Spline V2 launches with rebuilt 3D editor, AI agents, WebGPU, and new desktop app

The browser-based 3D design platform Spline has gone through one of its biggest overhauls with the launch of Spline V2, introducing a redesigned editor, WebGPU rendering, new modeling and material tools, and deeper support for AI agents. A new built-in AI Agent can inspect and modify scenes, work with objects, materials, lighting, events and states, arrange elements using procedural tools and a constraint solver, and generate HTML or JavaScript connected directly to the scene.
