Curvy Splines is a spline toolkit for Unity, officially positioned as βThe Ultimate Spline Solution.β It is mainly aimed at path systems, procedural modeling, and level-editing needs in games and real-time 3D projects, and can be used both inside the Unity Editor and at runtime. The page highlights that it has maintained a 5-star rating since 2013 and is available on the Unity Asset Store.
In terms of functionality, Curvy Splines offers fairly broad coverage. First, it supports spline movement, allowing objects such as cameras, trains, and flying creatures to move along dynamic paths, with controllers that support physics, events, and junctions. Second, it provides procedural mesh generation, making it relatively inexpensive to create roads, railways, cables, and similar structures. Third, it supports mesh deformation, allowing meshes such as fences and wire mesh to conform to level design. Fourth, it includes object placement, for arranging elements such as poles, rocks, and asteroids throughout a scene. For tool developers, it also provides a documented API that can be used to build track editors, wall builders, or pipe builders.
The tool is explicitly built for Unity, and it specifically notes compatibility with Unityβs Splines package. Projects can be migrated using the free Converter For Unity Splines, or both solutions can be used side by side. The website provides links to a Features Summary, User Manual, Tutorials, API Reference, Release Notes, and Forum, so the documentation ecosystem appears fairly complete. As for pricing, the page only states that it is available on the Unity Asset Store; it does not disclose a specific price, licensing model, or whether it uses a subscription.
Its strengths are that its feature set is tightly focused on Unity spline workflows, covering movement, generation, deformation, placement, and secondary development. It also supports both editor and runtime scenarios, making it suitable for indie developers, technical artists, level-tool developers, and larger studios. The downside is limited transparency: it does not state whether it is open source, whether source code is included, its exact price, payment methods, or accessibility from mainland China. In addition, it is clearly tied to the Unity ecosystem and is not suitable for Unreal, Godot, or general-purpose CAD/modeling workflows.
The page does not provide information about mainland China access, network connectivity, payment methods, or localization, so china_access can only be rated as unknown. In practice, purchasing may depend on the accessibility of the Unity Asset Store and the availability of payment options. Alternatives include Unityβs official Splines package, as well as other path, road-generation, spline, and procedural mesh plugins on the Unity Asset Store.
