Disable a built-in package

You can disable a Built-in packageBuilt-in packages allow users to toggle Unity features on or off through the Package Manager. Enabling or disabling a package reduces the run-time build size. For example, most projects don’t use the legacy Particle System. By removing the abstracted package of this feature, the related code and resources are not part of the final built product. Typically, these packages contain only the package manifest and are bundled with Unity (rather than available on the package registry).

if you don’t need some modules and you want to save resources. However, when you disable a built-in package, the corresponding Unity functionality is no longer available.

Disabling a built-in package results in the following:

  • If you use a Scripting API implemented by a disabled package, you get compiler errors.
  • Components implemented by the disabled built-in package are also disabled, which means you can’t add them to any GameObjects. If you have a GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more.

    window but they’re grayed out to indicate that they’re not available.
  • When building a game, Unity strips all disabled components. For build targets which support engine code stripping (like Web, iOS, and Android), Unity doesn’t add any code from a disabled built-in package.
