Spline Architect v1.3.6 is a powerful and versatile spline tool that introduces innovative ways to work with splines in both 3D and 2D environments. It includes a core package and a range of optional addons, making it ideal for creating roads, intersections, curved structures, train tracks, camera paths, and character movement systems.
The tool features Terrain Tools for generating mountains, rivers, paths, and entire worlds using splines, and Object Cloning to replicate GameObjects or sequences along splines. Deformation capabilities allow users to deform meshes, mesh colliders, prefabs with hierarchies, LOD groups, and decals (projection decals are not supported), with options to apply deformation effects, add layered noise, snap deformations to control points or GameObjects, and export deformations as mesh assets.
Spline connectors enable looping, splitting, joining, and linking of splines, with control point snapping to grids for precise 90° or 180° turns. Splines can be connected to create seamless transitions and moved using spline connectors.
Animation support allows for animating deformations or GameObjects along splines via Unity’s Animation System or custom scripts, including spline-based animations and control point effects for warping. Performance is optimized through multithreading, Unity Burst, cached positions and normals, and real-time monitoring of spline length and memory usage. The tool supports building games without mesh export, with optional stripping of unwanted components, and is optimized for low-end mobile devices.
A fully exposed API enables runtime or editor creation of splines, segments, deformations, and followers. It includes a built-in pooling system for dynamic deformation updates, supports instantiation from prefabs, and provides no DLL dependencies—allowing full code access and editing. Numerous example scripts are included to help developers get started.
