duck-types on the `format` string attribute + `get_data` callable. Both are present on the upstream `File3D` class and the `BundledFile3D` subclass built lazily in `_bundled_file3d_class()`. Avoids importing `File3D` at module load (which would pull torch via the `comfy_api` tree). - `_encode_one` in `proxy_node.py` dispatches AUDIO / VIDEO before MODEL_3D as defense-in-depth (the `VideoInput` shape — `save_to` + `get_duration` — does not expose a `format` string property, so VIDEO and MODEL_3D values don't collide either way). Multi-file bundles (`BundledFile3D`-style values where every companion file matters — e.g. an OBJ with sibling .mtl + texture PNGs) are intentionally not supported on the encode path in this PR: the first server consumer is the Tencent Hunyuan3D MODEL_3D-input node family (`TencentModelTo3DUVNode` / `Tencent3DPartNode` / `Tencent3DTextureEditNode` / `TencentSmartTopologyNode`), and the upstream upload helper `upload_3d_model_to_comfyapi(cls, model_3d, file_format)` only uploads a single file (`model_3d.get_data()`). Bundle encode (`bundle_inline`) lands when a partner node actually needs the companion bytes. This unblocks 4 Tencent Hunyuan3D nodes (out of 6 in the module) that were deferred to a follow-up PR — see matrix coverage TODO #6. First server consumers ship in a paired comfy-rnp-server PR (TencentModelTo3DUVNode_RNP + Tencent3DPartNode_RNP).

comfy-remote-nodes
ComfyUI custom-node package that fetches node descriptors from an RNP/1 (Remote Node Protocol v1) server and exposes them as native V3 nodes inside ComfyUI.
The reference server lives at
Comfy-Org/comfy-rnp-server
(private). This client is intentionally provider-agnostic: any server
that speaks RNP/1 can publish nodes through it.
Install
Clone into your ComfyUI custom_nodes/ directory:
cd ComfyUI/custom_nodes
git clone https://github.com/Comfy-Org/comfy-remote-nodes.git
(The directory name on disk doesn't matter — ComfyUI loads the package
via spec_from_file_location, so comfy-remote-nodes/ is fine.)
Configure
Point the extension at one RNP server URL via env var before starting ComfyUI:
export RNP_SERVER_URL=http://127.0.0.1:9190
python main.py
If RNP_SERVER_URL is unset, the extension registers zero nodes and
logs a single line — ComfyUI starts normally with no remote nodes.
What works today
- Manifest + capability handshake
object_infofetch and dynamic V3 class generation (with ETag conditional GETs)- Sync
executeand asyncexecute_async+ poll/cancel - Image / mask / audio / video envelope encode + decode
- Presigned upload helper for >8 MiB inputs
- Tier 3 (recent):
TASK_LOSTdetection with idempotent resubmission — survives an RNP server restart mid-task without losing the workflowSERVER_BUSY/MAINTENANCE503 envelopes treated as rate limits withRetry-Afterhonoring and friendly per-second progress text ("Server busy, retrying in 30s...")- Out-of-band
url_fetchfor URI-only output envelopes, driven by the descriptor'sremote.url_fetchpolicy - Per-poll auth refresh so long-running tasks can rotate tokens
What does not (yet)
validate_inputs/fingerprint_inputs/check_lazy_status— the server returns501 NOT_IMPLEMENTED; the client falls through to ComfyUI's defaults- Multi-server config file (
comfy_remote_nodes.yamlor similar) — today's setup is one server per ComfyUI process via env var - Streaming execute (server-sent events for incremental previews)
