Learn to add a prefab to the scene as an instance.
What Is a Prefab Instance?
When you drag a Prefab asset from the Project window into a scene, Unity creates an instance connected to that asset. An instance is a Prefab example that can be edited in the scene. You can create multiple instances from the same Prefab asset.
// Prefab Asset
// Scene Instance A
// Scene Instance BEditing an Instance
You can change properties such as position, rotation, or scale on a Prefab instance in the scene. These changes can be stored as overrides on the instance. The Overrides menu in the Inspector helps you manage differences between the source and the instance.
// Position Override
// Rotation Override
// Scale OverridePractice Work with a Prefab Instance
Use an assigned Prefab instance reference from the Inspector to change the object's name. If the reference is not empty, set its new name to ActiveCrate and print the result to the console.
