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.

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.

Smart Pipes

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

Workflow Control

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

Structured prompts

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

Subgraph interface tools

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

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.
