Compatible with Unity 2022 and 6000 across all render pipelines. Requires Unity's Collections package, minimum version is 2022.3.62f2.Example scenes are included for URP and HDRP, but not for the Built-in Render Pipeline.Spline Architect uses its own spline API, designed for ease of use and performance. Thanks to this custom API, Spline Architect runs 280% faster in mesh deformation, 115% faster in spline creation, and 45% faster when moving GameObjects along splines compared with the next-fastest tested spline tool. See the full performance tests here.Create roads, intersections, train tracks, pipes, curved structures, camera paths, character movement, and more. Use any 3D asset from the Asset Store, if it looks blocky, simply increase the resolution to make it smooth.🌐 Official Website📚 API Introduction🤖 Spline Architect Copilot💬 Discord➕ AddonsTerrain Tools - Create mountains, rivers, paths, entire worlds using splines.Object Cloning - Fill splines with meshes or GameObjects (Included).🧩 Splines & Spline connectorsBuild complex road networks and intersections using Spline Connectors.Move GameObjects along splines like you move GameObjects in the scene.Loop, split, and join splines.Snap control points to the grid and create perfect loops, 90° or 180° turns.Support for linking splines.Project control points onto surfaces.Create splines inside prefabs.🚧 DeformationDeform any type of mesh or mesh collider along splines.Fill and repeat GameObjects and meshes along splines.Deform LOD groups and decals (projection decals are not supported).Project meshes and GameObjects onto surfaces.Apply deformation effects to control points.Add noise effects to your deformed meshes.Scale meshes using Animation Curves.Deform meshes in 2D and 3D.🎮 AnimationAdd effects to control points to warp animations.Animate mesh deformations or GameObjects along splines.Animate splines using spline connectors or script.Move objects between linked splines.🧰 PerformancePowered by Unity Burst + Jobs, optimized for low-end mobile devices.GPU instancing is supported, easily move over 100,000 instances along splines.No need to export meshes, leave them on the spline for fast iterations.Strip unwanted components from final build when needed.💻 APINo DLL files, all code is exposed and editable.Create splines, deformations, followers, and more during runtime.Instantiate splines and deformations using prefabs.Dynamically populate splines.Code your own traffic or train system (examples included).A human has written around 99% of the codebase. The few lines written by AI (ChatGPT) have always been quality-checked and code-reviewed.ChatGPT helped with spelling, grammar, and wording in the API documentation.The texture 'asphalt01' was created using Polycam's AI-powered texture generation feature.
