The Scene

• (1) Basic Addressables paths. The screenshot shows the paths in Unity Editor on MacOS system.

• (4) and (5) loads images and display them. (4) only shows images from LocalStatic group, while (5) shows images dynamically loaded from several Remote* groups.
• (6) checks if the catalog needs update. If so, (7) will show up which downloads the catalog and the associated bundles.
• (8) clears all the cached bundles, but preserve the latest catalog. It frees up user spaces. A user needs to redownload the bundle after clearance.
