VNCCS UniCanvas

VNCCS UniCanvas is an integrated infinite-canvas image generation and editing workspace inside ComfyUI. It is designed for freeform creative work: generate anywhere, edit any region, build results across layers, and keep refining without being locked to a single fixed image boundary.

Key Features

• Infinite Canvas Workflow: Work beyond a single image frame and place generations wherever the composition needs them.
• Layer-Based Editing: Build images from separate raster and mask layers with visibility, opacity, selection, movement, and compositing controls.
• Generation Anywhere: Use a selected region as the generation target for new images, image edits, inpaint, outpaint, and full-area transformations.
• Mask and Object Tools: Paint masks, refine selections, and use SAM-powered object selection to isolate or remove parts of an image.
• Preset and Custom Models: Switch between built-in presets or use manual model selection for supported generation backends.
• Turbo and LoRA Controls: Use Turbo LoRA cards and a general LoRA Stack directly from the generation panel.
• Canvas Editing Tools: Move, transform, resize, snap, undo/redo, and manage generation results without leaving the node.
• Progress and Result Handling: Track generation progress and apply results back into the canvas as editable layers.

VNCCS Pose Studio

Example Workflows: QWEN · Klein9b

VNCCS Pose Studio is a professional 3D posing, framing, lighting, and pose-library environment running directly inside a ComfyUI node. It is designed for building high-quality pose/control references without leaving the graph: adjust the character body, pose bones interactively, frame the camera, tune lights, manage saved poses, and output single images or pose batches.

Key Features

• Interactive 3D Viewport: Pose the mannequin directly in the node with selectable joints, bone manipulation, transform controls, and full Undo/Redo support.
• Dynamic Body Generator: Fine-tune the character shape with sliders for Age, Gender blending, Weight, Muscle, and Height.
• Multi-Pose Tabs: Create multiple independent pose states inside one node, making batch outputs and pose sequences easier to build.
• Pose Copy/Paste: Transfer complex poses between tabs without rebuilding them from scratch.
• Modal Pose Gallery: Save, browse, load, and delete poses in a focused full-screen gallery instead of cluttering the main workspace.
• Pose Import/Export: Batch save and load pose data via JSON for reuse across workflows or projects.
• Tracing Support: Load a background reference image and align the 3D character to it for accurate pose matching.
• Precision Camera Controls: Set output dimensions, zoom, model rotation, and camera orbit with an integrated radar-style control.
• Viewport Frame Preview: Preview the final render boundary directly in the viewport so composition matches the output.
• Advanced Environment Lighting: Control Ambient, Directional, and Point Lights, including 2D radar controls for positioning point lights and radius controls for their influence.
• Keep Original Lighting Mode: Bypass synthetic lighting for clean flat renders, useful for ControlNet-style pose/reference outputs.
• Prompt-Aware Lighting Output: Generate descriptive lighting prompts that can be combined with your scene prompt.
• Custom Prompt Templates: Use tag-based templates such as <lighting> and <user_prompt> to control how the final prompt is assembled.
• Direct Sidebar Prompting: Add scene details in an auto-expanding prompt field directly inside the Pose Studio UI.
• Flexible Export Modes: Output poses as a list or as a grid, with configurable background color.

Additional Nodes

VNCCS Visual Camera Control

Example Workflow

An interactive node with a visual widget for controlling camera position. It is designed for intuitive angle control and prompt generation, especially for multi-angle LoRAs like Qwen-Image-Edit-2511-Multiple-Angles.

• Visual Widget: Select azimuth and distance with the mouse.
• Elevation Slider: Pick elevation from -30° to 60°.
• Trigger Word Toggle: Enable or disable the <sks> trigger from the widget.

VNCCS QWEN Detailer

Example Workflow

A QWEN-Image-Edit2511 detailer for enhancing detected regions such as faces, hands, and objects with vision-guided instructions.

• Smart Cropping: Automatically squares crops and handles padding.
• Vision-Guided Enhancement: Uses QWEN-generated instructions or user prompts.
• Drift Fix: Helps keep the enhanced area aligned with the original composition.
• Quality of Life Tools: Includes color matching, Poisson blending, and upscaling options.
• Inpainting Mode: Supports mask-based editing and filling black areas.
• QWEN Options: Supports QWEN-Image-Edit2511-specific options such as distortion_fix and qwen_2511 mode.

VNCCS Model Manager & Selector

Example Workflow

A system for managing and selecting LoRAs and checkpoints directly in ComfyUI, with support for Civitai and HuggingFace.

VNCCS Model Manager

The backend node that reads a HuggingFace-hosted model_updater.json and manages model downloads.

• Repo ID: Point the manager to your HuggingFace model repository.
• Downloads: Queue and download models in the background.
• Civitai Support: Use API key authentication for restricted Civitai models.

VNCCS Model Selector

The companion UI node for choosing models from the configured repository.

• Visual Card UI: Shows model name, version, status, and description.
• Smart Search: Opens a searchable modal model list.
• Status Indicators: Shows Installed, Update Available, Missing, and Downloading states.
• One-Click Install/Update: Install or update models directly from the selector.
• Universal Connection: Outputs a standard relative path string compatible with standard ComfyUI nodes.

VNCCS BBox Extractor

A helper node for extracting and visualizing crops when you need detected bounding-box regions without running a full face/detailer workflow.
