Fire Hydrant Generator

Fire Hydrant Generator builds photorealistic fire hydrants inside Blender, from the classic American dry barrel on a city sidewalk to a German underground hydrant under its cast iron lid, a Japanese pillar, a Victorian column or a rusted wharf hydrant. Pick one of 31 designs modeled on real hydrants, then change anything: every part is a number, a choice or a switch, and the hydrant rebuilds live as you drag.

Five kinds of hydrant cover the street: pillar hydrants (dry and wet barrel, European, Asian, vintage and industrial), underground hydrants with their lid and marker sign, wall-mounted fire department connections (Siamese), post indicator valves and rural dry hydrants. Outlets come with threaded, Storz, Guillemin and instantaneous couplings, caps, chains and valves.

Every hydrant is game-ready. Export for Games bakes the materials into a PBR texture set packed for Unreal, Unity or Godot, builds up to four levels of detail and UCX collision hulls, and writes GLB, FBX or OBJ in one click.
