Reduce file size with Clean Up Scene

The Clean Up Scene tool in the File menu lets you remove empty or unused assets from your scene. This lets you clean up extraneous objects, helping you organize your scene and reduce file size.

To remove assets from a scene:

Important: Clean Up Scene is not undoable; back up your scene before triggering a cleanup.

1. Select File Clean Up Scene.
2. In the Clean Up Scene window, select which asset types you want to remove.
3. Click Clean Now.

Tip: Store the currently-selected cleanup operations as the default operation by using the Set as Default button.
