The Managed Stripping Level property determines which rules the Unity linker follows when it analyzes and strips your application's code. Increasing the managed stripping level expands the scope of the linker's search for unused code but also increases build time.
To change the Managed Stripping Level property:
- Go to Edit > > Player.Project Settings
?
- In Other Settings, navigate to the Optimization heading.
- Set the Managed Stripping Level property to the desired value.
Property | Function |
|---|---|
| Disabled | Unity doesn't remove any code. This setting is only available for the Mono scripting backend and is the default setting in that case. |
| Minimal | Unity searches only the This setting is useful for projects where usability is of higher priority than build size. This is the default setting if you use the IL2CPP scripting backend. |
| Low | Unity searches for unused code in all Note: The Low managed stripping level is marked for future deprecation and using it is not recommended. Use Minimal or Medium instead. |
| Medium | Unity partially searches all assemblies to find unused code. This setting applies a set of rules that strips more types of code patterns to reduce the build size. Although Unity doesn't strip all possible unused code, this setting does increase the risk of undesirable or unexpected behavior changes. |
| High | Unity performs an extensive search of all assemblies to find unused code. At this setting, Unity prioritizes size reduction more than code stability and removes as much code as possible. This search can take much longer than for lower stripping levels. Use this setting only for projects where a compact build size is extremely important.
