Access the Asset Store

You can access the Asset Store website at https://assetstore.unity.com/.

In Unity 6.0 and later, you can open the Asset Store website in the Unity Editor from the Asset Store dropdown in the toolbar. You can also use this dropdown to open your downloaded assets in the Package Manager Window.

In all supported versions of Unity, you can search for your purchased and downloaded Asset Store packages in the Package Manager window.

Asset Store package types

Asset Store packages are collections of files and data from Unity projects, or elements of projects. An Asset Store package type is either a UPM package or an asset package (.unitypackage format). When you add an Asset Store package to your project, the Unity Package Manager unpacks the package and maintains its directory structure and metadata about assets. This metadata includes information such as import settings and links to other assets.

Both package types have their advantages, as follows:

Asset packages: Best for one-off imports or sharing assets without setting up a package registry and requires fast one-off iterations. It is suited for content assets such as 3D models and__ UI__（即用户界面，User Interface）让用户能够与您的应用程序进行交互。Unity 目前支持三种 UI 系统。更多信息

Unity Package Manager (UPM) packages (currently in beta testing): Can be versioned, and excluded from source control. Use UPM when you need version control, dependency management, or plan to maintain the package across multiple projects. For more information about UPM packages, refer to Introduction to packages.
