Pipe Network Generator - Procedural Pipe Routing & Fittings (Unreal)

Point to point, round what is in the way. Drop BP_PN_Pipe in a level, move its Start and End handles and add any points in between: the pipe finds its own way through them with an A* search on a 3D grid that keeps straight runs on the axes, goes round anything with collision, can prefer to run high under the ceiling, and turns as little as it can. It rebuilds in the viewport as you move the handles.

Every fitting in place. Long and short radius elbows, 45s, bent arcs, flanges and butt welds, caps, expansion loops, gate, ball, butterfly and check valves, gauges, drains and vents, labels or snap-around pipe markers in ASME A13.1 colors, hazard stripes, insulation jackets, floor stands, hangers, wall brackets, trunnions, and sleeves where a pipe passes through a wall. Cut corners to 45 degrees and slope drains.

Eight looks: industrial steel, painted, copper, PVC, rusted, glowing sci-fi conduits, cable trays and HVAC ducts, with eight presets. Bake a finished pipe into one actor, then Merge Actors for a static mesh.

Unreal Engine 5.8 complete project, Blueprint only, no plugins. Open the .uproject and press Play: one pipe routed round a few blocks, with a settings panel to try every option and the route search drawn on demand. Every graph is laid out in commented sections and every setting and function has a tooltip.
