3DT Stairs Generator – Blender Geometry Node Procedural

🎥 Demo Video

🛠 Update Geometry Node

Design functional or stylized stairs of any shape using the 3DT Stairs Generator — a flexible, curve-based system for Blender 4.0+.

Use paths or bezier curves to create straight, circular, or spiraling staircases with adjustable width, height, materials, base, handrails, and pole frequency. One of the most beginner-friendly yet powerful stair generators available.

🎯 Key Features

Draw Straight or Curved Stairs with Ease
Use paths for linear stairs or bezier curves for fully curved setups — handles allow precise control.

Material Override and Quick Switching
Change materials for stairs, base, handrails, and poles independently — ideal for rapid iteration.

Modular Base and Stair Width Controls
Customize stair depth, overhang, riser height, and base width separately for maximum flexibility.

Handrail Radius, Resolution, and Tilt
Control curvature, smoothness, and sloping of handrails on either side — mirrored or unique.

Pole Frequency and Offset Logic
Set poles per step, per few steps, or at offset heights — perfect for realism or stylized decoration.

🔥 Why You'll Love It

Perfect for Architecture, Interiors, and Games
Create elegant stairways for homes, castles, ruins, or modern environments with curve-guided precision.

Highly Versatile and Beginner Friendly
Zero modeling needed — just draw a curve, adjust some sliders, and your stairway is ready to go.

Designed with Realism in Mind
Stair height, handrail spacing, and base control mimic real-world dimensions and build logic.
