Spline Architect v1.5.1 is a powerful spline tool that introduces innovative workflows for working with splines in both 3D and 2D environments. It includes a core package and a range of optional addons available separately. The tool is ideal for creating roads, intersections, curved structures, train tracks, camera paths, and character movement systems.
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, and join splines; snap control points to a grid for perfect turns; connect control points to spline connectors; link splines for seamless transitions; and move splines using spline connectors.
- Animation: Animate deformations or GameObjects along splines using Unity's Animation System or custom scripts; animate splines via spline connectors or scripts; move objects between linked splines; and apply warp effects via control points.
- Performance: Multithreaded with Unity Burst for optimal performance; caches 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 the final build; and is optimized for low-end mobile devices.
- API: Fully exposed API enables runtime or editor creation of splines, segments, deformations, and followers; dynamic updates via built-in pooling; custom traffic or train systems (with example scripts); instantiation of splines and deformations using prefabs; no DLL files—code is fully exposed and editable; includes numerous example scripts to assist beginners.
