spline architect

Spline Architect is a Unity spline package by Mike Danielsson that gained attention for its GPU instancing support in version 2.7.2. The tool can update and render up to one million lightweight spline-instance records along splines using Unity's instanced drawing API, rather than moving one million full GameObjects. This distinction matters for developers evaluating the tool's performance claims. The package is relevant to Unity developers working on large-scale scenes, such as those involving roads, rails, or other path-based objects, where efficient rendering of many instances is critical. The tag covers discussions about the tool's capabilities, implementation details, and practical implications for scene scale and performance in Unity projects.
