title: "`AmbientLight` split into a component and a resource"
pull_requests: [21585]

The AmbientLight used to be both a component and a resource. In 0.18, we've split this in two separate structs: AmbientLight and GlobalAmbientLight. The resource GlobalAmbientLight is the default ambient light for the entire world and automatically added by LightPlugin. Meanwhile, AmbientLight is a component that can be added to a Camera in order to override the default GlobalAmbientLight. When appropriate, rename AmbientLight to GlobalAmbientLight.

Before:

app.insert_resource(AmbientLight {
    color: Color::WHITE,
    brightness: 2000.,
    ..default()
});

After:

app.insert_resource(GlobalAmbientLight {
    color: Color::WHITE,
    brightness: 2000.,
    ..default()
});
