Claude drives Blender via MCP: imports Echo-3 3DGS scenes, adds physics, relights
risingodegua · x · 2026-11-13
A developer showcased a workflow built on Blender 5.3's native 3D Gaussian Splatting support: Claude, driving Blender through the Blender MCP add-on, imported a SpAItial Echo-3 generated world and manipulated it. The pipeline:
- Export the world from the SpAItial app as SPZ; Blender 5.3 imports it natively as a Gaussian splat point cloud — 10M splats in about a second.
- Rotate 180° on X to match Blender's axes; Echo-3 worlds use real-world metres, so floor and eye height align with Blender units.
- Export the collision mesh (sits within 6 mm of the splats) to serve as floor and walls for rigid body physics.
- Relighting: splat colors are rebuilt from radiance data and fed into a shader that reacts to Blender lights, with the hidden collision mesh casting shadows.
Claude ended up relighting the cafe scene from day to night and dropping physics objects into it.
