# Overriding Defaults

In some cases, you may find that default values set by the Live Config schema are not suitable for your project's use-case. To work around this, **projects can define a set of live config override files** as needed.

Overrides to schema default values can be specified by defining a set of `{config-name}.override.json` files under certain paths in your project (see [override levels](#override-levels) below).\
Override files should be **formatted as a subset of the live config settings defined in your schema**. For instance:

{% code title="game.override.json" %}

```json
{
    "Activities":
    {
        "MaxActivitiesPerPlayer": 99
    }
}
```

{% endcode %}

is a valid override file for the `game` Live Config. As such, any world that is started for this project would launch with `"Activities.MaxActivitiesPerPlayer"` setting set to 99.

(**Note**: any settings that are defined in an override file but not in the present in the schema will be ignored)

### Override levels

Currently, we support the following levels of override, which will be applied in the listed order:

* **The Project level**\
  These overrides will apply for all worlds running on the project content build.
  * Directory: `{project-root}/Config/LiveConfig/Overrides/`
    * e.g.: `.../Overrides/game.override.json`\\
* **The Map level**\
  These overrides will apply for all worlds running on the given map. The override directory name **must exactly match** the short package name of the map asset in Unreal.
  * These overrides **takes precedence over any overrides on the project-level.**
  * Directory: `{project-root}/Config/LiveConfig/Overrides/{map-name}/`
    * e.g: `.../Overrides/Meadow/game.override.json`\\
* **The Editor**\
  Certain live config settings may only be applicable on a cloud deployment. In these instances, you can specify editor overrides on your project build. Note that PIE sessions will also apply the project/map level above as appropriate.
  * Project Editor override
    * This override will apply on PIE only for this project, and **takes precedence over Project- and Map- level overrides.**
    * Directory: `{project-root}/Config/LiveConfig/Overrides/Editor/`
      * e.g: `.../Overrides/Editor/game.override.json`
