Spline

Higgsfield demoed GPT-6 Astra creating interactive 3D experiences including a wardrobe, room planner, Tokyo rail tracker, and hand-tracked story theatre. A Spline robot demo adds collision detection and pose correction to its walking solver.

Spline says Hana V2 lets agents generate through MCP or its in-app tools. The release adds PBR GLB and GLTF import, SVG and PDF export, a WebGPU canvas, and improved vector editing.

Spline rebuilt its web-based 3D editor with Agent Mode and an MCP connection for its desktop app. V2 also adds a WebGPU engine, PBR and HDR workflows, and scripting for code-enabled scenes.
