Spatial Editor (

Spatial SDK projects to create immersive Meta Horizon OS experiences.
- Layout both 2D and 3D objects without writing any code, which speeds up iteration and creation.
- Assign Spatial SDK components to objects directly within Spatial Editor instead of managing this logic in code.
- Use tooling that’s familiar to 3D artists and designers, facilitating faster and more efficient collaboration.
- Let AI agents create and manipulate 3D scenes programmatically using the built-in mse-agent command-line tool.
