Installation

In Blender open Edit, Preferences, Get Extensions, then use Install from Disk and pick the hookah_generator zip.

Usage

1. Open the Hookah tab in the 3D viewport sidebar (N). With nothing selected, click the picture to choose one of the 49 designs, or browse the eight families, and add it at the 3D cursor. You can also use Shift+A, Mesh, Hookah.
2. The card at the top shows the design, its size and its face count. Surprise makes a new random hookah, Vary changes the proportions of the current one, the palette button picks a random finish and the arrow resets the design.
3. The icon tabs hold every setting: Vase (shape, glass, cut, water), Stem (style, chambers, hoses, purge valve, tray), Bowl & Coals (bowl, tobacco, heat management, coals, wind cover), Hose (cover, handle, drape), Look (condition, metals, colours) and More (tongs, LED, smoke, glow lights, detail, Convert to Mesh, Delete).
4. Every picture choice opens a gallery: click the picture to see all options, or step with the arrows.

Glass and water refract in Cycles and in EEVEE (the addon turns on EEVEE raytracing when it adds a hookah).
