BV Node Pack adds visual regional prompting, model-specific regional attention, regional LoRA routing, sequential detailer workflows, Smart Pipes, structured prompt tools, Subgraph controls and deterministic workflow utilities to ComfyUI.

Note

BV Node Pack is developed with extensive generative-AI assistance. Product direction, architecture, review and real-workflow validation remain human-led.

Important

BV Node Pack 1.0.0 introduces Regional V3. The accompanying Wiki is online but still under construction, so missing screenshots or incomplete pages do not indicate missing runtime features.

Existing Regional workflows retain compatibility and supported node-local data is migrated when a workflow is loaded. Loading does not overwrite the workflow file, and deprecated Regional wiring is not silently rebuilt. Keep a backup, migrate any remaining legacy connections to the V3 resource flow, then save, reload and run the updated workflow once. Press Ctrl+Alt+B to toggle Regional Legacy Debug Mode when hidden legacy ports or V3 provider links are needed for inspection. The shortcut can be changed in ComfyUI Settings → Shortcuts.

Installation

Install BV Node Pack through ComfyUI Manager, or clone it into ComfyUI/custom_nodes:

git clone https://github.com/BlackVortexAI/bv_nodepack.git

Restart ComfyUI and hard-refresh the browser after installation or update.

Feature overview

Regional prompting and LoRA routing

Create named regions with layered geometry, prompts and stable identities, then compile them through native conditioning or supported model-specific attention backends. Regional V3 supports independently resolved workflow-local LoRA resources.

Read the Regional V3 guide →

Smart Pipes

Carry typed workflow state through wired or wireless branches while preserving stable slot identity.

Read the Smart Pipes guide →

Workflow Control

Switch named workflow stages deterministically between active, muted and bypassed states.

Read the Workflow Control guide →

Structured prompts

Encode, filter, route and decode semantic prompt blocks without fragile string replacement.

Read the Structured Prompt guide →

Subgraph interface tools

Project headings, dividers, spacers and controlled choices onto purpose-built Subgraphs.

Read the Subgraph Interface guide →

Latent utilities

Create deterministic latent sizes and transformations for reusable workflows.

Documentation and workflows

Detailed guides and references are maintained separately from the runtime repository in the BV Node Pack Wiki.

Only selected, verified examples are published in workflows.

Support

Report reproducible bugs and feature requests through GitHub Issues.
