# Customizing Maps: Layered Maps
|
|
|
|
Utilizing levels in your custom map enables multiple people to work on a single map concurrently. It also allows you to use the Python API to load and unload layers on your map during a simulation, just like the [layered CARLA maps](core_map.md#layered-maps).
|
|
|
|
This guide will explain how to add a new level, how to add assets to a level, and how to configure a level to be always loaded or not.

## Add a new level
|
|
|
|
All new levels in your map will be nested within the parent level, known as the _Persistent Level_. To create a new level:
|
|
|
|
__1. Open the levels panel.__
|
|
|
|
1. In the Unreal Engine editor, open _Window_ from the menu bar.
|
|
2. Click on _Levels_.
|
|
|
|
__2. Create a new level.__
|
|
|
|
1. In the _Levels_ panel, click on _Levels_ and select _Create New..._.
|
|
2. Choose _Empty Level_.
|
|
3. Save the level in `Content/Carla/Maps/Sublevels/<map_name>/`. To integrate the level with the CARLA Python API, use the naming convention `<map_name>_<layer_name>`, e.g., `TutorialMap_Buildings`. For a list of available layers, check [here](core_map.md#carla-maps).

## Add assets to a level
|
|
|
|
__1. Select the level to which you want to add assets__.
|
|
|
|
In the _Levels_ panel, double-click the level to which you would like to add assets. Make sure the level is unlocked by toggling the lock icon.
|
|
|
|
__2. Select the assets to add.__
|
|
|
|
1. Select all the assets you would like to add to the level.
|
|
2. Right-click and go to _Level_.
|
|
3. Click on _Move Selection to Current Level_.
|
|
|
|
__3. Save the level.__
|
|
|
|
If a level has pending changes to save, you will see a pencil icon next to it in the _Levels_ panel. Click this to save the changes.

## Configure level loading options
|
|
|
|
Levels can be configured to be able to be toggled or to be always loaded. To configure the level for either option:
|
|
|
|
1. Right-click the level in the _Levels_ panel and go to _Change Streaming Method_.
|
|
2. Choose the desired setting:
|
|
1. _Always Loaded_: The level __will not be able__ to be toggled via the Python API.
|
|
2. _Blueprint_: The level __will be able__ to be toggled via the Python API. A blue dot will appear beside the level name.
|
|
|
|
Regardless of the setting, you will still be able to toggle the level in the editor by pressing the eye icon.

## Next steps
|
|
|
|
Continue customizing your map using the tools and guides below:
|
|
|
|
- [Add and configure traffic lights and signs.](tuto_M_custom_add_tl.md)
|
|
- [Add buildings with the procedural building tool.](tuto_M_custom_buildings.md)
|
|
- [Customize the road with the road painter tool.](tuto_M_custom_road_painter.md)
|
|
- [Customize the weather](tuto_M_custom_weather_landscape.md#weather-customization)
|
|
- [Customize the landscape with serial meshes.](tuto_M_custom_weather_landscape.md#add-serial-meshes)
|
|
|
|
Once you have finished with the customization, you can [generate the pedestrian navigation information](tuto_M_generate_pedestrian_navigation.md).
