Create high-poly and low-poly architectural buildings in Unity using spline workflows. Fast, customizable, and optimized for game environments and architectural visualizationCompatible with Built-in, URP, and HDRP. Tested on Unity 2021 LTS and newer. Demo scenes use Built-in pipeline by default; URP/HDRP can be upgraded via Unity’s tools. Fully supports desktop and mobile and all platforms.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.Key Features:Spline-Based Building Generation – Quickly draw splines to define building shapes, walls, doors, and windows directly in the Unity Editor.High-Poly & Low-Poly Modes – Seamlessly switch between detailed high-poly models and optimized low-poly versions for performance-critical projects.Fully Customizable Assets – Replace meshes, adjust materials, change floor counts, roof heights, window and door distributions, and edge profiles.Procedural Workflow – Automate repetitive tasks and generate modular buildings with minimal manual modeling.Performance Optimized – Built-in poly density controls to ensure smooth gameplay on both desktop and mobile platforms.Cross-Pipeline Support – Works with Unity Built-in Render Pipeline, URP, and HDRP.Material & Submesh Preservation – Combine meshes while keeping original submeshes and material assignments intact.Demo Scenes Included – Ready-to-use sample scenes to showcase workflows and help you get started instantly.Modular & Extendable System – Designed to easily integrate with other procedural tools, level design frameworks, or custom game logic.Ideal for Multiple Genres – Perfect for architectural visualization, city builders, open-world games, strategy titles, and stylized mobile games.Lightweight & Editor-Friendly – Execute in edit mode to speed up prototyping and reduce iteration time.Roof Generation Tools – Customizable roof styles, edge controls, and adjustable roof height to fit any building type.Flexible Mesh Alignment – Ensures accurate vertex matching and seamless surface-based alignment between modular parts.Optimized for Mobile – Low-poly mode and material batching options ensure stable framerate across iOS and Android devices.Support for Future Expansion – System architecture allows for additional prefabs, procedural modifiers, or future spline extensions.
