Spline Architect v2.2.1 (27 Mar 2026) is a powerful spline tool that introduces innovative workflows for working with splines in both 3D and 2D environments. It consists of a core package and a range of optional addons. The tool is ideal for creating roads, intersections, curved structures, train tracks, camera paths, and character movement systems. Users can also develop custom traffic or train systems using its fully exposed API, with example scripts provided.
Key features include:
- Terrain Tools: Create mountains, rivers, paths, and entire worlds using splines.
- Object Cloning: Clone GameObjects or sequences of objects along splines.
- Deformation: Deform meshes, mesh colliders, prefabs with hierarchies, LOD groups, and decals (projection decals not supported). Apply deformation effects to control points, add layered noise, snap deformations to control points or GameObjects, and export deformations as mesh assets.
- Splines & Spline Connectors: Loop, split, join splines; snap control points to grids for perfect turns; connect control points to spline connectors; link splines for seamless transitions; use connectors to move splines dynamically.
- Animation: Animate deformations or GameObjects along splines via Unity’s Animation System or custom scripts; animate splines using connectors or script; move objects between linked splines; add warp effects via control point animations.
- Performance: Multithreaded with Unity Burst for optimal performance; uses cached positions and normals; provides real-time view of spline memory usage, length, and other metrics; supports building games without mesh export; allows stripping unwanted components from final builds; optimized for low-end mobile devices.
- API: Fully exposed API for creating splines, segments, deformations, followers, and more at runtime or in the editor; supports dynamic updates via built-in pooling; enables instantiation of splines and deformations using prefabs; no DLL files—code is fully exposed and editable; includes multiple example scripts to assist with implementation.
