Creating a Megastructure Generator in Houdini by Radu Cius

Tired of boxing out every building by hand? This tutorial shows you how to build your own megastructure generator in Houdini – set up the logic once, then get fresh building designs in a couple clicks.

🎯 What you’ll learn

• Build a custom procedural building generator from scratch in Houdini
• Work with nodes, parameters and procedural modeling workflow
• Use expressions, attributes and groups to drive parametric models
• Create modular massing, floors, facades and structural details
• Add randomization controls to generate unlimited building variations

✅ Requirements

• Skills: Basic familiarity with Houdini interface and 3D modeling concepts
• Tools: Houdini (Apprentice, Indie or FX version)
• Hardware: 64-bit system capable of running Houdini, 8GB+ RAM recommended

📝 Description

This is a straight build-along. You start with nothing and end with a working building generator you can actually reuse. No long theory dumps – you learn Houdini and procedural modeling by wiring it up yourself.

You will get comfortable with how Houdini thinks. That means scattering points, manipulating attributes, building groups for different parts, and using expressions to link size, floors, windows and details to simple sliders. Once that core is in place, small changes give you totally different silhouettes.

The real payoff is speed. Instead of pushing verts for sci-fi cities or background blocks, you dial in height, density and detail and let the parametric controls do the work. Perfect setup if you do environments, concept blockouts, or just want a solid procedural tool in your kit.

🧑‍🎓 Who this course is for

• Houdini beginners who want a practical first dive into procedural modeling
• Environment and hard-surface artists who need fast building variations for cities and concepts
