Local workspace

When using Mega Studio for Unity development, to ensure data security and editing efficiency, the tool employs a local workspace mechanism. When you load cloud Block data, it is actually downloaded to this local space. Operations like placing virtual objects and modifying annotations first occur locally until you manually perform a synchronization operation.

Unity scene saving and loading

  • Saving: In Unity's menu bar, click File → Save As... to save, or use the shortcut Ctrl + Shift + S directly.
    save

  • Loading: In Unity's menu bar, click File → Open Scene to load a scene, or double-click to open a saved scene. You can also use the shortcut Ctrl + O.
    load

Saving tool node prefabs

Select the EasyAR.Mega.* tool node and drag it into the Assets folder in the Project window. Then close the scene without saving.
load

Next time, create a new scene and drag the saved Prefab from the Assets folder into the scene.
load

If Block data was already loaded in the scene when creating the Prefab, you will be prompted to load it when adding it to a new scene.

Core mechanism

The core mechanism of the local workspace prevents data loss through "manual synchronization." During regular use, until you explicitly press upload, download, or service selection buttons in the tool, any local modifications won’t affect service data, nor will service data changes immediately update in the tool.

Data synchronization rules:

  • Local \(\rightarrow\) Cloud: Any modifications made in Unity won’t automatically save to the cloud server. You must explicitly click the "Upload" button on the toolbar for changes to take effect.
  • Cloud \(\rightarrow\) Local: If cloud data changes (e.g., others update the map), these changes won’t automatically appear in your editor. You must explicitly click "Download" or "Refresh" to fetch the latest data.
Note

If login times out, the tool will automatically re-login. At this point, data like the Block list may refresh, but Block data, annotation data, and other explicitly downloaded data won’t refresh automatically.
