# Add content

The right **Content Panel** in Space Studio places models, primitives, lights, and annotations in map coordinates. The map describes the physical space; Content describes the digital experience anchored to it.

## Open the panel

Open a Ready map in Space Studio and select **Content** in the top bar. The canvas makes room for the panel. Select its title to collapse the body, or drag its left edge to resize it.

## Add objects

Under **Scene**, select **+ Add**:

- **Geometry** adds Box, Sphere, Cylinder, or Plane primitives.
- **Light** adds Ambient, Directional, or Point lighting.
- **Model** imports `.glb` or `.gltf` and its dependent assets.
- **Annotation · Tag** places a label on a real surface and requires a pickable scene mesh.

Prefer GLB for production so geometry, materials, and textures travel as one file. Optimize texture resolution, material count, and triangles for target mobile devices.

## Place and edit

Select an object in Scene, then use **Translate**, **Rotate**, or **Scale**. **Undo / Redo** navigates that object's edit history and **Reset** restores its pre-edit transform. Use the gizmo for coarse placement and numeric properties for final alignment. Keep Content in the shared map Origin; do not move the whole map to fix one object.

## Scene management

Visibility controls hide objects without deleting them. Delete removes the selected object; global visibility and delete-all actions affect the full Scene. Parent-child organization keeps related parts together, and child transforms are relative to the parent.

## Save and verify

Select the **Save** icon beside Scene to persist Content. Unsaved browser changes may be lost after refresh or close. Reopen the map and verify placement, scale, orientation, lighting, and performance on Android WebXR, iOS App Clip, and WeChat targets. Use **Launch** in the top bar for an AR preview.
