-
Clear any items you don’t want to import and click Import.
The Package Manager puts the contents of the imported Asset Store package into the
Assetsfolder, so that you can access them from your project window.
Note: You can download multiple packages with one click by using the multiple select feature. For more information, see Perform an action on multiple packages or feature sets.
Importing a complete project from the Asset Store
A complete project contains assets and project settings. The process for importing a complete project is similar to other Asset Store packages, except for an additional step for project settings.
The project settings in the complete project might conflict with settings in your project, so when you import a complete project from Asset Store, the Package Manager offers a choice.
Choose Import if you’re sure that you want to add the package’s assets to your project. An Import Unity Package dialog box appears, like the one pictured below. Clear any asset content you don’t want to import and click Next. The second step of the dialog box lists the package’s project settings. If you have any of those project settings in your project, Package Manager identifies them with an Override flag; they will be overwritten with the project settings from the package unless you clear the selection. Clear any project settings you don’t want to import and click Import.
Choose Switch Project if you want to explore the package’s assets and project settings in a safe environment. Choosing Switch Project creates a new, temporary project that contains only that package’s assets and project settings. After exploring the temporary project, you can close it without saving. If you want to continue to use that package in your main project, return to your main project and import the package again. Choose Import on the warning dialog box that appears.
