Pipe Gen is a procedural generator for creating pipes and railings in Blender. By attaching the modifier to edge geometry, users can extrude paths and automatically array custom profiles along straight sections and fillets. The tool supports custom pipe profiles and flanges, offering control over spacing, offset, rotation, scale, and random scattering along the straight segments.

The system includes a subdivision-ready pipe kit with pre-configured UVs, or users can input their own custom geometry. Features include automatic UV mapping with seam placement control, vertex group control for adjusting individual fillets, and the automatic generation of support loops to ensure the geometry holds its shape when subdivided.
