Toolbar
The toolbar is the global header at the top of the editor window. It groups project-level actions on the left, viewport controls in the center, and history / publishing actions on the right.
Left group
| Control | Action |
|---|---|
 | Clicking this returns to the project dashboard. |
Center group
| Control | Action |
|---|---|
 | Adds a new entity to the scene (cube, sphere, plane, light, camera, etc.). |
 | Launches a preview of your experience in a separate browser window using the current saved snapshot. |
Right group
| Control | Action |
|---|---|
 | Reverts the last scene-affecting action. Bound to Cmd/Ctrl + Z. |
 | Re-applies the last undone action. Bound to Cmd/Ctrl + Shift + Z. |
 | Writes the current scene to disk. Bound to Cmd/Ctrl + S. |
 | Uploads the project to Relu Spatial cloud and makes it shareable. |
 | Opens the global project settings menu. |
TIP
Save and Publish are independent. You always need to save before previewing or publishing, preview/publish read the on-disk snapshot, not the in-memory state.
