Umbra Nodes
Umbra Studio custom nodes for ComfyUI metadata saving, Power Prompter integration, and workflow bridge support.
Nodes (21)
Name:0.8> in your prompt again — no loader node required
One CFG, five samplers — a single dial for the whole graph
Give your Flux.2 detail crops their own scheduler — not a one-size sampler
Frame Interpolate — smooth slow-mo without blowing up your VRAM
HiDream O1 detail crops need LCM-style sampling — this provider does the legwork
Ideogram 4's dual-model guider, wired into your detail crops
The detailer that fixes person, face, eyes, and hands in order — one node
A model upscaler that respects a maximum dimension — and never double-scales
A KSampler that tells the truth about what it ran
A Forge-style hires fix in one node — with an honest upscale list
KSampler Normal — the plain sampler that labels itself for clarity
A save node that writes your PNG, your workflow, and an A1111-readable settings string
The save node that figures out your prompt so you don't have to type it
One loader for checkpoints, diffusers, UNets, and GGUF — no juggling nodes
OmniGen2 detail crops with dual-CFG guidance — regular or nested
Power Prompter — the entire front half of a workflow in one node
Power Prompter Websocket — the node that listens to Umbra's prompt cards
The seed node that understands batches and repeats, so you don't have to
Soft Inpaint Composite — blend the fix in without ghosting the subject
Steps, defined once, everywhere — the boring node that prevents silent drift
The 'more pixels' pass that won't shimmer or rewrite your frames
Umbra Nodes
Umbra Nodes is the ComfyUI custom-node package used by Umbra Studio.
It provides Umbra metadata save nodes, Power Prompter bridge nodes, prompt/runtime helpers, and Umbra-specific workflow support for ComfyUI.

The Umbra UI detailer presents a stable person, face, eye, and hand refinement contract while keeping detector/SAM wiring inside Umbra Nodes. The upscale node uses a selected super-resolution model and applies a true maximum-dimension cap; it never enlarges an already-smaller model output a second time.
Umbra UI Dependencies
Legacy Anima LoRAs on Anima 2.9B
The Power Prompter and A1111 LoRA Syntax nodes automatically remap original 28-block Anima LoRAs when the connected model is a 40-block Anima model. This uses the layer positions recorded in the official expansion manifest. Existing model/CLIP strengths and prompt syntax remain unchanged. Text-encoder and LLM-adapter keys are not reindexed. No conversion files are written and no global ComfyUI loader patch is installed.
Native 2.9B and already-converted LoRAs pass through. Automatic legacy detection requires coverage of all 28 original blocks. Partial-layer LoRAs whose original architecture cannot be determined are rejected with an actionable error. Other model families and ordinary 28-block Anima retain their existing loading path. Remapping corrects layer correspondence; it does not guarantee identical visual results to the original Anima model, or compatibility with every LoRA variant.
After installing a release containing this change, restart ComfyUI. Umbra Studio installs/updates this package through its existing custom-node installer; a Studio-only update does not replace an older installed Umbra Nodes checkout.
The image detailer requires ComfyUI Impact Pack and Impact Subpack. Its balanced profile currently expects these model files in the normal ComfyUI model folders:
models/sams/sam_vit_b_01ec64.pthmodels/ultralytics/segm/person_yolov8m-seg.ptmodels/ultralytics/bbox/face_yolov8m.ptmodels/ultralytics/bbox/Eyes.ptmodels/ultralytics/bbox/hand_yolov8s.pt
The default image upscale profile uses
models/upscale_models/4x-AnimeSharp.pth and caps the final long edge at 3840
pixels.
Manual Install
Clone this repository into your ComfyUI custom nodes folder:
cd ComfyUI/custom_nodes
git clone https://github.com/Nocturne-Ai-Labs/Umbra-Nodes.git Umbra-Nodes
Restart ComfyUI after installing or updating.
ComfyUI-Manager / Registry
This repository includes:
pyproject.tomlfor Comfy Registry metadata.comfyignorefor registry package cleanup
Before publishing to Comfy Registry, make sure the PublisherId in
pyproject.toml matches the registered Comfy Registry publisher account.
Relationship To Umbra Studio
Umbra Studio installs and updates this package from the public repository into its managed ComfyUI runtime. Umbra Nodes is not bundled into Umbra Studio portable packages, which keeps one canonical source for both Umbra and ComfyUI-Manager installations.
