Spline Buildings Generator

SplineArchitecturalBuilder is a powerful Unity package designed to help developers, artists, and level designers quickly generate both high-poly and low-poly architectural buildings using intuitive spline workflows. By simply drawing splines, you can instantly define building layouts, extrude walls, place doors and windows, and create fully customizable architectural assets without leaving the Unity Editor.

The package is built for flexibility and customization – you can easily swap meshes and materials, adjust floor counts, roof styles, and edge details, and control poly density depending on the needs of your project. This makes it suitable for a wide range of genres, from realistic architectural visualization and city builders to stylized low-poly mobile games.

Optimized for performance, SplineArchitecturalBuilder allows seamless switching between high-detail and mobile-friendly low-poly versions, ensuring smooth gameplay across platforms. The system is compatible with Unity’s Built-in Render Pipeline, URP, and HDRP, making it versatile for any project setup.

Whether you are creating large urban environments, modular building kits, or procedural cities, this tool accelerates your workflow, reduces modeling time, and gives you full creative control over the look and performance of your architectural assets.
