The Package Manager window provides several ways to help you find a specific package:
|(A)||Packages list context||Choose the “context” that determines which packages appear in the list. The context might be the source of the package, such as a registry server, the Asset Store, or the Unity Editor itself (for built-in packages); however, the In Project context displays only those packages that are already installed in the current project, regardless of their origin.
For example, you can choose the My Assets context to show only Asset Store packages available to you in the list, or choose the In Project context to show only Unity packages that are already installed in your project.
|(B)||Sort||Sort the list of packages in either ascending or descending order by name, published date (Unity packages only), purchased date (Asset Store packages only), or update date.
For example, if you look for a Unity package that has a very recent update but can’t remember the name of it, try sorting by update date in descending order and browse the list from the top down to find it.
|(C)||Asset Store Filters||Choose how to narrow down the list of Asset Store packages using these groups:
- Status (hidden, deprecated, no labels)
- Categories (2D, 3D, audio, templates, tools, etc.)
- Labels (custom labels you define in the Asset Store)
|(D)||Search||Use the search box to look for a Unity package or an Asset Store package by name.|
These controls help narrow down which packages appear in the list view and in what order. This makes it easier to find what you are looking for or help you browse when you don’t know exactly what you want.
When you use several of these controls at the same time, you narrow the set of matches that appears in the list.
After you find the package you need, then you can locate a specific version from the list.
In Unity, open the Package Manager window (navigate to Unity’s main menu and go to Window > Package Manager).
