Stair Builder

WHAT IS STAIR BUILDER PLUGIN?
Stair Builder is a powerful parametric Cinema 4D generator designed to fully automate the creation of complex stair systems. Instead of wasting hours modeling individual steps, railings, and structural supports, this intuitive plugin allows you to build flawless, highly accurate stairs procedurally. From classic straight concrete stairs to intricate spiral setups, every single element, including treads, stringers, railings, and even integrated LED lighting, can be customized in real-time through the Attribute Manager and saved into a dedicated preset system.

PLUGIN FEATURES
- Comprehensive Stair Typologies: Easily generate standard Straight, Two-Flight, L-Stairs, U-Stairs, Concrete, Open-Treads, and both Round or Square Spiral stairs.
- Fully Parametric Workflow: Rebuild and adjust your entire stair geometry instantly by simply changing values like step count, riser height, and depth.
- Advanced Landing Controls: Seamlessly create flat or stepped transitions, 2-to-3 piece wedge landings, and custom near/far side extensions.
- Versatile Structural Supports: Choose from multiple stringer types including Side Straight, Center Profiled, and a specialized Side Stepped option for a folded-plate modern look.
- Complete Modular Railing System: Procedurally build and configure every part of a railing layout, from main handrails and posts to mid rails, foot rails, balusters, solid panels, or wires.
- Custom Mesh & Profile Support: Inject your own custom 3D models for posts and balusters, or link closed 2D splines to drive unique handrail profiles.
- Integrated Step LED Lighting: Toggle a built-in light strip geometry under each tread with precise control over width, distance, and depth, perfect for modern emissive materials.
- Optimized Viewport Performance: Utilizes render instances for custom elements and heavy railing runs, keeping your Cinema 4D scene fluid and fast.
- Advanced Material & UV Mapping: Includes dedicated slots for structural and railing elements with automated UVW coordinate generation and texture rotation for precise grain alignment.
- Robust Preset System: Save and load self-contained templates for entire stairs, railings, or specific custom assets, complete with bundled geometries and materials.
- and much more!

PLUGIN ACTIVATION LICENSE
Important: with the purchase of the plug-in you are eligible for 3 activations license. This means that you can activate this plugin on:
- 3 cinema 4d releases on 3 different workstations, (be careful so you immediately run out of licences)
- 3 different versions of Cinema 4D on the same workstation, so that you consume 1 activation each time you update the software (e.g. R22-23-24).
Once the 3 activations are used up, the plugin must be re-purchased as new, considering the low cost of the plugin it is a kind of subscription but you can manage it as you like. This plugin will be activated based on your Cinema4D serials or subscription license. There are important activation differences from other C4Dzone plugins so it doesn't automatically activated after download. Our office is located in Italy (GTM+1). We need at least 48 hours for the activation process.
