BeltBuilder is a procedural geometry node system designed to generate complete conveyor belt systems. By defining a custom path, users can automatically create a conveyor assembly that includes moving belts, plates, and rollers. The system evaluates curves and support structures dynamically, offering optional structural additions like lamps, signals, and barriers.

The tool includes integrated animation controls that allow users to start, stop, or reverse the belt motion at will. It also features a transport system that moves target items from multiple sources to a destination, handling merges and splits at intersections using built-in pathfinding. A viewport visualizer is included to cycle through designated item groups for rapid previewing.
