When you “remove” a UPM packageA Package managed by the Unity Package Manager. Refer to Packages.
See in Glossary from your project, the Package Manager is actually removing the project’s direct dependencyA direct dependency occurs when your project “requests” a specific package version. To create a direct dependency, you add that package and version to the dependencies property in your project manifest (expressed in the form package_name@package_version
). More info
See in Glossary from your project manifestEach Unity project has a project manifest, which acts as an entry point for the Package Manager. This file must be available in the <project>/Packages
directory. The Package Manager uses it to configure many things, including a list of dependencies for that project, as well as any package repository to query for packages. More info
See in Glossary. The result of removing the direct dependency varies, based on the dependencies for the package you are removing:
alembic@1.0.7
package which in turn depends on the timeline@1.0.0
package, then your project has an direct dependency on Alembic and an indirect dependency on Timeline. More infoMake sure you understand these important notes before you begin:

Open the Package Manager window and select In Project from the PackagesPackages are collections of assets to be shared and re-used in Unity. The Unity Package Manager (UPM) can display, add, and remove packages from your project. These packages are native to the Unity Package Manager and provide a fundamental method of delivering Unity functionality. However, the Unity Package Manager can also display Asset Store packages that you downloaded from the Asset Store. More info
See in Glossary drop-down menu.
Select the package you want to remove from the list of packages. The details view now displays that package’s information.
Click the Remove button. If this button is:
When the progress bar finishes, the package disappears from the list.
If you want to restore a removed UPM package, follow the instructions to install a UPM package from a registry or install a UPM package from the Asset Store.
Note: You can remove multiple packages with one click by using the multiple select feature. For more information, refer to Perform an action on multiple packages or feature sets.
You can only remove packages which are not required by another package or a feature set. The Package Manager enforces this by disabling the Remove button for all required packages.
Required by: | Description: |
---|---|
A feature set | If a feature set requires the package, it displays a lock icon () in both the list view and in the details view. The details view also displays the name of the feature set that requires the package below the package name in the details view. However, even if you click the Unlock button, you still can’t remove the package from your project until you remove all feature sets which require it. Unlocking the package lets you request a different version for your project, but it still doesn’t let you remove it. |
Another package | If one or more packages require the selected package, the Remove button is disabled. You can find the name of the package that has the dependency from the Dependencies tab in the details view. If you don’t need the other packages, you can remove them and the Package Manager automatically removes this package too. |
Note: You can unlock multiple packages with one click by using the multiple select feature. For more information, refer to Perform an action on multiple packages or feature sets.
