BB Nodes is an add-on that expands the Geometry Nodes workspace by integrating a custom category into the Add menu. It provides a toolkit of over 100 pre-built node groups designed to streamline procedural modeling workflows. The collection includes ready-to-use operations for common mesh manipulations that are otherwise complex to construct from scratch, such as inset, array, bridge, knife, and UV mapping.

The toolset also includes procedural modifier equivalents like bend, taper, screw, twist, solidify, and mirror. Recent updates have added advanced nodes for loopcut extrusions, geometry smoothing, wireframe generation, and CAD-style stretching, allowing for more complex procedural setups without building foundational math operations manually.
